[0034] It is understood that the features of the present invention discussed herein can be used with any type of percussive massage device. For example, the force meter and other features taught herein can be used with the percussive massage devices disclosed in U.S. Patent No. 10,357,425 (the '425 patent) and U.S. patent application Ser. No. 16 / 675,772, both of which are incorporated herein by reference in their entireties.

[0035] In one embodiment, a non-transitory computer-readable medium stores software instructions that, when executed by a processor, cause the processor to obtain a voltage of a motor of a percussive massage device, generate a lookup table relating the voltage to the force applied by the percussive massage device, and use the lookup table to display a magnitude of the force corresponding to the obtained voltage.

[0036] In one embodiment, the lookup table is generated by determining a maximum magnitude of force configured to be applied by the percussive massage device, determining a maximum magnitude of voltage configured to be applied to the percussive massage device from the power source, dividing the maximum magnitude of force into equal force increments, and dividing the maximum magnitude of voltage into equal voltage increments, where in one embodiment the number of equal force increments and the number of equal voltage increments are the same.

[0037] In another embodiment, a non-transitory computer-readable medium stores software instructions that, when executed by a processor, cause the processor to obtain a maximum power supply voltage of a percussive massage device; set the maximum power supply voltage to a maximum magnitude of voltage; divide the maximum magnitude of voltage into equal voltage increments, wherein the number of equal force increments and the number of equal voltage increments are the same; generate an updated lookup table relating voltages to forces applied by the percussive massage device corresponding to a range of voltages determined by the maximum power supply voltage; and display a calibrated force magnitude corresponding to the power supply voltage using the updated lookup table.

[0038] In another embodiment, a non-transitory computer-readable medium stores software instructions that, when executed by a processor, cause the processor to obtain at least two power supply voltages each corresponding to a force magnitude determined from the displayed force magnitude, measure the force applied by the percussive massage device using an external force meter for each of the at least two power supply voltages, and generate an updated lookup table relating voltages to the force applied by the percussive massage device corresponding to the measured force magnitude.

[0039] In one embodiment, a non-transitory computer-readable medium stores software instructions that, when executed by a processor, cause the processor to obtain a current magnitude of a battery pack of a percussive massage device, obtain a voltage magnitude of the battery pack, determine a power magnitude using the current magnitude and the battery pack voltage magnitude, generate a lookup table relating the power to the power magnitude applied by the percussive massage device, and use the lookup table to display a force magnitude corresponding to the obtained power magnitude.

[0040] In one embodiment, a non-transitory computer-readable medium stores software instructions that, when executed by a processor, cause the processor to: determine at least two force magnitudes determined from the displayed force magnitudes using current measurements and voltage measurements of the battery pack that each correspond to a force magnitude; measure the force applied by the percussive massage device using an external force meter for each of the at least two force magnitudes; and generate an updated lookup table relating power to the force applied by the percussive massage device corresponding to the measured force magnitudes.

[0041] In a preferred embodiment, in one embodiment, power from a power source is converted into motion. In some embodiments, the motor is an electric motor. The electric motor may be any type of electric motor known in the art, including, but not limited to, a brushed motor, a brushless motor, a direct current (DC) motor, an alternating current (AC) motor, a mechanically commutated motor, an electronically commutated motor, or an externally commutated motor.

[0042] In some embodiments, the actuated output or output shaft reciprocates at a speed of about 65 Hz. In some embodiments, the actuated output reciprocates at a speed greater than 50 Hz. In some embodiments, the reciprocating therapeutic device provides reciprocating motion at a speed ranging from 50 Hz to 80 Hz. In some embodiments, the actuated output has a maximum articulation rate between 50 Hz and 80 Hz. In other embodiments, the actuated output has an articulation rate between 30 Hz and 80 Hz. In certain embodiments, the actuated output has an articulation rate of about 37 Hz. In one embodiment, the actuated output has an articulation rate of about 60 Hz. In preferred embodiments, the actuated output articulates or reciprocates at a frequency between about 15 Hz and about 100 Hz. In even more preferred embodiments, the actuated output articulates or reciprocates at a frequency between about 25 Hz and about 48 Hz. In a most preferred embodiment, the actuated output articulates or reciprocates at a frequency between about 33 Hz and about 42 Hz. Any selected range within the specified ranges is within the scope of the present invention.

[0043] The actuation output may move through a predetermined range of reciprocating motion. For example, the actuation output may be configured to have an amplitude of 0.5 inches. In another embodiment, the actuation output may be configured to have an amplitude of a quarter inch. As will be appreciated by those skilled in the art, the actuation output may be configured to have any amplitude that is deemed therapeutically beneficial.

[0044] In some embodiments, the actuation output may be adjustable with a variable range of reciprocating motion. For example, a reciprocating treatment device may have an input for adjusting the amplitude of the reciprocating motion from a quarter inch up to one inch. In preferred embodiments, the actuation output moves with an amplitude between about 0.15 inches and about 1.0 inches. In even more preferred embodiments, the actuation output articulates or reciprocates with a frequency between about 0.23 inches and about 0.70 inches. In the most preferred embodiment, the actuation output articulates or reciprocates with a frequency between about 0.35 inches and about 0.65 inches. Any selected range within the specified ranges is within the scope of the present invention.

[0045] It is understood that the device operates most effectively within a range of combined frequencies and amplitudes. In developing this invention, the inventors determined that frequencies and amplitudes above the device's above-described ranges may cause pain, and that below the ranges the device will be ineffective and will not provide effective therapeutic relief or massage. Only when the device operates within the disclosed frequency and amplitude range combinations will the device provide efficient and beneficial treatment to the muscles targeted by the device.

[0046] In certain embodiments, the reciprocating therapeutic device has one or more components that adjust the speed of articulation of the actuation output in response to varying levels of power provided at the power input. For example, the reciprocating therapeutic device may have a voltage regulator (not shown) for supplying a substantially constant voltage to the motor over a range of input voltages. In another embodiment, the current supplied to the motor may be adjusted. In some embodiments, the operation of the reciprocating therapeutic device may be limited in response to the input voltage falling below a preset value.

[0047] In a preferred embodiment, the percussive massage device has a brushless motor, which has no gears and is understood to be quieter than a geared motor.

[0048] The device has a push rod or shaft that is directly connected to the motor by a pin. In a preferred embodiment, the push rod is L-shaped or has an arc shape. Preferably, the point where the push rod connects to the pin is offset from the reciprocating path traveled by the distal end 40 of the push rod (and massage attachment). This function is provided by the arc or L-shape. It should be understood that the push rod is designed so that the push rod 14 can transmit forces at least partially diagonally or arcuately along its shape rather than vertically, so that the motor can be placed at or near the center of the device, otherwise a protrusion would be needed to offset the motor and hold (and center) the shaft. The arc allows the push rod to have a close clearance with the motor, allowing the external housing to be smaller than similar prior art devices, thus further lowering the profile of the device. Preferably, two bearings are included at the proximal end of the push rod that connects to the motor to counteract diagonal forces and prevent the push rod from contacting the motor as it moves. Included at the proximal end of the push rod is a motor that is connected to counteract oblique forces and prevent the push rod from moving and contacting the motor.

[0049] In a preferred embodiment, the device has a touchscreen for stopping, starting, operating, etc. The touchscreen may have other functions. Preferably, the device has a thumbwheel or rolling button located near the touchscreen / on / off button to allow the user to scroll or navigate through the various functions. Preferably, the device also includes a variable amplitude or stroke. For example, the stroke can be or be made to vary between approximately 8-16 mm.

[0050] In a preferred embodiment, the device can be associated with and operated by an app or software running on a mobile device such as a phone, watch, or tablet (or any computer). The app can connect to the device via Bluetooth or other connectivity protocols. The app can have any or all of the following features: Additionally, any of the features described herein can be added directly to the device's touchscreen / scroll wheel or button(s). If the user walks or is too far from the device, the device will not function or operate. The device can be turned on and off using the app and the device's touchscreen or buttons. The app can control variable speed (e.g., anywhere between 1750 and 3000 RPM). A timer can be implemented to stop the device after a predetermined time. The app can also have various treatment protocols associated with it, allowing the user to select the protocol or body area they want to operate on. Once a protocol is selected to start, the device will execute the routine. For example, the device may operate at a first RPM for a first period of time, then at a second RPM for a second period of time, and / or at a first amplitude for a first period of time, then at a second amplitude. The routine may also have prompts (e.g., haptic feedback) to notify the user to move to a new body part. These routines or treatments may be related to recovery, increased blood flow, performance, etc., and each may have a pre-programmed routine or protocol. The routine may prompt or instruct the user to switch treatment structures (AmpBITS) or arm or rotating head positions. Prompts may include sounds, haptic feedback (e.g., vibrations on the device or mobile device), text instructions on an app or touchscreen, etc. For example, the app may instruct the user to start with the ball treatment structure with the arm in position 2. The user then presses start, and the device runs at the first frequency for a predetermined time.The app or device then prompts the user to begin the next step in the routine, instructing the user to change to the cone treatment configuration and place the arm in position 1. The user presses start again and the device runs at the second frequency for the predetermined time.

[0051] In a preferred embodiment, the app includes near-field communication (“NFC”) functionality or other features that allow a user's mobile device loaded with the app to scan an identifier, such as a barcode or QR code, that prompts the app to display predetermined information, such as the routines described above. During use, a user can tap or place their mobile device near an NFC tag (or scan a QR code) on gym equipment, and the app will display customized instructions, content, or lessons for using the equipment. For example, on a treadmill, when a user scans a QR code or NFC tag, the app recognizes that the user is about to use the treadmill. The app can provide instructions on how to use the equipment in conjunction with the treadmill and can begin a pre-programmed routine for using the treadmill. For example, the app can instruct the user to start with the left quad. Then, after a predetermined time (e.g., 15 seconds), the device will vibrate or provide other haptic feedback. The user then switches to the left quad, and after the predetermined time has elapsed, the device will vibrate again. The user can then begin using the treadmill. Any routine is within the scope of the present invention. In one embodiment, the device and / or app (i.e., the mobile device containing the app) can also communicate (e.g., via Bluetooth) with gym equipment (e.g., the treadmill).

[0052] The device may have a torque or force meter to inform the user of the amount of force being applied. A display associated with the force meter shows the amount of force being applied to the muscle. The force meter allows for more accurate and effective treatment. The device has a torque measurement sensor and display. The force that needs to be applied varies depending on the muscle the device is being used on and the benefit the user is trying to achieve (readiness, execution, recovery). Having a torque sensor allows the user to receive more accurate and personalized treatment. An app and touchscreen can provide force information to the user. The force meter can be integrated into a routine and the user can be given feedback on whether the pressure is too much or too little. The device may have a heat sensor or thermometer that can determine the temperature of the user's muscles and provide feedback to the device and / or app. Haptic feedback can also provide feedback for excessive pressure or force.

[0053] In a preferred embodiment, a percussive massage device has a motor mount for mounting a brushless motor to a housing and distributing force from the motor to the housing when the motor is operating. The motor is secured to a first side of the motor mount, and a second or opposite side of the motor mount is secured to the housing. The motor mount has multiple arms that space the motor from the housing and define a reciprocating space in which a push rod and associated components (such as a counterweight) reciprocate. Threaded fasteners connect the motor mount to the housing. In a preferred embodiment, damping members or legs are received on the shafts of threaded fasteners. Each damping member has an annular slot defined therein. The annular slots receive the housing, preventing direct contact of the threaded fasteners with the housing and reducing vibration-induced sound. The threaded fasteners are received in openings in tabs at the ends of the arms.

[0054] In a preferred embodiment, the motor is housed in a motor housing that is rotatable with the main housing. The motor housing is essentially equivalent to the gearbox housing of the related embodiment. In a preferred embodiment, the exterior of the motor housing has opposing openings that expose the motor on one side and the motor mount on the other side. The openings provide ventilation for the motor and allow the motor mount to be directly connected to the main housing.

[0055] In a preferred embodiment, the device has a touchscreen and buttons for operating the device. For example, the device may have a touchscreen, a center button for turning the device on and off, and a ring / rocker button that provides the ability to scroll left and right (e.g., for preset operations as described herein) and up and down (e.g., to control speed or frequency). The screen may also be a non-touchscreen.

[0056] In another preferred embodiment, any of the instruments taught herein can have the ability to vary the amplitude, thus providing longer or shorter strokes depending on the user's application or needs. Amplitude variation can also be part of the routines or presets discussed herein. For example, the instrument can have a mechanical switch that allows the eccentricity of the connector to be changed (e.g., between 4 mm and 8 mm). The mechanism can have a push button and a slider. The pin structure has a spring that returns it to the locked position.

[0057] In a preferred embodiment, the device has a touch screen for stopping, starting, operating, etc. The touch screen may have other functions as well. Preferably, the device has a thumb wheel or rolling button located near the touch screen / on / off button to allow the user to scroll or navigate through the different functions.

[0067] Although many embodiments are described herein, at least some of the described embodiments provide devices, systems and methods for reciprocating therapeutic devices.

[0068] 1-10 illustrate an embodiment of a percussive massage device 212 having a rechargeable battery (and replaceable or removable battery) 114. The device 212 is commercially referred to as the G3PRO. As shown in FIGS. 1-1A, in a preferred embodiment, the percussive massage device 212 has three handle portions (referred to herein as a first handle portion, a second handle portion, and a third handle portion) that cooperate to define a central or handle opening. All of the handle portions are long enough to allow a person to grasp a particular handle portion to utilize the device. The ability to grasp different handle portions allows a person to use the device from different angles on different body parts (when using the device on their own body), thus allowing them to reach body parts such as their back, which would not be possible without the three handle portions.

[0069] 1, first handle portion 143 defines a first handle portion axis A1, second handle portion 145 defines a second handle portion axis A2, and third handle portion 147 cooperatively define a third handle portion axis A3, cooperating to form a triangle. In a preferred embodiment, battery 114 is housed in second handle portion 145 and motor 106 is housed in third handle portion 147.

[0070] Figures 3-5 show a user's hands grasping the various handle portions. As shown in Figures 3-5, the lengths of each of the first, second, and third handle portions are sufficiently long so that individuals with large hands can comfortably grasp each handle portion with at least three or four fingers extending through the handle opening. In a preferred embodiment, first handle portion 143 has an inner edge 143a, second handle portion 145 has an inner edge 145a, and third handle portion 147 has an inner edge 147a, all of which cooperate to at least partially define handle opening 149. As shown in Figure 1, in a preferred embodiment, first handle portion 143 has a finger projection 151 having a finger surface 151a extending between inner edge 143a of the first handle portion and inner edge 147a of the third handle portion 147 and at least partially defining handle opening 149. As shown in Figure 3, during use, a user can place their index finger on finger surface 151a. The finger bumps and finger surfaces provide feedback points or support surfaces when the user places their index finger on the surface to help the user control and comfort use of the device. In a preferred embodiment, at least a portion of finger surface 151 a is straight (as opposed to the other "corners" of handle opening 149, which are rounded), as shown in FIG.

[0071] 1A shows preferred dimensions of the inner surface of the handle opening 149. It is understood that the inner surface comprises a series of flat curved surfaces. H1 is the dimension of the inner edge 143a of the first handle portion 143 (the length of the first handle portion). H2 is the dimension of the inner edge 145a of the second handle portion 145 (the length of the second handle portion). H3 is the dimension of the inner edge 147a of the third handle portion 147 (the length of the third handle portion). H4 is the dimension of the finger surface 151a (the length of the finger knob). R1 ​​is the dimension of the radius between the inner edges 143a and 145a, and R2 is the dimension of the radius between the inner edges 145a and 147a. In a preferred embodiment, H1 is approximately 94 mm, H2 is approximately 66 mm, H3 is approximately 96 mm, H4 is approximately 12 mm, R1 is approximately 6.5 mm, and R2 is approximately 6.5 mm, providing an arc length of approximately 10.2 mm. In this context, "approximately" means within 5 mm. In a preferred embodiment, the length of the inner edge of the handle opening is approximately 289 mm. The length of the inner edge of the handle opening can be between approximately 260 mm and approximately 320 mm for any combination of H1, H2, H3, H4, R1, and R2. It is understood that these dimensions are optimized so that a 95th percentile male can grasp any of the three handle portions with at least three, and preferably four, fingers extending through the handle opening to utilize the device. It is understood that any or all of surfaces R1 and R2 can be considered part of any of the three adjacent handle portions. As shown in FIGS. 1 and 1A, finger surface 151a is straight, and the inner surface of the first handle portion, the inner surface of the second handle portion, the inner surface of the third handle portion, and the finger surface cooperate to define a quadrilateral having radii or rounded edges between each of the straight surfaces.

[0072] The device 212 also has multiple speed settings (preferably 1500 RPM and 2400 RPM, but can be any speed or frequency taught herein). Additionally, while the RPMs are listed as specific numbers, it will be understood by those skilled in the art that the RPMs may vary during use due to manufacturing tolerances. For example, at the 2400 RPM setting, the RPMs may actually vary between 2260 and 2640.

[0073] FIGS. 6-10 illustrate some of the internal and external components included in the processing device 212 (208 and 210) shown in FIGS. 1-5 and 11-16. As shown in FIG. 6, the percussive massage device 212 has a housing 101 comprised of a first housing half and a second housing half 103. An outer cover 213 and a top cover 215 are received in and connected to the first and second housing halves 103 via tabs 105 or other mechanisms or attachment methods (e.g., threaded fasteners, clips, adhesives, sonic welding, etc.). The percussive massage device 212 also includes a tambour door 217, a battery 114, an internal suspension ring 219, and a rotatable housing 44 (having a first rotatable housing half 44a and a second rotatable housing half 44b) that houses a gearbox 404.

[0074] As shown in FIG. 7 , the device includes a pinion coupling assembly 216 disposed between the motor and the pinion shaft or shaft gear 117 (disposed on the shaft or pinion shaft 116). The pinion coupling assembly 216 is used to couple the motor to the gearbox to eliminate radial movement and fully transmit torque with minimal vibration and noise. The pinion coupling assembly 216 preferably includes three separate components: a lower connector 218, a cross coupling 220, and an upper connector 222. In a preferred embodiment, the lower connector 218 includes a body portion 218a defining a central opening 218b that receives the motor shaft 248 and first and second outwardly extending lower connector arms 218c. The upper connector 122 includes a body portion 222a defining a central opening 122b that receives the pinion shaft 117 and first and second outwardly extending upper connector arms 222c. Preferably, cross coupling 220 has radially extending ribs 220a defining channels 220b. First and second lower connector arms 218c and first and second upper connector arms 222c are sized and shaped to be received in channels 220b so as to operably engage the radially extending ribs. During use, motor shaft 248 rotates the pinion coupling assembly, which in turn rotates pinion shaft 117. These components cooperate to reduce noise and vibration. In a preferred embodiment, the lower and upper connectors are constructed from plastic, and the cross coupling is constructed from elastomer. In a preferred embodiment, cross coupling 220 is constructed from rubber having a hardness that provides isolation from vibrations generated by the motor while maintaining strength and efficiently transmitting torque (without significant energy dissipation). However, the materials are not a limitation of the present invention.

[0075] In a preferred embodiment, pinion shaft 116 is received in and extends from bearings 224 and 225. Preferably, bearing 224 comprises a ball bearing (which provides radial support) and bearing 225 comprises a needle bearing (which provides radial support but can withstand higher temperatures). Pinion coupling assembly 216 is connected to motor 106 and is housed in motor mount 250 through which motor shaft 248 extends. Motor mount 250 is connected to gearbox mount 252, as shown in FIG. 9.

[0076] As shown in FIGS. 7-9 , the gearbox 404, in one embodiment, includes the gear member 304 and the reciprocator or push rod 230 / 310. Preferably, the gear member 304 has a shaft 246 extending therefrom to which the reciprocator 310 is connected. The gearbox 404 can provide a mounting point for the gear member 304 and the reciprocator 310. The gearbox 404 can limit the movement of the gear member 304 and the reciprocator to a particular direction or axis of rotation. The gearbox 404 can be attached to the housing 101. In some embodiments, the gearbox 404 is decoupled from the housing 101 by one or more compliant damping blocks 402.

[0077] As shown in Figures 6 and 8, in a preferred embodiment, a rubber cover may be provided to prevent the gearbox from transmitting vibrations to the housing. Additionally, an inner suspension ring 219 isolates gearbox vibrations from the handle and processing structure. Preferably, ring 219 is constructed of an elastomer and acts as a cushion to dampen vibrations between the rotating housing and housing 101. In a preferred embodiment, inner suspension ring 219 surrounds the outer radial surface of body portion 62 (see seating surface 523 in Figure 8).

[0078] In one embodiment, the rotation of the actuation output or shaft 108 may be selectively locked and unlocked by a user. For example, a user may unlock the rotation of the shaft 108, rotate the actuation output 108 to a desired position relative to the housing 101, lock the rotation of the actuation output 108, and operate the reciprocating device 100. FIG. 8 shows the components that enable rotation of the rotatable housing 44 along with the push rod assembly 108 and associated components. Button 515 has radially extending teeth 515a and is outwardly biased by spring 519 that surrounds and seats on spacer 518 (preferably composed of foam). Spring 519 seats against damping members 520 and 517, preferably composed of rubber, to damp vibrations of spring 519. The assembly also includes a gearbox cover 525 and a damping ring 521. The button 515 is biased outward by a spring 519 to a position that engages the teeth 515a with the teeth 516a that define the hoop 516 connected to the housing 101. Preferably, the hoop 516 has an inner plastic ring 516b and an outer plastic ring 516c that sandwich a rubber ring 516d to help dampen vibrations and reduce noise. The button 515 is movable between a first position in which the teeth 515a engage with the teeth 516a and a second position in which the teeth 515a do not engage with the teeth 516a. When the button 515 is in the first position, the rotating assembly 47 cannot rotate. When the button is pressed to the second position, the teeth 515a disengage from the teeth 516a, thereby allowing the entire rotating assembly 47 to rotate. The rotating housing 44 has a body portion 62 disposed within the housing and an arm portion 64 that extends outside the housing through the rotation space 60. Arm portion 64 rotates in a rotation space 60 defined in housing 101. As shown in Figure 2, in a preferred embodiment, equipment 212 has a tambour door 217 that opens in rotation space 60 when the rotating assembly moves from the position shown in Figure 1 to the position shown in Figure 2. Tambour door 217 covers slot 214. As shown in Figure 2, arm cover 524 covers arm portion 64 of rotating housing 44.

[0079] As shown in FIG. 9 , the gearbox housing 404 has a clearance slot 214 defined for the push rod assembly 108. The slot 114 is provided to allow the push rod assembly 108 to move freely while the rotating housing 44 articulates. The clearance slot 214 has a first end 214 a and a second end 214 b. As shown in FIG. 9 , the push rod assembly 108 extends through the clearance slot 210. It will be appreciated that the push rod assembly 108 moves within the clearance slot 210 from its first end to its second end as the rotating housing 44 rotates from a first position to a second position.

[0080] As shown in Figures 8-10, in a preferred embodiment, the push rod assembly or output shaft 108 has two halves or rods with an adapter member 226 to help reduce noise and vibration. The adapter member 226 decouples vibrations generated in the gearbox and prevents them from being transmitted down the shaft to the treatment structure. The adapter member 226 may have anti-rotation tabs to protect the push rod from torque applied by the user during use. The first rod portion 230 (push rod or reciprocator 310) of the output shaft 108 has an opening 232 at its end that accepts a pivot pin 234. The connection between the first rod portion 230 and the adapter member 226 includes a bushing 227 with the pin 234 and an elastomeric material for vibration damping. The end of the first rod portion 230 with the opening 232 is received in a pocket 229 in the adapter member 226. The pin 234 extends through an opening in the sidewall of the adapter member 226, the bushing 227, and the opening 232 to secure the first rod portion 230 to the adapter member 226. The adapter member 226 has a protrusion 231 that extends to be received in an opening 233 in the end of the second rod portion 236 to connect the adapter member 226 to the second rod portion 236. In another embodiment, the end of the second rod portion 236 can be received in the opening in the adapter member 226. In use, the size of the opening in the upper side of the pocket 229 allows the first rod portion 231 to move side to side as the opening 232 pivots on the pin 234 and the first rod portion 231 reciprocates. This translates to linear reciprocating motion of the second rod portion 236. Because the bushing 227 includes at least some elastomeric material, vibrations are damped (noise is reduced) as the push rod assembly 108 reciprocates.

[0081] A ring 526 seats on and surrounds the bottom of arm portion 64 to help hold first housing half 44a and second housing half 44b together (see seat 64a in FIG. 8). A washer or guide member 527 is received in rotating housing 44 to provide stability and a path for the reciprocating push rod assembly or output shaft 108.

[0082] 9, in this embodiment, the first rod portion 230 or push rod assembly 108 extends through the clearance slot 210. It is understood that the term push rod assembly includes any of the embodiments described herein and can have a shaft with an adapter member that allows for pivoting between the two halves or can have a single shaft that does not include pivoting.

[0083] 9-10, in a preferred embodiment, the male connector 110 has alignment tabs 497 on each ball that mate with slots in the female opening. These tabs 497 aid in proper alignment with the treatment structure. See U.S. Patent Application Publication No. 2019 / 0017528, which is incorporated herein by reference in its entirety.

[0084] FIGS. 11-16 illustrate an embodiment of a percussive massage device similar to the percussive massage device 212 described above, but without a rotating assembly. The device 208 shown in FIGS. 11-14 is commercially referred to as G3. The device 210 shown in FIGS. 15-16 is commercially referred to as LIV. As shown in FIG. 13, in a preferred embodiment, the switch 104 has associated switch electronics 575. The switch electronics 575 may include a printed circuit board (PCB) and other components, allowing the switch 104 to activate the motor 106, change the motor's speed, and turn the device on and off, among other tasks. As shown in FIG. 13, in a preferred embodiment, the motor 106 is housed in the third handle portion 147, the battery 114 is housed in the second handle portion 145, and the switch electronics 575 is housed in the first handle portion 143. This configuration also applies to devices 210 and 212. 14 shows a cushion member 577 that surrounds gearbox 404 and helps to dampen and reduce noise and vibration generated by the gearbox components.

In another embodiment, the voltage of the motor 713 is measured or detected using a separate series of electronic components or a stand-alone device and input to a microprocessor for use in a method to indicate force on the percussive massage device.

[0104] FIG. 21 is a flow chart illustrating a method 800 for detecting a force applied by a percussive massage device according to a preferred embodiment. In step 802, a voltage magnitude V is obtained. In one embodiment, the voltage magnitude V is an analog voltage obtained by using the circuit disclosed in FIG. 17. In this circuit, a block curve signal from the motor 713 (i.e., a Hall Effect sensor) is simulated in the circuit as a current using a resistor R placed in parallel with the microcontroller unit 701. In other embodiments, a voltage corresponding to the current operating speed of the motor 713 may be generated in various other ways. The voltage magnitude V can be input to the microcontroller unit 701, which converts the analog voltage to a digital voltage using an analog-to-digital converter such as that implemented in an STM32F030K6 microcontroller unit. The STM32F030K6 microcontroller unit converts the analog voltage magnitude into a digital code corresponding to a 12-bit ADC (i.e., 0 to 4096). The digital code represents a voltage magnitude corresponding to the original voltage magnitude V obtained.

[0105] In step 804, a lookup table relating voltage V to force magnitude F is generated. In one embodiment, the lookup table is generated using method 900 for generating a lookup table relating voltage to force. For example, force magnitude F may be expressed in pounds of force. In an alternative embodiment, force magnitude F may be expressed in newtons of force.

[0106] In step 806, the force magnitude F corresponding to the voltage magnitude V is displayed on the percussive massage device having the force meter 700. In one embodiment, a series of LED lights may be used to represent different amounts of force being applied by the percussive massage device having the force meter 700. Thus, as the force magnitude F increases, more LEDs in the series of LED lights are illuminated. Preferably, the series of LED lights consists of 12 LED lights.

[0107] 22 is a flow diagram illustrating a method 900 for generating a lookup table relating voltage to force. In step 902, the maximum magnitude of the force F MAX Determine F MAX The magnitude of F may be determined by assessing the maximum desired force to apply using a percussive massage device with a force meter 700. As an example, F MAX is 60 pounds of force.

[0108] In step 904, the maximum magnitude of the voltage V MAX Determine V MAX The magnitude of V may be determined by assessing the maximum theoretical voltage change possible by the percussive massage device with force meter 700. MAX is 1.8 volts.

[0109] In step 906, F MAX is divided into equal increments. Using the example above from step 902, a 60 pound force is divided into 60 1 pound increments.

[0110] In step 908, V MAX is divided into increments of the same amount as determined above in step 906. So, using the above example from step 904, 1.8 volts would be divided into 60 0.3 volt increments.

[0111] In step 910, a look-up table (LUT) is generated that relates increments in pounds of force to increments in voltage. This necessarily creates a linear relationship between force and voltage. Figure 23 is a graph plotting the LUT for use by the force detection method of Figure 21 generated using the specific example identified in Figure 22. The graph shows the forces calculated using method 900.

[0112] A problem may arise in that the theoretical maximum voltage assumption in step 904 of method 900 is inaccurate. The maximum voltage available when using a percussive massage device with force meter 700 may decrease over time. In other words, the voltage of the battery or battery pack may decrease.

[0113] Therefore, a method 1000 for calibrating the LUT generated by method 900 may be advantageous. FIG. 24 is a flow chart illustrating the method 1000 for calibrating a LUT. In step 1002, a battery pack voltage BV is acquired. In one embodiment, the battery pack voltage magnitude BV is an analog voltage acquired by using the circuit disclosed in FIG. 19. In the circuit, the battery pack voltage magnitude BV may be input to a microcontroller unit 701, which converts the analog voltage to a digital voltage using an analog-to-digital converter such as that implemented in an STM32F030K6 microcontroller unit. The STM32F030K6 microcontroller unit converts the analog voltage magnitude to a digital code corresponding to a 12-bit ADC (i.e., 0 to 4096). The digital code represents a voltage magnitude corresponding to the acquired original battery pack voltage magnitude BV.

[0114] In step 1004, V MAX to the BV output of the magnitude of the actual battery voltage. For example, a decrease from 1.8 volts to 1.74 volts would result in a decrease of 0.6 volts. In step 1006, the LUT linear correlation is MAX 25 is a graph plotting the LUT calculated by method 1000 against the LUT calibrated using method 1000. The LUT resulting from method 1000 represents the calibrated force rather than the calculated force.

[0115] 26 is a flow diagram illustrating a method 1100 for calibrating the LUT. Method 1100 may be performed after method 900 or completely separate from method 900. In step 1102, the battery pack voltage BV is measured. In one embodiment, the measurement is performed without applying force from the percussive massage device with force meter 700. In one embodiment, the battery pack voltage BV is measured using an external voltmeter. In another embodiment, the battery pack and / or microcontroller unit 701 has a built-in solution for directly measuring the battery pack voltage BV.

[0116] In step 1104, a display of the percussive massage device having a force meter 700 that displays the force magnitude F is read to determine the force magnitude F that corresponds to the measured battery pack voltage BV.

[0117] In step 1106, a force meter is used to measure the actual force being applied. In one embodiment, the force meter is a push / pull force meter. Measuring the force directly allows for calibration of the LUT by comparing the indicated force magnitude F to the measured actual force. In step 1108, the LUT is updated with the calibrated force corresponding to the measured battery pack voltage BV. After step 1108, steps 1102-1106 are repeated for each successive voltage increment. In the embodiment shown in accordance with method 900, steps 1102-1106 are repeated for each 3 volt increment. FIG. 27 is a graph plotting the LUT calculated by method 1100 after all 3 volt increments have been updated.

[0118] 28 is a flow chart illustrating a method 1200 for detecting a force applied by a percussive massage device according to a preferred embodiment. In step 1202, a current magnitude C of the battery pack is obtained. In one embodiment, the current magnitude C is input to the microcontroller unit 701. In step 1204, a voltage magnitude BV of the battery pack is obtained. In one embodiment, the voltage magnitude BV is input to the microcontroller unit 701. In step 1206, power is calculated using the product of C and BV. In one embodiment, the microcontroller unit 701 is configured to calculate power by multiplying C and BV. In step 1208, a lookup table relating a power magnitude P to a force magnitude F is generated. In one embodiment, the lookup table is generated using method 1300 for generating a lookup table relating power to force. For example, the power magnitude P may be expressed in watts. In alternative embodiments, the force magnitude F may be expressed in pounds-force or newtons-force.

[0119] In step 1210, a force magnitude F corresponding to the power magnitude P is displayed on the percussive massage device having the force meter 700. In one embodiment, a series of LED lights may be utilized to depict different amounts of force as it is applied by the percussive massage device having the force meter 700. Thus, as the force magnitude F increases, more LEDs in the series of LED lights are illuminated. Preferably, the series of LED lights consists of 12 LED lights.

[0120] 29 is a flow diagram illustrating a method 1300 for generating a lookup table relating power to force. In step 1302, the maximum magnitude of the power F MAX However, if the total effective power can be calculated, the theoretical maximum power magnitude is not a reasonable assumption. MAX ) may be determined using Equation 1.

number

[0121] Equation 2 may be used to calculate Total EP and then substitute it into Equation 1.

number

[0122] In one embodiment, EP(Battery) is 85%, EP(PCBA) is 95%, and EP(Motor) is 75%. Therefore, using Equation 2, Total EP is 85%*95%*75%=60.5625%.

[0123] In this embodiment, P MAX As shown in Equation 3, the maximum voltage of the battery pack V MAX Max amperage C MAX Then, P MAX Substitute into Equation 1.

number

[0124] In this embodiment, V MAX is 16.8 volts, C MAX is 20 amperes. Therefore, P MAX is 336 watts.

[0125] Now, going back to equation 1, P MAX is 336 watts and Total EP is 60.5625%. MAX is 203 watts.

[0126] In step 1304, the minimum amount of power P MINIt will be recognized by those skilled in the art that no force is applied (i.e., no load) is a force other than zero. Therefore, a 12 watt P MIN Assume that P MIN It is also understood that the value of V corresponds to the rated power at no load. MAX and C MIN It may be derived from

[0127] In step 1306, the maximum magnitude of the force F MAX Determine F MAX The magnitude of F may be determined by assessing the maximum desired force to apply using a percussive massage device with a force meter 700. As an example, F MAX is 60 pounds of force.

[0128] In step 1308, the Total EP MAX In one embodiment, the Total EP MAX , P MIN Start with (12 watts) and divide by 3 watt increments for every pound of force. MAX is 60 lbs of force, is the total desired force output of the percussive massage instrument with Force Meter 700, and the calculated Total EP MAX It will be recognized by those skilled in the art that 60 pounds of force is associated with 189 watts.

[0129] In step 1310, a LUT is generated that relates increments of force in pounds to increments of power in watts. This necessarily creates a linear relationship between force and voltage. Figure 30 is a graph plotting a LUT for use by the force detection method of Figure 28 generated using the specific example identified in Figure 25. The graph shows the force calculated using method 1200.

[0130] Similar to method 900, a problem may arise in that the measured voltage of the battery pack measured in step 1204 of method 1200 is inaccurate. The maximum available voltage may decrease over time as the percussive massage device with force meter 700 is used. In other words, the voltage of the battery or battery pack may decrease.

[0131] 31 is a flow diagram illustrating a method 1400 of calibrating the LUT. Method 1400 may be performed after method 900 or method 1200, or entirely separate from method 900 or method 1200. In step 1402, a current magnitude C of the battery pack is obtained. In one embodiment, the current magnitude C is input to the microcontroller unit 701.

[0132] In step 1404, the battery pack voltage BV is measured. In one embodiment, the measurement is performed without applying force from the percussive massage device with force meter 700. In one embodiment, the battery pack voltage BV is measured using an external voltmeter. In another embodiment, the battery pack and / or microcontroller unit 701 has a built-in solution for directly measuring the battery pack voltage BV. In step 1406, the power is calculated using the product of C and BV. In one embodiment, the microcontroller unit 701 is configured to calculate the power by multiplying C by BV.

[0133] In step 1408, the display of the percussive massage device, which has a force meter 700 displaying the force magnitude F, is read to determine the force magnitude F corresponding to the calculated force. In step 1410, the force meter is used to measure the actual force being applied. In one embodiment, the force meter is a push / pull force meter. Measuring the force directly allows for calibration of the LUT by comparing the displayed force magnitude F to the measured actual force. In step 1412, the LUT is updated with the calibrated force corresponding to the measured power. After step 1412, steps 1402-1410 are repeated for each force or force increment. In the embodiment shown in accordance with method 900, steps 1402-1410 are repeated for each 3-watt increment. FIG. 32 is a graph plotting the LUT calculated by method 1400 after all 3-watt increments have been updated.

[0134] 33-35 illustrate an exemplary percussive massage device 400 embodying features disclosed herein, particularly in FIGS. 17-48 (or FIGS. 1-16). Generally, percussive massage device 400 includes a housing 402, a power source or battery pack 404, a motor 406 disposed within housing 402, and a switch 405 for activating motor 406. The electronics (see printed circuit board 408 in FIG. 34) includes a controller configured to acquire the motor voltage and generate a lookup table relating the voltage to the force applied by the percussive massage device, and a display that displays the magnitude of the force corresponding to the voltage acquired using the lookup table.

[0135] Figures 36-43A show additional views of percussive massage device 400. Figures 36 and 37 are similar to Figures 1 and 1A and show percussive massage device 400 having first handle portion 143, second handle portion 145, and third handle portion 147 that cooperate to define handle portion 149. For descriptions of other reference numbers and features shown in Figures 36-40, see at least the descriptions of Figures 1-5. All of the features and components described above with respect to a percussive therapy device or percussive massage device may be included in percussive massage device 400.

Preferably, the point where the push rod 14 connects to the shaft 16 is offset from the reciprocating path traveled by the distal end 18 of the push rod 14 (and massage attachment 628). The arc or L-shape provides this function. It should be understood that the push rod 14 is designed to transmit force at least partially diagonally or arcuately along its shape rather than perpendicularly, so that the motor can be placed at or near the center of the device, otherwise a protrusion would be needed to offset the motor and keep the shaft centered. The arc allows the push rod 14 to have a close clearance with the motor, as shown in FIGS. 42A and 42B, allowing the external housing to be smaller than similar prior art devices, thus lowering the profile of the device 400. FIG. 42A shows the push rod 14 at the bottom dead center of travel, and FIG. 42B shows the push rod 14 at the top dead center of travel. Preferably, one or more bearings 20 are included at the proximal end of the push rod 14 that connects to the motor to counteract oblique forces and prevent the push rod 14 from contacting the motor 406 as it moves. The bearings 20 are received in the shaft 16, and the threaded fastener 26 is received in a coaxial opening 16a in the shaft 16. The proximal end of the push rod 14 is received in the bearings 20. All of these components are shown in FIG. 43.

The device 400 may also have a thumbwheel or rolling button located near the touchscreen / on / off buttons to allow the user to scroll or navigate through the various functions. Touchscreen 409 for Operating the Device. In the embodiment shown in FIG. 33, the device 400 has a touchscreen 409, a center button 404 for turning the device on and off, and a ring / rocker button 447 that provides the ability to scroll left and right (e.g., for preset operations as described herein) and up and down (e.g., to control speed or frequency). The screen can be a non-touchscreen or can simply be used for display purposes.

For example, the stroke can be or be varied between approximately 8 and 16 mm. In another embodiment, the stroke can be varied up to 25 mm or more. Amplitude / stroke variability can also be part of the routines, presets, or protocols described herein. For example, the device can have a mechanical switch that allows the eccentricity of the connector to be changed (e.g., between 4 mm and 8 mm). This mechanism can have a push button and a slider. The pin structure has a spring that can return to a locked position.

[0140] Similar to the percussive massage devices 208, 210, and 212 described above, in a preferred embodiment, the device 400 includes a number of damping components, such as elastomers, and a damping vibration section to keep the device relatively quiet. For example, as shown in FIG. 43, the device 400 includes a damping ring 426 (similar to the inner suspension ring 219) that surrounds the rotatable housing 44 (having a first rotatable housing half 44a and a second rotatable housing half 44b) and helps to dampen vibration sounds between the rotatable housing and the outer housing 101.

[0141] As shown in FIGS. 43 and 43A, the device 400 also preferably includes a motor mount 24 that secures the motor 406 in place and is secured to the housing 101 / 402. The motor 406 has a receiving member 28 with three projections 30 (which may number between 1 and 10) that are received in projection openings 32 defined in the motor mount 24 (in the first wall 38). A flange 34 extending from the motor mount 24 helps to hold the projections 30 in place. The motor 406 is preferably secured to the motor mount 24 via a threaded fastener or the like. The motor shaft 21 extends into a motor mount interior 36 defined between the first and second walls 38 and a side surface 40 that extends partway around the circumference. The counterweight assembly 17, the proximal end of the push rod 14, and associated components for converting rotation of the motor shaft 21 into reciprocating motion are located within the motor mount interior 36. The push rod 14 extends downward from within the motor mount through a push rod opening 42 in the side surface 40. In a preferred embodiment, the motor mount 24 is directly connected to the housing 402 / 101 via a fastener 46 secured to a mounting member 48 of the housing (see FIG. 43A). The term push rod assembly, as used herein, is understood to include any or a combination of the components discussed herein that extend from the rotatable motor shaft 21, etc., that provides reciprocating motion and has an attachment at its distal end, such as the push rod 14, output shaft 108, reciprocator 310, and second rod portion 236. The push rod assembly includes a male connector 110 (and any associated components) or any other connector at the end of the reciprocating component that allows for connection of an attachment used for massage or treatment.

[0142] Preferably, the device can be wirelessly charged. Figure 34 shows the wireless power receiver 22 located in the third handle portion 147. In another embodiment, the wireless power receiver 22 can be located in either the first handle portion 143 or the second handle portion 145 or in the head portion 12.

[0143] In a preferred embodiment, device 400 can be associated with and operated by an app or software running on a mobile device such as a phone, watch, or tablet (or any computer). The app can connect to device 400 via Bluetooth or other wireless connection protocols. The app can have any or all of the following functions: Additionally, any of the functions described herein can be added directly to the device's touchscreen / scroll wheel or button(s). If the user walks or is too far away from the device, the device will not function or operate. The device can be turned on and off using the app and the device's touchscreen or buttons. The app can control variable speed (e.g., anywhere between 1750 and 3000 RPM). A timer can be implemented to stop the device after a predetermined time.

[0144] In a preferred embodiment, the device has different treatment protocols or routines associated with it, such as via an app or touchscreen and other function buttons. During the routine, the device can change various aspects or outputs of the device or make changes based on time, speed (frequency), amplitude (strokes), arm position, force, temperature, grip (i.e., the handle portion for grasping), attachment (e.g., cone, ball, damper, etc.), and body part. The device can also prompt the user (via the app, touchscreen, haptic feedback, or audio via speaker) to make these changes at specific points during the routine, e.g., arm position, grip, attachment changes, body part changes. Those skilled in the art will understand that depending on the specific design of the device, one or more of these outputs may be applicable, while in other devices all of the described options may be applicable.

[0145] When a protocol is selected, the device executes a pre-programmed routine. For example, the device may operate at a first RPM for a first period of time, followed by a second RPM for a second period of time, and / or at a first amplitude for a first period of time, followed by a second amplitude. The routine may also include prompts (e.g., haptic feedback) to notify the user when to move to a new body part. These routines or treatments may relate to recovery, increased blood flow, performance, etc., and each may have a pre-programmed routine or protocol. These routines may also help promote certain activities, such as sleep, interval training, stairs, post-running, post-workout, recovery, wellness, post-core exercise, and high-intensity (plyometric) training, among others. The routines may also help provide relief and recovery from ailments such as plantar fasciitis, "tech neck," muscle spasms, jet lag, sciatica, carpal tunnel, knots, and shin splints, among others. The routine can prompt or instruct the user to switch the position of the attachment (e.g., attachment 628 shown in FIG. 40) or the arm or rotating housing. The prompt can include a sound, haptic feedback (e.g., vibration of the device or mobile device), textual instructions, or a visual representation such as a graphic or image on the app or touchscreen. For example, the app may instruct the user to start with the ball attachment with the arm in position 2. The user then presses start, and the device runs at a first frequency for a predetermined time. The app or device then prompts the user to begin the next step of the routine, instructing the user to change to the cone attachment and place the arm in position 1 (e.g., see arm positions in FIG. 38). The arm can have any number of positions, e.g., positions 1-10, or positions 1-3, or positions 1-2. FIGS. 38-40 show the arm in three different positions. The user presses start again, and the device runs at a second frequency for a predetermined time.A protocol can be divided into steps, and at each step, various outputs are predetermined or specified.

[0146] In a preferred embodiment, device 400 includes housing 402 (or 101), power source 114, motor 406 disposed in housing 402, switch 405 (which may be either touchscreen 409, rocker button 447, button 404, or any other switch or button) for activating motor 406, and routine controller 630. Device 400 is configured to connect with attachment 628. The attachment may be, for example, attachment 628 shown in FIG. 38. The attachment is attached to male connector 110 such that shaft or push rod assembly 108 moves the attachment relative to one another according to a specified amplitude. For example, the amplitude is shown in FIGS. 42A and 42B, where FIG. 42A shows the attachment in a maximum extended position and FIG. 42B shows the attachment in a minimum extended position. The distance between the maximum extended position and the minimum extended position may define the amplitude, in one embodiment.

[0147] The attachment 628 can be a variety of attachments configured to provide therapeutic relief to specific parts of the body. For example, the attachment 628 can be a standard ball attachment intended for global use on both large and small muscle groups (see U.S. Patent Application Publication No. 29 / 677,157, incorporated herein by reference in its entirety). The attachment 628 can be a cone attachment for pinpoint muscle treatment, trigger points, and small muscle areas such as the hands and feet (see U.S. Patent Application Publication No. 849,261, incorporated herein by reference in its entirety). The attachment 628 can also be a damper attachment used for global use as well as tender or bony areas (see U.S. Patent Application Publication No. 29 / 676,670, incorporated herein by reference in its entirety). The attachment 628 can also be a wedge attachment for use on the shoulder blades and IT bands (see U.S. Patent Application Publication No. 29 / 677,016, which is incorporated herein by reference in its entirety) used for "rubbing" and "flushing" motions to help flush lactic acid from the muscles. The attachment 628 can also be a large ball for large muscle groups such as the glutes and quadriceps (see U.S. Patent Application Publication No. 29 / 677,016, which is incorporated herein by reference in its entirety). The attachment 628 can also be a thumb attachment for use on trigger points and the lower back (see U.S. Patent Application Publication No. 850,639, which is incorporated herein by reference in its entirety). The attachment 628 can also be a supersoft attachment designed to provide therapeutic relief to sensitive areas, including bones (see U.S. Patent Application Publication No. 29 / 726,305, which is incorporated herein by reference in its entirety). Those skilled in the art will recognize that the attachments described herein are non-limiting and that other configurations of attachments, including various materials and shapes, may be utilized in accordance with this embodiment. Spherical attachments, bifurcated attachments, flat attachments, or attachments of other shapes are all within the scope of the present invention.

[0148] Routine controller 630 is configured to execute routines in association with one or more specified protocols. Routine controller 630 may be, for example, microcontroller unit 701 shown in FIG. 17. Routine controller 630 may also be a stand-alone microcontroller separate from microcontroller 701. Routine controller 630 may step through the various steps of a particular protocol designed to target specific muscle groups and provide a particular therapeutic effect, as described herein.

[0149] FIG. 44 is a table illustrating an example of a protocol according to a preferred embodiment. Protocol 1 is divided into four steps, each representing a specified time, speed, amplitude, attachment, force, temperature, and grip. In Step 1, the device 400 is operated at a speed of 1550 RPM for 30 seconds. A routine controller 630 may be utilized to turn on the percussive massage device and achieve a speed of 1550 RPM for the attachment 628. Those skilled in the art will appreciate that the speed of the attachment 628 is directly proportional to the speed of the motor 406. The amplitude of the percussive massage device is set to 2 according to Protocol 1. This may translate to a specified distance the attachment 628 will travel during use, as described above. Step 1 specifies a damper attachment attached to the device 400, a force of "1" applied by the device 400, and a temperature of 21° C. applied to the attachment.

[0150] Those skilled in the art will appreciate that the force applied by device 400 depends on the pressure applied by the user when pressing the attachment against the person's body part. As described more fully herein, the force applied by device 400 may be a target force. In embodiments in which the user provides pressure to apply a particular force to the person's body part, routine controller 630 may adjust the output of device 400 to ensure that the force actually applied by the attachment is the target force. Routine controller 630 may be configured to provide feedback to the user to increase or decrease the pressure on the person's body part to meet the target force. Each of these embodiments is applicable to each step of a given protocol, including steps 2-4 below and steps 1-4 of the protocol shown in FIG. 45.

[0151] Step 1 specifies that grip 1 is used to operate the instrument 400. Grip 1 may be, for example, the grip shown on the first handle portion 143 shown in FIG. 39, also referred to as the "normal" or "standard" grip. Grip 2 may be, for example, the grip shown on the third handle portion 147 shown in FIG. 40, also referred to as the "reverse" grip. An "inverse" grip may also be used on the third handle portion 147 (not shown). Grip 3 may be, for example, the grip shown on the second handle portion 145 shown in FIG. 41, also referred to as the "base" grip.

[0152] In step 2, protocol 1 specifies that device 400 is to be operated for 15 seconds at 2100 RPM, an amplitude of "3", a force of "3", and a temperature of 26° C. Step 2 specifies that small ball attachment 628 is to be used and that grip 1 is to be used to operate device 400. Thus, step 2 specifies that the damper attachment of step 1 should be replaced with the small ball attachment, but the same grip is to be used.

[0153] In step 3, protocol 1 specifies that device 400 is to be operated for 30 seconds at 2200 RPM, an amplitude of "1", a force of "3", and a temperature of 29° C. Step 3 specifies that damper attachment 628 is to be used and that grip 1 is to be used to operate device 400. Thus, step 3 specifies that the small ball attachment of step 2 should be replaced with a damper attachment, but the same grip is to be used.

[0154] In step 4, Protocol 1 specifies that device 400 is to be operated at 2400 RPM, an amplitude of "4," a force of "2," and a temperature of 32°C for 45 seconds. Step 4 specifies that a large ball attachment is to be used and that grip 1 is to be used to operate device 400. Thus, step 4 specifies that the damper attachment of step 3 should be replaced with a large ball attachment, but the same grip is to be used. It is understood that Protocol 1 is provided as an example to the reader of the many different outputs that can be provided or varied during the course of countless treatment protocols that can be developed. Furthermore, it is understood that any one or more of the outputs may be part of a protocol or routine, and that any of the outputs discussed herein may be omitted. For example, a protocol may include time and velocity only, time, velocity and force only, time, velocity and grip only, or any other combination of the outputs described herein.

[0155] 45 is a table illustrating an example of a "shin splints" protocol according to a preferred embodiment. Like Protocol 1, the shin splints protocol is divided into four steps, each with a specified time, speed, amplitude, attachment, force, temperature, and grip, but also specifying the specific arm position and body part to apply the attachment to. In Step 1, the device 400 is operated for 1 minute at a speed of 1500 RPM, an amplitude of "1," a force of "2," and a temperature of 21°C. Step 1 also specifies the use of the damper attachment 628 and the operation of the device 400 using grip 2 ("reverse") on the right shin.

[0156] Step 1 specifies that the arm positions 632, 634, and 636 to be used are arm position 1. Those skilled in the art will appreciate that the arm position numbers (e.g., 1, 2, 3, 4, etc.) are predetermined arm positions intended for use during a particular protocol. The part of the body to which the attachment 628 is applied is one factor in determining the optimal arm position. However, the arm position may be determined by the user and is not required to implement a protocol. As shown in FIG. 39, a "standard" grip may be utilized at arm position 632 to apply to a particular part of the body. As shown in FIG. 40, a "reverse" grip may be utilized at arm position 634 to apply to a particular part of the body. As shown in FIG. 41, a "base" grip may be utilized at arm position 636 to apply to a particular part of the body. Those skilled in the art will appreciate that the arm positions 632, 634, and 636 combined with particular grips 143, 145, and 147 may vary depending on the application. Those skilled in the art will appreciate that the configuration of the arm positions for the instrument 400 will depend on the particular device. For example, certain devices may allow the user to adjust the arm position while other devices may not allow the user to adjust the arm position, otherwise this procedure does not apply. In other embodiments, this step may be performed during the execution of a step of a particular protocol.

[0157] In Step 2, the shin splint protocol specifies operating the device 400 at 1500 RPM, amplitude of "1", force of "2", and temperature of 21° C. for 1 minute. Step 2 specifies using damper attachment 628 and operating the device 400 using grip 2 ("reverse") for the left shin. Thus, Step 2 uses the same attachment, grip, and arm position as Step 1, but applies to the other shin.

[0158] In step 3, the shin splint protocol specifies that the device 400 is to be operated at 2000 RPM, an amplitude of "3", a force of "3", and a temperature of 24° C. for 1 minute. Step 3 specifies that the device 400 is to be operated using the damper attachment 628 and with grip 3 ("base") at arm position 1 on the right calf. Thus, step 3 requires the user to change grip from "reverse" to "base", but using the same attachment and arm position.

[0159] In step 4, the shin splint protocol specifies operating the device 400 at 2000 RPM, amplitude of "3", force of "3", and temperature of 24° C. for 1 minute. Step 4 specifies using damper attachment 628 and operating the device 400 using grip 3 ("base") for the left calf. Thus, step 4 uses the same attachment, grip, and arm position as step 1, but applies to the other calf.

[0160] FIG. 46 is a series of flow diagrams (FIGS. 46A, 46B, 46C) illustrating a method 1500 of executing a routine for a percussive massage device.

[0161] 46A is a flow diagram illustrating an exemplary protocol initiation. In step 1502, Protocol 1 is initiated. Protocol 1 may be, for example, Protocol 1 shown in FIG. 44 or the "Thin Splints" protocol shown in FIG. 45. Those skilled in the art will understand that Protocol 1 shown in FIG. 44 does not include all outputs specified in the Thin Splints protocol shown in FIG. 45, and therefore, not all steps of method 1500 apply to Protocol 1 shown in FIG. 44.

[0162] In step 1504, the user is prompted to set the arm position to a designated arm position 632, 634, 636. The user may be a person using the device 400 on their own body or on another person's body. The designated arm position 632, 634, 636 in the shin splints protocol is, for example, arm position 1.

[0163] In step 1506, the user is prompted to use a designated grip or handle portion 143, 145, 147 of the device 400. The designated grip in the shin splints protocol is, for example, the third handle portion 147. As described herein, the grip may be changed depending on the particular protocol or step.

[0164] In step 1508, the user is prompted to attach the specified attachment to the device 400. As described herein, the attachment may vary depending on the particular protocol or step.

[0165] In step 1510, the method determines whether the arm positions 632, 634, 636 and grip positions 143, 145, 147 are properly configured and whether the attachment 628 is attached. Step 1510 may include prompting the user via haptic feedback, an application interface, or a touchscreen (among other types of prompts) asking the user to proceed when the proper arm position, grip, and attachment are ready. In other embodiments, the device 400 may detect that the arm position and grip are proper and that the attachment is attached before automatically proceeding. In one embodiment, step 1510 is repeated until the arm position, grip, and attachment are ready.

[0166] FIG. 46B is a flow diagram illustrating exemplary step 1 of the protocol, which continues method 1500 where FIG. 46A left off.

[0167] In step 1512, step 1 of the protocol is started, for example step 1 shown in Figures 44 and 45.

[0168] In step 1514, method 1500 applies a specified duration (T1) during which device 400 is activated, attachment speed, attachment amplitude, attachment force, and attachment temperature. In one embodiment, one or more of these outputs of device 400 are applied. These outputs may be applied by routine controller 630. Those skilled in the art will appreciate that applying some of these outputs does not require the user to place device 400 on a body part. For example, duration, speed, amplitude, and temperature do not necessarily depend on the user applying pressure to the body part. On the other hand, the force applied by attachment 628 requires the user to apply pressure to the body part to reach a target force (or target force range). Furthermore, the temperature may vary depending on whether and to which body part attachment 628 is applied. Therefore, the temperature needs to be adjusted during application of attachment 628 to reach the desired temperature predetermined by the protocol. In another embodiment, the temperature may be adjusted by the user.

[0169] After time period T1, the user may be prompted to change the attachment 628, arm positions 632, 634, 636, and / or grip positions 143, 145, 147. These outputs must be implemented before starting step 2 of the protocol. In the shin splints protocol shown in FIG. 45, the attachment 628, arm positions 632, 634, 636, and grip positions 143, 145, 147 remain the same. In step 1516, after time period T1, the user is prompted to set the arm positions to the designated arm positions 632, 634, 636. The user may be a person using the device 400 on their own body or another person's body.

[0170] In step 1518, the user is prompted to use the designated grips 143, 145, 147 on the device 400. As described herein, the grips may be changed depending on the particular protocol or step.

[0171] In step 1520, the user is prompted to attach a designated attachment 628 to the device 400. As described herein, the attachment 628 may vary depending on the particular protocol or step.

[0172] In step 1522, the method determines whether arm positions 632, 634, 636 and grip positions 143, 145, 147 are properly configured and whether attachment 628 is attached. This step, and all other similar steps, are optional. Step 1522 may include prompting the user via haptic feedback, an application interface, or a touchscreen (among other types of prompts) to prompt the user to proceed to the next step in the routine and / or to continue when the proper arm position, grip, and attachment are ready. In other embodiments, device 400 may detect that the arm position and grip are proper and that an attachment is attached before automatically proceeding. In one embodiment, step 1522 is repeated until the arm position, grip, and attachment are ready.

[0173] FIG. 46C is a flow diagram illustrating exemplary step 2 of the protocol, which continues method 1500 where FIG. 46B left off.

[0174] Step 2 of the protocol begins in step 1524. Step 2 is, for example, step 2 shown in Figures 44 and 45.

[0175] In step 1526, method 1500 applies a specified duration (T2) during which device 400 is activated, attachment speed, attachment amplitude, attachment force, and attachment temperature. In one embodiment, one or more of these outputs of device 400 are applied. These outputs may be applied by routine controller 630. Those skilled in the art will appreciate that applying some of these outputs does not require the user to place device 400 on a body part. For example, duration, speed, amplitude, and temperature do not necessarily depend on the user applying pressure to the body part. On the other hand, the force applied by attachment 628 requires the user to apply pressure to the body part to reach the target force. Furthermore, the temperature may vary depending on whether and to which body part attachment 628 is applied. Therefore, the temperature needs to be adjusted during application of attachment 628 to reach the desired temperature predetermined by the protocol. In another embodiment, the temperature may be adjusted by the user.

[0176] After time period T2, the user may be prompted to change the attachment 628, arm positions 632, 634, 636, and / or grip positions 143, 145, 147. These outputs must be implemented before starting step 3 of the protocol. In the shin splints protocol shown in FIG. 45, the attachment 628, arm positions 632, 634, 636, and grip positions 143, 145, 147 remain the same, but the grip positions 143, 145, 147 are adjusted to a base grip. In step 1528, after time period T2, the user is prompted to set the arm positions to the specified arm positions 632, 634, 636. The user may be a person using the device 400 on their own body or another person's body.

[0177] Thus, steps 1528-1534 are performed substantially identically to steps 1516-1522. After step 1534, steps 3-4 begin substantially identically to steps 1-2. For example, steps 3 and 4 may be steps 3 and 4 of Protocol 1 shown in FIG. 44 or the Shin Splints Protocol shown in FIG. 45. Furthermore, step 1534 may be omitted for devices in which the grip, arm position, or attachments cannot be detected by the device. In this embodiment, the predetermined protocol simply moves from step 1 to step 2, prompting the user to make changes (whether or not the user actually makes the changes).

[0178] As an alternative to Figure 46C, Figure 46D is a flow diagram illustrating alternative step 2 of the protocol. In alternative step 2, the force meter is calibrated.

[0179] Steps 1536 to 1538 are executed in substantially the same manner as steps 1524 to 1526 in step 2 described above.

[0180] In step 1540, the force being applied by the attachment 628 is monitored. In the embodiment shown in Figure 46D, the method 1500 utilizes a force meter 700 to monitor the actual force being applied by the user.

[0181] In step 1542, the force is displayed to the user. In one embodiment, the force is displayed in an application interface 1584, such as a graphical user interface. In other embodiments, the application interface 1584, touch screen 1582, OLED screen 711, etc. may be used individually or in combination to display the force.

[0182] In step 1546, the user is prompted to increase or decrease the force applied to the body part according to the protocol specified during T2. FIG. 48 illustrates a touchscreen 1582 with an exemplary embodiment of a force display. A force display 1590 illustrates an exemplary embodiment of step 1546. The force display 1590 shows a series of force measurements during the "Right Biceps" step of the protocol. A force display prompt 1592 is used to display a message to the user, such as "Optimal Pressure: Well Done," when the force applied by the attachment 628 matches or corresponds to a target force predetermined by the protocol. In this embodiment, the force display prompt 1592 may recite "Increase Pressure," or the like, if the measured force applied by the attachment 628 is lower than the target force predetermined by the protocol. Consequently, if the measured force applied by the attachment 628 is higher than the target force predetermined by the protocol, the force display prompt 1592 may recite "Decrease Pressure," or the like. In this case, the user may adjust the pressure they are applying to the body part to increase or decrease the pressure according to the force display prompt 1592 so that the measured force is equal to or approximately equal to the target force.

[0183] After time period T2, the user may be prompted to change the attachment 628, arm positions 632, 634, 636, and / or grip positions 143, 145, 147. These outputs must be implemented before starting step 3 of the protocol. In the shin splints protocol shown in FIG. 45, the attachment 628, arm positions 632, 634, 636, and grip positions 143, 145, 147 remain the same, but the grips 143, 145, 147 are adjusted to the base grip. In step 1528, after time period T2, the user is prompted to set the arm positions to the specified arm positions 632, 634, 636. The user may be a person using the device 400 on their own body or another person's body.

[0184] Therefore, steps 1548 to 1554 are performed in substantially the same manner as steps 1516 to 1522. After step 1554, steps 3 and 4 are started in substantially the same manner as steps 1 and 2. For example, steps 3 and 4 may be steps 3 and 4 of protocol 1 shown in FIG. 44 or steps 3 and 4 of the shin splint protocol shown in FIG. 45.

[0185] 47 is a diagram of an example embodiment of an application interface 1584. At the top of the interface 1584, a protocol field 1556 is displayed to the user. In this embodiment, the protocol field 1556 is "Tech Neck." The protocol title 1556 also indicates the overall duration of the protocol.

[0186] The next portion of interface 1584 shows the step fields 1558-1568 of the protocol that are displayed to the user. In this embodiment, the step fields identify the title of the step and the duration of the step. For example, the title of step field 1558 is "Right Biceps" (where treatment occurs) and the duration of operation is "0:30 minutes."

[0187] The interface 1584 also includes a current step field 1570 that identifies the current step title 1570 , a grip title display 1572 and an attachment title display 1574 .

[0188] Interface 1584 also includes a time display 1576 and a time remaining display 1578 to show the user how much time has elapsed between steps and how much time is remaining in the step.
