[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application No. 62 / 978,774, entitled "Systems And Methods For Providing Oscillatory Motion To An Individual," filed February 19, 2020, which is incorporated herein by reference in its entirety.

[0002] SUMMARY The present disclosure relates to medical devices that transmit reciprocating motion to an individual. [Background technology]

[0003] Many physiological phenomena, such as breathing and heartbeat, follow regular cyclical patterns. These physiological processes often respond to oscillatory stimulation. Human health practitioners have long applied reciprocating pressure and motion to various parts of the body to provide positive physiological outcomes. Other forms of reciprocating motion are known to stimulate physiological outcomes. For example, gentle rocking has long been known to calm babies. In another example, the heart is known to respond to oscillatory motion. Enhanced external counterpulsation is a technique for treating angina pectoris by compressing the extremities with an oscillatory rhythm that matches the heartbeat. In another example, high-frequency oscillatory ventilation of premature infants has been shown to prevent lung damage.

[0004] No matter how efficient, automated devices and systems often cannot match the feel and versatility of a human practitioner, who may adjust the frequency and pressure of reciprocating motions to a patient based on various feedback from the patient. There is a need in the art for better systems for delivering vibratory motion to an individual to induce physiological effects, including reducing pain and inflammation, strengthening the immune system, and stimulating a parasympathetic nervous system response. There is a further need in the art for devices that mimic the feel and versatility of a human practitioner. Summary of the Invention

[0020] The disclosed subject matter describes a device that transmits a reciprocating motion to an individual. The reciprocating motion can, in some cases, produce a physiological response in the individual. The reciprocating motion of a skilled human practitioner generally produces superior physiological results. One goal of a reciprocating medical device is to accurately replicate the motion of a skilled human practitioner to achieve optimal physiological results. Another goal of a reciprocating medical device is to achieve a precise reciprocating motion that exceeds the capabilities of a skilled human practitioner. The reciprocating medical device may make subtle adjustments to the amplitude, frequency, and vector of the reciprocating motion based on feedback sensed by the reciprocating medical device.

[0021] Various factors that may explain how one patient moves differently from another include the individual's mass, the amplitude of vibration, and the frequency of vibration. The reciprocating medical device may adjust its movement based on these factors. The reciprocating device may be portable so that it can be positioned at the foot of a bed while the individual lies in bed with the individual's heel resting within a foot holder attached to the reciprocating medical device by a compliant rod.

[0022] The reciprocating medical device may vibrate the holder to deliver gentle compressive vibrations to the individual. With each compressive vibration, the holder is pushed out, gently pushing the individual in a direction from the feet toward the center of gravity or head so that the individual's head moves approximately 0-2.5 cm. In some alternative embodiments, the range of motion may be greater than 2.5 cm. For example, the range of motion may be 0-3.0 cm or 0-3.5 cm. The reciprocating medical device may be configured to adjust the range based on the individual patient and their condition. For example, for a patient in a vulnerable state, such as immediately after surgery, the reciprocating medical device may be set to a low frequency and low range of motion.

[0023] Clinical evidence has shown that the use of reciprocating medical devices has a significant impact on inflammation and alters the way blood clotting factors work. The placement of the reciprocating medical device and adjustment of the frequency and amplitude of the movements may depend on the location of the wound or surgery relative to the mucosal tissue. In various cases, blood vessels may be closer to the surface and may need to be treated differently to prevent bleeding.

[0024] After the holder is pushed out, it is retracted and the individual returns to their original position. In some alternative embodiments, the holder may be configured to only push the individual. In one exemplary embodiment, the holder is configured to both push and pull the individual. In one exemplary embodiment, the holder is configured to only pull the individual. When the individual is gently pushed to prevent slipping, a portion of the individual's skin maintains contact with the surface on which the individual is lying, allowing the individual to return to their original position. In this way, when the holder is retracted, the individual returns to their original position.

[0025] The frequency and amplitude of vibrations in the reciprocating medical device may be adjusted. In some alternative embodiments, the frequency and / or amplitude are automatically adjusted to match an individual's optimal frequency. In some cases, an individual's optimal frequency is the individual's frequency of movement that requires the least force to maintain. In other cases, best results may be achieved by deviating from the frequency that requires the least force to maintain. In one exemplary embodiment, the reciprocating medical device may sense the frequency that requires the least force to maintain and use this to establish a base frequency at which the body inherently moves for a given amplitude of movement. The reciprocating medical device may then deviate from the base frequency to provide optimal physiological results.

[0026] The reciprocating medical device may be configured to automatically adjust the frequency of vibration to an optimal frequency for an individual based on feedback from sensors embedded in the device that provide information about the individual's movement. The sensors may also provide information based on the individual's physiological response. For example, the sensors may measure heart rate or blood oxygen levels. The sensors may measure the amount of swelling in a body area.

[0027] Like the frequency, the amplitude of the vibrations may be adjusted to fit an individual's natural range of motion. The natural range of motion may be defined in a variety of ways. In one embodiment, the natural range of motion is the distance an individual can comfortably push without slipping. Like the frequency of the vibrations, the reciprocating medical device may automatically adjust the amplitude of the vibrations based on feedback. The feedback may be the force with which the individual pushes against the reciprocating medical device, such as the force of contact between the holder and the individual.

[0028] In some alternative embodiments, factors other than the inherent range of motion may be used to set the amplitude, frequency, and vector of the motion. Factors may include input from the operator of the reciprocating medical device regarding the patient's condition. Patient preference may also be a factor in setting the amplitude, frequency, and vector of the motion.

[0029] Factors that may affect the amplitude of the movement may include the mass of the individual, the friction of the surface on which the individual is standing, and the desired frequency of the movement. In one exemplary embodiment, the variable (V) is calculated using the formula (1): V=F α A β M γ " where V is determined to be the product of the individual's frequency (F), amplitude (A), and mass (M). The constant exponents α, β, and γ may be determined through experimentation. Once the intrinsic amplitude and frequency are determined, the amplitude and frequency may be adjusted based on exemplary Equation 1.

[0030] The holder for the reciprocating medical device may be shaped to allow a body part to rest comfortably within the holder while maintaining a large degree of freedom of movement. In one embodiment of the holder, the holder is shaped to allow an individual's heel to rest within the holder. The holder may include one or more compliant sections that allow the foot to move freely as reciprocating forces are transferred to the foot. In one exemplary embodiment, the foot is unconstrained within the holder, and the foot may rotate freely about the ankle while reciprocating motion is transferred to the individual. In some other embodiments, the compliant rod may flex to allow a limited degree of freedom of movement relative to the foot.

[0031] Referring to Figure 1, Figure 1 is a schematic diagram 100 of a reciprocating medical device 102 illustrating components that may be used in one embodiment of the disclosed subject matter. The reciprocating medical device 102 may be used to provide therapy to an individual 103 similar to that of a human practitioner massaging a patient. The human practitioner may adjust the frequency and range of motion of the massage based on feedback from sensors. Similarly, the human practitioner may move the position of the individual 103 to allow for freedom of movement.

[0032] Similar to a human practitioner, the reciprocating medical device 102 adapts to the individual 103 based on feedback from sensors. The reciprocating medical device 102 may adjust the frequency and amplitude of vibrations. The reciprocating medical device may provide some freedom of movement to the individual 103 by allowing the ankle of the individual 103 to rotate freely when the reciprocating medical device 102 holds the heel of the individual 103. Flexible compliant rods may also provide limited freedom of movement to the individual's foot.

[0033] The reciprocating medical device 102 includes a vibration mechanism 104 and a holder 120. The vibration mechanism 104 creates a reciprocating motion 124 that is transmitted to the individual 103. The vibration mechanism 104 may have control over the frequency and amplitude of the reciprocating motion 124. The vibration mechanism 104 may receive feedback such that the vibration mechanism 104 can adjust the frequency and / or amplitude of the reciprocating motion 124 based on the feedback.

[0034] The vibration mechanism 104 may include a controller 106 and an actuator 108. The controller 106 is a computer system capable of sending instructions that, when executed, control the reciprocating motion 124 of the vibration mechanism 104. The controller 106 may be a single computer system, an Internet of Things (IoT) device, a co-located computer, a cloud-based computer, etc. The controller 106 may include an amplitude control module 110 and a frequency control module 112.

[0035] The amplitude control module 110 determines the amplitude of the reciprocating motion 124 generated by the vibrating mechanism 104. The amplitude control module 110 may be configured to adjust the amplitude of the reciprocating motion 124 based on feedback from sensors. Various criteria may be used by the amplitude control module 110 to determine the amplitude. The amplitude of the reciprocating motion 124 can be divided into a peak and a valley. The peak is the furthest point at which the vibrating mechanism 104 can push the individual 103. The valley is opposite the peak and exists at the point at which the vibrating mechanism 104 retracts the furthest from the individual 103.

[0036] In some alternative embodiments, the amplitude control module 110 may set the peaks and valleys based on feedback from sensors embedded in the device that provide information about the movement of the individual 103 and / or the individual's physiological response. In one embodiment, the feedback is the force the individual 103 exerts on the reciprocating medical device 102. In some alternative embodiments, the feedback is a physiological measurement of the individual, such as a sensor measuring inflammation in the individual. In one exemplary embodiment, the amplitude control module 110 may be configured to set the peaks such that the force the individual 103 exerts on the reciprocating medical device 102 on the forward stroke remains below a maximum force. The amplitude control module 110 may be configured to set the valleys such that the force exerted by the individual 103 remains above a minimum force. In some alternative embodiments, the amplitude control module 110 may be configured to set the peaks and valleys based on measurements other than the force exerted by the individual. In one exemplary embodiment, after setting the peaks and valleys based on the force exerted by the individual 103, the amplitude control module 110 may further adjust the peaks and valleys based on sensors measuring a physiological response from the individual. Examples of sensors that measure physiological responses may be a thermometer or a respiration sensor.

[0037] The frequency control module 112 determines the frequency of the reciprocating motion 124 of the vibrating mechanism 104. The frequency control module 112 may be configured to set the frequency of vibration based on feedback from sensors. Various forms of feedback may be used by the frequency control module 112 to determine the frequency. In one embodiment, the frequency control module 112, similar to the amplitude control module 110, may determine the frequency based on the force with which the individual 103 presses against the reciprocating medical device 102. The frequency control module 112 may set the frequency so that a minimum force is exerted by the individual 103 over a period of the vibrating mechanism 104. In some alternative embodiments, the frequency control module 112 may determine a frequency other than the frequency of minimum force or resistance. In one example, the frequency control module may determine the frequency of minimum force or resistance and then modify the frequency based on a physiological response from the individual. For example, the frequency control module 112 may receive physiological measurements from the individual. Examples of physiological measurements may be the individual's heart rate, respiratory rate, and blood oxygen level. In some alternative embodiments, the frequency control module 112 may receive a measurement correlated to inflammation in the individual. One example of a measurement correlated to inflammation may be a color sensor transmitting the color of an inflamed area of ​​skin. The frequency control module 112 adjusts the frequency to maximize a beneficial physiological response or minimize an adverse physiological response. For example, the frequency may be adjusted to reduce inflammation in the individual 103.

[0038] The actuator 108 causes the vibration mechanism 104 to perform a reciprocating motion 124. The actuator 108 may include a motor 114 and a feedback sensor 116. The motor 114 may be any machine that converts any form of energy into mechanical energy. In some alternative embodiments, the motor 114 is a servo motor that precisely controls the position of the output generated by the motor 114. The actuator 108 may be connected to the holder 120 via an actuator rod 118. The actuator 108 moves the holder 120 in a reciprocating motion 124 based on an amplitude and frequency set by the controller 106.

[0039] The feedback sensor 116 senses a feedback force based on the interaction between the holder 120 and the individual 103. The data measured by the feedback sensor 116 may be transmitted to the controller 106 to determine an optimal amplitude and frequency of the reciprocating motion 124. The feedback sensor 116 may collect various forms of data based on the interaction between the holder 120 and the individual 103.

[0040] In one embodiment, the feedback sensor 116 may measure the force exerted by the holder 120 on the individual 103. In some other embodiments, the feedback sensor 116 may measure the force exerted by the holder on the individual 103 with a force meter. The force measured by the force meter may be used by the amplitude control module 110 and the frequency control module 112. In one example, the amplitude control module 110 sets a trough at the position of the actuator 108 where the feedback sensor measures the minimum force. Similarly, the amplitude control module 110 may set a peak at the position of the actuator 108 where the feedback sensor measures the maximum force. The minimum and maximum forces may be determined manually or automatically. In some other embodiments, the feedback sensor may be a current sensor that measures the current, i.e., the torque exerted by the motor 114. The torque exerted by the motor 114 is directly proportional to the force exerted by the holder 120 on the individual 103.

[0041] The holder 120 is the portion of the reciprocating medical device 102 that contacts the individual 103. The reciprocating motion 124 generated by the actuator 108 is transferred to the holder 120 via the actuator rod 118, and the holder 120 transfers the reciprocating motion 124 to the individual 103. In some alternative embodiments, the feedback sensor 116 may be embedded in the holder 120. In some alternative embodiments, the feedback sensor 116 may be embedded in the actuator 108 or the actuator rod 118. In one embodiment, the holder 120 may be formed such that the holder 120 may transfer the reciprocating motion 124 by pushing, rather than pulling, the individual 103. In one exemplary embodiment, the holder 120 may be configured to push and pull the individual 103.

[0042] In one embodiment, the holder 120 is configured to hold one or two feet of the individual 103. The shape of the holder 120 may allow one or two feet of the individual 103 to remain in the holder 120 while freely rotating about the ankle. This freedom of movement may allow the individual 103 to be comfortable and thereby derive the most benefit from the reciprocating motion 124. If the individual 103 moves position as the holder 120 allows, the controller 106 of the vibration mechanism 104 may adjust the frequency and amplitude based on the individual's 103's new position. The reciprocating medical device 102 may further be configured to allow the individual's feet to freely rotate and move as the vibration motion is transmitted to the feet.

[0043] In some alternative embodiments, the reciprocating medical device 102 may require a brace 122 placed against the individual 103 to stabilize the reciprocating medical device 102 as the reciprocating motion 124 is transferred to the individual 103. In some alternative embodiments, the reciprocating medical device 102 may be lightweight and portable, so there is a need for a brace 122 to immobilize the reciprocating medical device 102 during operation. The brace 122 may be any object that is strong and / or heavy enough to remain immobilized when the actuator 108 presses against the individual 103.

[0044] In some alternative embodiments, the reciprocating medical device 102 may include a medical sensor 130. The medical sensor 130 may be configured to detect various physiological measurements in the individual 103. Examples of medical sensors include, but are not limited to, a heart rate sensor, a respiration sensor, a blood oxygen level sensor, a thermometer, and a sweat sensor. In an exemplary embodiment, the medical sensor 130 may measure indicators of inflammation. For example, the medical sensor 130 may include a camera configured to measure inflammation in an area of ​​the individual 103. The camera may measure inflammation by recognizing indicators of inflammation, such as swelling or color changes. In one example, the controller 106 may process the camera images with a machine-learned algorithm to recognize inflammation, or the camera may include a controller that processes the images. The machine-learned algorithm may be trained by various machine-learning algorithms, such as neural networks. The machine-learning algorithm may use training images of inflamed body parts to train the machine-learned algorithm to recognize inflammation in the individual 103.

[0045] Referring to Figure 2, Figure 2 is a schematic diagram of a vibration mechanism 200 of the reciprocating medical device 102. The vibration mechanism 200 may be a variety of mechanisms capable of transmitting motion to the individual 103. The motor 114 of the vibration mechanism 200 may be of various types, including electric, gas, pneumatic, and hydraulic. In one embodiment shown in Figure 2, the vibration mechanism 200 converts rotational motion into linear motion.

[0046] The motor 114 rotates the rotor 202. The rotor 202 may be of various sizes. In one embodiment, in which the rotor 202 is configured to rotate a full circle to cause the reciprocating motion 124, the radius of the rotor 202 may determine the amplitude of the reciprocating motion 124. As the rotor 202 is rotated by the motor 114, a revolute joint 204 may couple the rotor 202 to an actuator rod 208. The actuator rod 208 may be guided by a slide 210 that secures one end of the actuator rod 208 so that it moves in a linear path. The radius at which the revolute joint 204 rotates relative to the rotor 202 may determine the amplitude of the reciprocating motion 124 when the rotor 202 rotates a full circle. In some other embodiments, the motor 114 is a servo motor with fine control over the rotational position of the rotor 202. The servo motor may be configured to oscillate back and forth in less than a full circle to cause the reciprocating motion 124. The amplitude of the servo motor may be based on the start and end positions of the rotor 202 as the motor 114 oscillates between the start and end positions.

[0047] The vibration mechanism 200 may have a radius adjuster 206 that can modify the radius of the revolute joint 204. In some alternative embodiments, the rotor 202 is rotated a full circle in one direction to cause the reciprocating motion 124. The radius adjuster 206 may adjust the amplitude of the vibration by changing the radius of the revolute joint 204. The frequency may be adjusted by modifying the rotational speed of the rotor 202. In some alternative embodiments, the reciprocating motion 124 is caused by a precise reciprocating motion of a servo rotor. The frequency is determined by the speed at which the reciprocating motion is caused by the servo motor.

[0048] Referring to FIG. 3, FIG. 3 is an illustration of a holder 300 for a reciprocating medical device 102. The holder 300 may be configured to hold or support various parts of the body. The holder 300 shown in FIG. 3 is configured to support the heel of the foot. In some alternative embodiments, the holder 300 may be configured to support other parts of the body, such as the hand, head, or shoulder. Multiple holders 300 may be used together in one reciprocating medical device 102. The diagram shown in FIG. 9 illustrates two holders 300 being used in one reciprocating medical device 102.

[0049] In the embodiment shown in Fig. 3, the holder 300 is configured so that the heel of the foot can rest on a quarter-pipe shaped heel rest 310. A pair of protuberances 320 are erected on the heel rest 310. The pair of protuberances 320 and the heel rest 310 provide support for the heel of the foot while allowing the foot to rotate around the ankle. The pair of protuberances 320 are aligned on the sides of the holder 300 that face the foot when the heel is resting on the heel rest 310. The pair of protuberances 320 do not completely encase the sides of the foot, allowing the foot to move freely laterally.

[0050] The heel rest 310 provides support for the heel of the foot against gravity when the heel rests within the holder. The curved heel stop 340 portion of the holder 300 is curved to provide support against gravity and to transfer the reciprocating motion 124 from the reciprocating medical device 102. The reciprocating medical device 102 transfers the reciprocating motion 124 of the foot toward the center of gravity of the individual 103. The lower portion of the curved heel stop 340 supports the heel against gravity, while the upper portion of the curved heel stop 340 transfers the reciprocating motion 124 to the foot. Above the curved heel stop 340 is the midfoot support 330.

[0051] The midfoot support 330 transfers the force of the reciprocating motion 124 from the reciprocating medical device 102 to the foot. The quarter pipe and pair of ridges 320 provide a depression for the foot to rest on the holder 300 while allowing the foot to move freely. The pair of ridges 320 line the side of the holder 300 from the heel rest 310 to the curved heel stop of the midfoot support 330. The shape of the quarter pipe of the holder 300 can be a heel rest, a curved heel stop, a midfoot support, or any combination thereof, or the entire side of the holder 300 facing the foot, as shown in FIG. 3 .

[0052] The holder 300 may be configured to support a body part other than the foot. In one embodiment, the holder 300 may be configured to accommodate the reciprocating motion 124 on the back of the individual 103. A holder 300 that supports the back may be configured so that the individual 103 can sit against the holder 300 while the holder 300 transmits the reciprocating motion 124 in a direction from the back to the chest. In an exemplary embodiment, the holder 300 may be configured to support the hand. Similar to the shape of the holder 300 shown in FIG. 3 , in which the holder 300 transmits the reciprocating motion 124 through the heel of the foot, the holder 300 may transmit the reciprocating motion 124 through the palm of the hand.

[0053] Referring to Figure 4, Figure 4 is an illustration 400 of interstitial fluid 402 between cells 404 in the tissue of an individual. Interstitial fluid 402 is the fluid that resides between cells 404. Interstitial fluid 402 originates from fluid pumped through the bloodstream and passing through capillary walls 408 of capillaries 406.

[0054] Interstitial fluid 402 delivers nutrients to cells 404 and removes waste products. Through the flow of interstitial fluid 402, the body performs self-cleaning functions. Additionally, immune cells such as macrophages, B lymphocytes, and dendritic cells travel through the interstitial fluid 402 to detect foreign proteins, bacteria, and viruses. An inflammatory response changes the permeability of capillary walls 408, allowing more fluid to seep through the capillary walls and into tissues. This includes excess fluid resulting from an inflammatory response such as trauma, infection, or an allergic reaction.

[0055] Inflammation is a condition in which there is an excess of interstitial fluid 402 within tissue. Therefore, movement of interstitial fluid 402 contributes to inflammation. Whether caused by trauma or infection, damaged tissue releases proteins as a signal to the rest of the body, initiating an inflammatory response. The inflammatory response is limited by the vagus nerve, which responds to oscillatory motion. In particular, stimulation of the vagus nerve has been shown to suppress inflammation. Therefore, oscillatory motion transmitted to the body by the reciprocating medical device 102 may stimulate the vagus nerve, thereby reducing inflammation. The reciprocating medical device 102 may further adjust the oscillatory motion based on feedback from the medical sensor 130 to optimize the effect on the vagus nerve to control inflammation. The oscillatory motion may also be adjusted based on feedback from the medical sensor 130 to optimize stimulation of the parasympathetic response.

[0056] Referring to Figure 5, Figure 5 is an illustration 500 of the interconnectivity of interstitial fluid 502 with capillaries 516 and the lymphatic system. Blood is pumped through the circulatory system via arteries 512. As blood flows through capillaries 516, fluid leaves the capillaries 516. Here, the fluid moves between tissues and cells and is called interstitial fluid. The remaining blood is pumped through veins 514.

[0057] As mentioned above, interstitial fluid sustains cells 510 within tissues. The interstitial fluid 502 then drains into lymphatic capillaries 504 and lymphatic vessels 506, where it is called lymph. When interstitial fluid 502 is within tissues and between cells, it is not pumped into the lymphatic system by contractions of the heart or muscle walls of blood vessels. Instead, interstitial fluid may circulate in response to muscle contractions and body movement.

[0058] The reciprocating medical device 102 applies a vibrational force to the interstitial fluid 502, encouraging it to circulate more vigorously through the lymphatic system. By moving the interstitial fluid 502, the reciprocating medical device 102 may clear out proteins that initiate the inflammatory reflex and reduce the associated inflammation. Additionally, some proteins from damaged tissue create signals that communicate with nearby cells, triggering those cells to begin dividing, thereby initiating healing of the damaged tissue. These healing-initiating proteins may be circulated more quickly in response to the vibrational motion. Clinical studies using the reciprocating medical device 102 have shown that moving patients at specific combinations of frequency and amplitude accelerates healing.

[0059] Referring to FIG. 6, FIG. 6 is an illustration 600 of the lymphatic system in an individual. Interstitial fluid is called lymph because it flows through the lymphatic system. Lymph may contain immune cells, apoptotic cells, proteins, infectious organisms, and antigens. Pressure gradients control the movement of lymph through lymphatic vessels 602 and 604. Additionally, muscle contractions and body movements can promote lymph flow. Various valves in the lymphatic system prevent backflow of lymph and promote forward flow of lymph relative to the blood circulation.

[0060] Studies in rats and dogs have shown that lymphatic pumping increases lymph flow. Lymphatic pumping may involve manual compression of specific body parts. For example, lymphatic pumping may involve compressing a body part 20 to 30 times for 2 to 5 minutes. Lymphatic pumping therapy in humans has been shown to have positive results in fighting infections.

[0061] The reciprocating medical device 102 may also promote lymphatic flow in the lymphatic system. Similar to a lymphatic pump, the oscillatory motion of the reciprocating medical device 102 may promote lymphatic movement through the lymphatic system, aiding healing and potentially helping to fight infection. Furthermore, by adjusting to a preferred frequency and amplitude, the reciprocating medical device 102 automatically optimizes the oscillatory motion to promote best results.

[0062] Referring to FIG. 7A, FIG. 7A is a flow diagram 700 of a process for adjusting the reciprocating motion 124 to an optimal frequency for the individual 103. The optimal frequency for the individual 103 may be the frequency of back-and-forth motion that requires the least force to maintain. In some alternative embodiments, the optimal frequency is based on a physiological response from the individual and deviates from the frequency that requires the least force to maintain. In step 705, the reciprocating medical device 102 may vibrate a pad in contact with a body part of the individual 103 using a vibration mechanism 104. The pad may be the holder 300 shown in FIG. 3. The vibration mechanism 104 may transmit the reciprocating motion 124 to the remainder of the individual 103 via the pad and the body part. The reciprocating motion 124 may simulate movements induced by a human practitioner, such as a massage therapist. Just as a human practitioner adjusts a treatment for the individual 103, the reciprocating medical device 102 adjusts the reciprocating motion 124 that vibrates the individual 103 based on the individual 103.

[0063] In step 710, the reciprocating medical device 102 may dynamically change the frequency of vibration via the vibration mechanism 104 based on feedback from the sensors. The vibration mechanism 104 may adjust the frequency to an optimal frequency for the back and forth motion of the individual 103. The optimal frequency for the back and forth motion may be found by measuring feedback from the sensors as the individual 103 is oscillated back and forth. The feedback sensor 116 may measure the force exerted by the holder 120 on the individual 103. Similarly, the medical sensor 130 may measure a physiological response in the individual. The frequency control module 112 may determine the optimal frequency based on measurements from the feedback sensor 116 and the one or more medical sensors 130.

[0064] In step 715, the reciprocating medical device 102 may dynamically vary the amplitude of vibrations by the vibrating mechanism 104 based on feedback from the sensors. Similar to the frequency of vibrations, the vibrating mechanism 104 may modify the amplitude of vibrations based on feedback from the sensors. The amplitude control module 110 may adjust the amplitude based on measurements from the feedback sensor 116 and one or more medical sensors 130.

[0065] 7B, which is a flow diagram 750 of a process for adjusting the reciprocating motion 124 to an optimal frequency for the individual 103. In step 755, the reciprocating medical device 102 may vibrate one or more body parts on the individual 103. In one embodiment, the reciprocating medical device 102 may vibrate two feet of the individual 103. When the legs of the individual 103 are extended, the entire body is exercised, so the vibrations may be transmitted through the feet and immobilized knees to the hips and ultimately to the head. In some alternative embodiments, the reciprocating medical device 102 may vibrate body parts of the individual 103 other than the feet.

[0066] In step 760, the reciprocating medical device 102 may adjust the amplitude of the vibration to maintain a range of pressure on one or more body parts. The pressure on one or more body parts may be measured by a feedback sensor 116, which may be a force meter or the like. In one embodiment, the amplitude control module 110 of the vibration mechanism 104 may adjust the peak and valley of the amplitude separately. The peak is the point of vibration that is furthest toward the individual 103. The valley is the point of vibration that is furthest from the individual 103. In some other embodiments, the peak and valley are both modified by a single mechanism.

[0067] Because the peak is the farthest point toward the individual 103, it is likely to be the point of highest pressure, as measured by the feedback sensor 116 when the individual 103 is not vibrating. However, because various frequencies of vibration may produce different results, the peak may not always have the highest pressure among all points of vibration. The peak may be set in several different ways. In one embodiment, the peak is set at the point where the feedback sensor measures the maximum pressure. Similarly, the valley is considered to be the point of lowest pressure, as measured by the feedback sensor 116 when the individual 103 is not vibrating. The valley may be set at the point where the feedback sensor 116 measures the minimum pressure. The maximum and minimum pressures may be set in several different ways. In one embodiment, the maximum pressure is set as the average pressure exerted when the individual 103 is pushed 1 cm without vibration. The minimum pressure may be set as half of the maximum pressure.

[0068] In step 765, the reciprocating medical device 102 may adjust the frequency of oscillation to minimize changes in pressure exerted on one or more body parts. Like the amplitude, the frequency of oscillation may be adjusted based on measurements from the feedback sensor 116. The feedback sensor 116 may measure pressure in various ways, such as spring displacement. The oscillation frequency may be adjusted based on various criteria to find the optimal oscillation frequency for the individual 103. In one embodiment, the frequency may be adjusted to a frequency that results in the smallest change in pressure over a single oscillation, as measured by the deviation in pressure measurements by the feedback sensor. In an exemplary embodiment, the oscillation frequency is adjusted to a frequency that results in the lowest overall pressure over a single oscillation. In some alternative embodiments, the reciprocating medical device 102 may determine the individual's inherent oscillation frequency and amplitude and then further adjust the frequency and amplitude based on measurements from one or more medical sensors 130.

[0069] Referring to FIG. 8 , FIG. 8 is an illustration 800 of a foot 802 of an individual 103 resting within a holder 805 of a reciprocating medical device 102. The holder 805 may be configured to hold a variety of body parts. The holder 805 shown in FIG. 8 is configured to hold the hindfoot and midfoot of a foot 802. The bottom surface of the midfoot contacts a midfoot support 810. The midfoot support 810 presses against the bottom surface of the foot 802, thereby transmitting a reciprocating motion 870 to the foot 802. A heel rest 820 supports the weight of the foot 802 when the heel of the foot 802 is pointing toward the ground.

[0070] In some alternative embodiments, the individual 103 lies down and rests their heels on a pair of holders 805. Each holder 805 only partially covers the side of the foot 802, allowing the foot 802 to freely rotate side to side by rotating around the ankle. As the individual 103 lies down with one or both feet on the holders 805, the holders 805 may oscillate in a back-and-forth reciprocating motion 870. The reciprocating motion 870 may be divided into a pushing motion and a pulling motion. The holders 805 transmit the pushing motion force 830 through the soles of the feet. The pushing motion may cause the body to be pushed in the direction from the feet to the head. The skin of the individual 103 in contact with the horizontal surface may resist the movement as the rest of the body moves. In some alternative embodiments, the pulling motion does not transmit any force to the foot 802. However, the body's force 860 may keep the foot 802 in contact with the holder 805 during the pulling motion. When the holder 805 is pulled away from the body during a pulling movement, the body may follow the holder 805 even though the holder 805 does not transmit a pulling force to the foot 802 .

[0071] Gravitational force 850 may balance the pushing force 840 from heel rest 820. Gravitational force 850 may push the rest of the body of individual 103 to create bodily friction against the horizontal surface on which the body of individual 103 is lying. The friction may prevent individual 103 from slipping as a result of pushing force 830. As a result of the friction preventing the body from slipping, bodily force 860 resists the pushing motion and propels the body toward holder 805 during the pulling motion.

[0072] Because every body is different, the force and distance a body can be propelled toward the holder 805 during a pulling motion may vary. Similarly, some bodies may resist movement more than others during a pushing motion. Because of this, the ideal frequency and amplitude of the reciprocating motion 870 may be different for every individual 103. The reciprocating medical device 102 may determine the ideal frequency and amplitude by measuring the force 830 of contact between the foot 802 and the holder 805 and adjusting the frequency and amplitude based on the force of contact.

[0073] Referring to FIG. 9 , FIG. 9 is an illustration of an embodiment of a holder 900 for a reciprocating medical device that holds two feet 902. In some alternative embodiments, the holder 900 may hold the body part by allowing the body part to rest within the holder 900. In one exemplary embodiment, the holder 900 may be a pad that presses against the body part. In the embodiment shown in FIG. 9 , the holder 900 is configured to allow two feet to rest by placing the heels of the feet on the heel rests 310 of the holder 900. In some alternative embodiments, the holder 900 may be configured to support the back of the individual 103 as the individual 103 sits against the holder 900.

[0074] The holder 900 may be attached to an actuator rod 118 that transfers the reciprocating motion 124 to the holder 900. As shown in FIG. 9 , a platform 908, which is transparent in FIG. 9 to provide a more complete view of the holder 900, provides a connection point for the foot holder 904. The actuator rod 118 may also be connected to the platform 908. The actuator rod 118 is part of the actuator 108 that provides the pushing and pulling forces for the reciprocating motion 124.

[0075] When the vibration mechanism 104 transmits the reciprocating motion 124 to the holder 900 through the actuator rod 118, the holder 900 may reciprocate with the actuator rod 118. The platform 908 allows the motion of the actuator rod 208 to be transmitted to an object coupled to the platform 908. As shown in FIG. 9 , the platform 908 is coupled to two foot holders 204. The foot holders 904 are coupled to the platform 908 by compliant rods 906. The compliant rods 906 may be configured to couple the foot holders 904 at various angles, regardless of the angle of the platform 908. For example, the compliant rods 906 may couple the foot holders 904 to the platform 908 so that the foot 902, resting on the foot holder 904, can point its toes in a direction that is comfortable for the individual 103. The compliant rods 906 may be flexible, allowing limited movement that deviates from the movement of the actuator rods. In some alternative embodiments, the compliant rod 906 only allows deflection perpendicular to the actuator rod's motion. Deviations as the actuator vibrates can result in the foot holder 904 moving in an elliptical motion rather than a linear motion.

[0076] In an exemplary embodiment, the compliant rods 906 may be made of a material that allows the compliant rods 906 to flex only linearly. For example, the compliant rods 906 may flex only along an axis that runs along the length of the compliant rods 906. Furthermore, the flexibility of the compliant rods 906 may vary between individual compliant rods 906. Thus, the tolerance of the compliant rods 906 may be constrained based on the geometry and flexibility of the individual compliant rods 906.

[0077] 9, the foot holder 904 allows the foot of the individual 103 to move freely from side to side and to be pulled away from the foot holder 904. The foot holder 904 may partially wrap around the side of the foot 902 to provide stability to the individual 103. However, even though the side of the foot holder 904 partially wraps around the side of the foot 902, the foot 902 of the individual 103 may still move freely from side to side.

[0078] The foot holder 904 is configured to comfortably apply a reciprocating pushing force to the foot 902. The actuator rod 118 may push the platform 908 such that the pushing force is transmitted in a direction from the foot 902 to the head. The actuator rod 118 may also pull the platform such that the foot holder 904 is pulled away from the foot 902. However, the foot 902 is not pulled by the foot holder 904. Instead, the foot 902 may follow the foot holder 904 as it is pulled away from the foot 902 due to the tendency of the individual's 103 body to remain in one place when the individual 103 lies on a horizontal surface.

[0079] Holder 900 may be configured to hold various body parts other than feet 902. For example, holder 900 may be configured to provide a reciprocating motion 124 to the back of the buttocks of individual 103 when individual 103 is in a seated position. In an embodiment, holder 900 may be a flat pad that provides a comfortable pushing motion to the buttocks of individual 103. Just as feet 902 of individual 103 follow foot holder 904 when foot holder 904 is pulled away from the buttocks, buttocks of individual 103 may follow holder 900 when holder 900 is pulled away from the buttocks.

[0080] Referring to FIG. 10 , FIG. 10 is an illustration 1000 of a reciprocating medical device 102 capable of transmitting a reciprocating motion 124 to an individual 1002. The reciprocating medical device 102 may have a vibration mechanism 1004 that vibrates to produce a reciprocating motion 1012 in the individual 1002. The vibration mechanism 1004 may convert the oscillating rotation into linear vibration. The vibration mechanism may be coupled to an actuator rod 1006 that transmits the vibration in a linear direction 1010. As shown in FIG. 10 , the actuator rod 1006 transmits the vibration in a direction 1010 from the feet to the head of the individual 1002 when the individual 1002 is lying on a horizontal surface 1014.

[0081] The actuator rod 1006 transmits the reciprocating motion 1012 to the holder 1008. The holder 1008 may support various parts of the body. As shown in FIG. 10 , the holder 1008 supports the feet of the individual 1002. As the holder 1008 pushes the individual 1002 in a direction 1010 from the feet of the individual 1002 toward the head of the individual 1002, a force from the reciprocating medical device 102 is transmitted to the feet of the individual 1002. As shown in FIG. 10 , if the knee of the individual 1002 is fixed, the pushing force from the holder 1008 may propagate through the body of the individual 1002 to push the head of the individual 1002 in the direction 1010 from the feet to the head.

[0082] The feedback sensor 116 may be present in various portions of the reciprocating medical device 102. The feedback sensor 116 may be a force meter within the holder 1008, such that the feedback sensor 116 can measure the force of contact between the foot and the holder 1008. Alternatively, the feedback sensor 116 may be within the vibration mechanism 704, such that the feedback sensor can measure the force with which the actuator rod 1006 pushes against the holder 1008. In some alternative embodiments, one or more medical sensors 130 provide physiological measurements of the individual 1002 to the reciprocating medical device 102.

[0083] The controller 106 may adjust the amplitude and frequency of the vibration mechanism 1004 based on measurements from the feedback sensor 116 and / or the medical sensor 130. In some alternative embodiments, the vibration mechanism 1004 causes the reciprocating motion 1012 by repeatedly rotating the rotor 202 in one direction. In one exemplary embodiment, the vibration mechanism 1004 causes the reciprocating motion 1012 by repeatedly reversing the rotation of the rotor 202, causing the rotor 202 to rotate back and forth. The controller 106 may adjust the frequency to minimize the force measured by the feedback sensor 116 over the course of one vibration. The controller 106 may adjust the amplitude to keep the force measured by the feedback sensor 116 within a minimum and maximum range over the course of one vibration. Different criteria, such as physiological measurements from one or more medical sensors 130, may be used by the controller 106 to adjust the frequency and amplitude of the reciprocating motion 1012.

[0084] The horizontal surface 1014 can be a variety of objects or materials. Ideally, the horizontal surface 1014 is comfortable for the individual 1002 to lie on as the reciprocating motion 1012 is transferred to the individual 1002. The horizontal surface can affect the optimal frequency of the individual 1002 because it provides friction that allows the individual 1002 to return to its original position after the reciprocating medical device 120 pushes against the individual 1002.

[0085] 11, which is a block diagram of a computer system 1100 that may be implemented in various embodiments of the controller 106 for the reciprocating medical device 102. The controller 106 determines the amplitude and frequency of the vibration mechanism 1110 based on measurements from a feedback sensor 1112. The controller 106 may be a single computer system 1100, a collocated computer system 1100, a cloud-based computer system 1100, or the like.

[0086] The computer system 1100 may include a bus 1102. The bus 1102 connects the various components of the computer system 1100 so that the various components can communicate with each other. The computer system 1100 may include a processor 1104 connected to the bus 1102. The processor 1104 performs calculations and executes instructions communicated to the processor 1104. The processor 1104 may be an integrated circuit such as a central processing unit ("CPU"). Instructions are communicated to the processor 1104 by memory 1106 through the bus 1102. After the processor 1104 executes the instructions, the executed instructions are passed back to the memory 1106. In this manner, the memory 1106 handles all data passed to and from the processor 1104. Types of memory 1106 include random access memory ("RAM"), read-only memory ("ROM"), etc.

[0087] The memory 1106 may send instructions that, when executed, cause the vibrating mechanism 1110 to operate. The instructions that the memory 1106 sends to the vibrating mechanism 1110 may be processed by the processor 1104. The vibrating mechanism 1110 may start, stop, change the frequency, and change the amplitude of the reciprocating motion 124 generated by the vibrating mechanism 1110. The memory 1106 may also receive measurements from a feedback sensor 1112. The memory 1106 may send the measurements from the feedback sensor 1112 to the processor 1104. The processor 1104 may process the measurements and generate instructions that are sent back to the memory 1106. The memory 1106 may send the processed instructions to the vibrating mechanism 1110 to modify the operation of the vibrating mechanism 1110 or to keep the operation of the vibrating mechanism 1110 unchanged. The memory 1106 and the processor 1104 may execute a program that determines an optimal frequency for the individual 103 based on measurements from the feedback sensor 1112. Similarly, the memory 1106 and processor 1104 may execute a program that determines an ideal amplitude for the individual 103. The computer system 1100 may be configured to allow the individual 103 to manually set the frequency and amplitude. Alternatively, the individual 103 may limit the frequency and amplitude at which the vibration mechanism 1110 may operate.
