Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of U.S. Provisional Patent Application No. 63 / 044,625, filed on June 26, 2020, and U.S. Provisional Patent Application No. 63 / 123,301, filed on December 9, 2020, the entire contents of each of which are incorporated herein by reference. Technical Field

[0003] The present disclosure generally relates to systems, devices, and methods for mounting a goniometer proximate to a user's knee joint. Background Art

[0004] Patients often require physical therapy to recover from surgery or injuries such as knee replacement surgery. Physical therapy can include exercises to increase a patient's strength and flexibility. If a patient overextends a muscle or joint, further injury to the muscle or joint, surrounding tissue, or repaired tissue can occur. If a patient does not exercise the muscle or joint to achieve a proper range of motion, the joint may become stiff and require additional surgery. Measuring and monitoring range of motion during physical therapy can help prevent further injury to the patient and lead to a faster recovery time.

[0005] A goniometer is an instrument that can be used to measure the range of motion or joint angle of a patient's body. A standard goniometer consists of a fixed arm that cannot move independently, a movable arm attached to a pivot in the center of the body, and a protractor body with an angle of 0 to 180 or 360 degrees. The fixed arm is attached to one limb or part of the patient's body (e.g., the thigh), and the movable arm is attached to another limb or part of the patient's body (e.g., the calf). The pivot can be a rivet or screw-like device located in the center of the body that allows the movable arm to move freely on the body of the device so that the clinician can obtain a measurement of the angle of motion of the patient's joint (e.g., the knee joint). The measurement can be used to track the progress of the rehabilitation program. Each time the patient undergoes rehabilitation treatment, the clinician will place or attach the goniometer device to the patient using, for example, a strap. The patient may have the goniometer device set up and joint motion measured by different clinicians. Depending on the clinician's experience, the goniometer may be attached to different positions on the patient, which may affect the measurement accuracy. Due to equipment problems, the accuracy of repeated measurements may also be affected. Furthermore, if the goniometer is never attached to a patient, or if the goniometer is disassembled and needs to be reattached, incorrect placement of the goniometer and any supporting equipment may result in incorrect readings, thereby reducing the goniometer's utility.

[0006] Patients often require additional support for their knee joints. A knee brace is often used to provide this support. In some cases, a knee brace may include a device that limits the range of motion of the knee joint. Therefore, improvements to such devices and methods continue to be of interest. Summary of the Invention

[0007] Embodiments of systems, devices, and methods for mounting a goniometer proximate to a user's knee joint are disclosed. For example, a method of installing a device on a user includes: positioning the lateral epicondyle at the user's knee joint and marking the same position to define a knee joint indicator; installing a knee pivot anchor on the knee joint indicator; positioning the greater trochanter at the user's hip joint and marking the same position to define a hip joint indicator; positioning the lateral calf bone at the user's ankle joint and marking the same position to define an ankle joint indicator; installing the proximal end of the template to the knee pivot anchor, pivoting the template about the knee pivot anchor, and aligning the distal end of the template with the hip joint point; placing a first slot piece in a hole in the template and securing the first slot piece to the user in a proximal position with the distal end of the template aligned with the hip joint point; pivoting the template about the knee pivot anchor and aligning the distal end of the template with the ankle joint point; placing a second slot piece in the hole in the template and securing the second slot piece to the user in a distal position with the distal end of the template aligned with the ankle joint point; and removing the template and the knee pivot anchor from the user.

[0008] In other embodiments, a kit for mounting a device on a user comprises: an indicator assembly including a marker configured to place a mark on a user, and a set of adhesive pads configured to be placed on the user; a knee pivot anchor configured to be attached to the user; a template having a proximal portion configured to be pivotally mounted to the knee pivot anchor, a distal portion configured to be positioned at different positions on the user, and a hole; a set of slots configured to be interchangeably positioned in the holes of the template, and each slot is configured to be secured to the user at a respective position; and the template and knee pivot anchor are configured to be removed from the user while the slots remain on the user.

[0046] Symbols and nouns

[0047] Various terms are used to refer to specific system components. Different companies may refer to components by different names—this document does not intend to distinguish between components that differ in name but function. In the following discussion and in the claims, the terms "including" and "comprising" are used in an open-ended manner and, thus, should be interpreted to mean "including, but not limited to..." Similarly, the terms "coupled" or "coupled to" are intended to mean either an indirect connection or a direct connection. Thus, if a first device couples to a second device, that connection may be through a direct connection or an indirect connection via other devices and connections.

[0048] The terminology used herein is for the purpose of describing specific example embodiments only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The method steps, processes, and operations described herein should not be construed as necessarily being performed in the particular order discussed or illustrated, unless expressly identified as an order of execution. It should also be understood that additional or alternative steps may be employed.

[0049] The terms "first," "second," "third," etc., herein may be used to describe various elements, components, regions, layers, and / or sections; however, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, when terms such as "first," "second," and other numerical terms are used herein, no order or sequence is implied. Thus, without departing from the teachings of the example embodiments, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section. When the phrase "at least one" is used in conjunction with a list of items, it means that different combinations of one or more of the listed items may be used, and only one item from the list may be required. For example, "at least one of A, B, and C" includes any of the following combinations: A, B, C, A and B, A and C, B and C, and A, B, and C. In another example, when the phrase "one or more" is used with a list of items, it means that there may be one item or any suitable number of more than one item.

[0050] Spatially relative terms such as "inside," "outside," "below," "below," "lower," "above," "upper," "top," "bottom," etc. may be used herein. These spatially relative terms may be used to simplify descriptions to describe the relationship of one element or feature to another element or feature as shown in the figures. In addition to the orientations described in the accompanying drawings, spatially relative terms may also be meant to encompass different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being "below" or "beneath" other elements or features will be oriented as being "above" the other elements or features. Thus, the example term "below" may encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or other directions) and the spatially relative descriptions used herein may be interpreted accordingly. DETAILED DESCRIPTION

[0051] The following discusses various embodiments of the present disclosure. Although one or more of these embodiments are preferred, the disclosed embodiments should not be interpreted or otherwise used to limit the scope of the present disclosure, including the claims. In addition, it will be understood by those skilled in the art that the following description has broad application, and the discussion of any one of the embodiments is intended only as an example of that embodiment and is not intended to imply that the scope of the present disclosure, including the claims, is limited to that embodiment.

[0052] According to aspects of the present disclosure, Figure 1A and Figure 1BAn exemplary system or wearable device 100, such as a goniometer, for measuring and recording flexion and extension at a joint 107 of a user 102 is shown. The wearable device 100 includes first and second coupling devices or accessories 112, 114, 118, 120 (hereinafter referred to as a first accessory 118 and a second accessory 120) and can be configured to be removably coupled to the user 102 at opposing limbs 104, 106 of the joint 107. For example, Figure 1A and 1B As shown, the first accessory 118 and the second accessory 120 can be coupled to the user's leg at the user's 102 knee joint or at opposing limbs 104, 106 (e.g., thigh and calf) of the joint 107. As will be appreciated by those skilled in the art, the first accessory 118 and the second accessory 120 can be coupled to the user at opposing limbs of any other joint of the patient or user 102. It is further contemplated that the wearable device 100 can be used to measure flexion and extension of joints of an animal, a robot, or any other desired joint or joint equivalent.

[0053] To position the wearable device 100 relative to the joint 107, a person, such as a clinician, can identify the joint center 108, wherein the joint center 108 can be used to align the wearable device 100 with the joint 107. The clinician can use an alignment device to identify and mark the joint center 108. For example, the alignment device can be used to mark the skin of the user 102 at the joint center 108 using a marker, a pen, or any other desired tool. Further, the alignment device can be used to identify and mark the positions of the first attachment 118 and the second attachment 120 on the opposing limbs 104, 106 relative to the joint center.

[0054] Reference Figures 2A to 6 , the wearable device 100 includes an exemplary device or apparatus 110 such as a goniometer. Hereinafter, the device or apparatus 110 may be referred to as the goniometer 110. The goniometer 110 is configured to measure angular flexion and extension of a joint 107 of the user 102. The goniometer 110 has a top 122, a bottom 124, and opposing sides 126. The goniometer 110 may include a central hub 116 coaxially aligned with an axis A and first and second arms 128, 130, wherein the arms 128, 130 are coupled to the central hub 116 and are pivotable or rotatable about the axis A and the central hub 116. More specifically, the first and second inner ends 132, 134, respectively, of the arms 128, 130 are coupled to the central hub 116. The arms 128, 130 extend outwardly from the central hub 116 to respective first and second outer ends 168, 170. In alternative embodiments, the arms 128, 130 may be integrally formed with the central hub 116. Embodiments of the goniometer may utilize various rotational or pivotal motions, such as with a shaft, rack and pinion system, or the like.

[0055] Reference Figure 3A and 3B The goniometer 110 can have a length L extending from a first outer end 136 to a second outer end 138. The length L can vary depending on the relative positions of the first and second arms 128, 130. For example, the maximum length L of the goniometer 110 can be measured when the arms 128, 130 are opposite each other. However, when the arms 128, 130 are parallel and positioned directly above and below each other, respectively, the minimum length L of the goniometer 110 can be measured between the outer ends 136, 138 and opposing sides of the central hub 116. The width W of the goniometer can be measured as the diameter of the central hub 116. Furthermore, the height H of the goniometer 110 can be measured from the bottom of the second arm 130 to the top of the first arm 128 or to the top of the central hub 116, whichever is greater.

[0056] In an exemplary embodiment, the central hub 116 includes a first or upper hub 146 and a second or lower hub 148. The hubs 146, 148 are coaxially aligned with each other and with the axis A. In addition, the hubs 146, 148 can be configured to rotate 360 ​​degrees relative to each other about the axis A. Further, each of the hubs 146, 148 can have a linkage arm 143 for coupling between the hub 146, 148 and the corresponding arm 128, 130. For example, the first arm 128 can be coupled to the linkage arm 143 of the first hub 146, and the second arm 130 can be coupled to the linkage arm 143 of the second hub 148.

[0057] In operation, embodiments of the arms 128, 130 can rotate, pivot, bend, or extend relative to the central hub 116. This design allows for complex joint motions, sliding motions of the joint, and a wide range of shapes and sizes of the patient's joint 107. Additionally, the design maintains the position of the central hub relative to the joint center 108. Embodiments of the device allow for free motion in many planes, but not in the joint's rotational plane. This allows the device to be adapted for many different individuals while still allowing for accurate measurements.

[0058] More specifically, as in Figure 4 As best shown in FIG, the first arm 128 and the second arm 130 can each include an inner link 142 disposed adjacent the respective inner ends 132, 134, and an outer link 144 disposed between the inner link 142 and the outer ends 168, 170. Figures 5A to 5C, the inner link 142 can be coupled to the link arm 143 so as to be coupled between the respective arm 128, 130 and the hub 146, 148. The inner link 142 can be configured to facilitate pivoting, bending, or extension of the respective arm 128, 130 relative to the central hub 116. A pin 164 can be used to couple the inner link 142 and the link arm 143 of the respective arm 128, 130 to allow pivoting, bending, or extension of the respective arm 128, 130. The pin 164 can be disposed perpendicular to the length of the arm 128, 130.

[0059] The outer link 144 can be coupled to the inner link 142 and the respective outer ends 136, 138. Figure 6 , the outer link 144 can be configured to couple to the inner link 142 to facilitate rotation of the respective arms 128, 130 relative to the central hub 116. The screw 162 can be configured to couple the outer link 144 to the inner link 142 to facilitate rotation of the respective arms 128, 130 about the screw 162, all relative to the central hub 116. The screw 162 can be aligned parallel to the length of the respective arms 128, 130. It should be understood that the first arm 128 and the second arm 130 can rotate in one or more directions by + / - 18 degrees or any other desired amount. Further, and with reference to Figures 5A to 5C , the outer link 144 can be configured to couple to the respective outer ends 136, 138 to facilitate further pivoting, bending, or extension of the respective arms 128, 130 relative to the center hub 116. A pin 164 can be used to couple the outer link 144 and the respective outer ends 136, 138 to allow the respective arms 128, 130 to further pivot, bend, or extend relative to the center hub 116. The pin 164 can be disposed perpendicular to the length of the respective arms 128, 130.

[0060] The first and second outer ends 136, 138 can include first and second goniometer attachments 168, 170, which can be integral with or coupled to the respective outer ends 136, 138. It should be understood that the goniometer attachments 168, 170 can be coupled or integral with the arms 128, 130 in any desired location or configuration. The first and second goniometer attachments 168, 170 can be configured to removably couple with the attachment 118, 120. Furthermore, each goniometer attachment 168, 170 can include one or more bosses 200 and one or more magnets 158 located adjacent the bosses 200 to facilitate coupling and alignment of the goniometer attachments 168, 170 with the attachment 118, 120. The bosses 200 and magnets 158 further facilitate alignment of the goniometer 110 relative to the attachment 118, 120. The arms 128, 130 may also include one or more arm alignment holes 140 configured to align with the attachments 118, 120, or with alignment markings on the user 102. The arms 128, 130 may further have one or more wings 202 extending from the side 126 of the goniometer 110, such as from the first or second goniometer attachment 168, 170. The wings 202 may be formed by or coupled to the first or second goniometer attachment 168, 170. The wings 202 may be tabs or have any other desired shape. The wings 202 may be configured to help the user vertically move the goniometer arm 128, 130 relative to the attachment, thereby facilitating disconnection of the goniometer 110 from the attachment 118, 120 without disconnecting the attachment 118, 120 from the user 102.

[0061] 7-9 , the attachments 118 and 120 may include first and second layers 172 and 174 coupled together, and a slot 176. When coupled together, each layer 172 and 174 and the slot 176 may be concentric with one another. The first attachment 118 may be identical to the second attachment 120 and interchangeable. The first layer 172, the second layer 174, and the slot 176 may be generally elliptical or any other desired shape. The first layer 172 may be larger than the second layer 174, and the second layer 174 may be larger than the slot 176. Furthermore, the first layer 172 may be thinner than the second layer 174, and the slot 176 may be thicker than both the first and second layers 172 and 174.

[0062] First layer 172 may have a top 182 and a bottom 184 and may be formed from padding, coated paper, plastic, textile, latex, or any other desired material. For example, top 182 may be formed from padding, and bottom 184 may include an adhesive material 236, such as a medical-grade adhesive or other suitable material. Adhesive material 236 couples to the skin of user 102 to attach accessories 118, 120 to user 102. Furthermore, top 182 may also include an adhesive layer 194, which may have an area smaller than that of first layer 172. Furthermore, adhesive layer 194 may be smaller than or equal to the area of ​​second layer 174. Adhesive layer 194 may be oval-shaped and define one or more notches or gaps in the peripheral boundary. For example, first layer 172 may define a notch 180 in the peripheral boundary to facilitate alignment of first accessory 118 relative to a predetermined location or marking on user 102. The notch may be V-shaped or have any other desired shape. Further, the first layer 172 can define a pair of voids or alignment holes 178 that can assist in alignment of the first accessory 118 relative to predetermined locations or landmarks on the user 102 .

[0063] The second layer 174 can have a top 186 and a bottom 188 and can be formed from a foam material or any other desired material. The second layer 174 can be coupled to the adhesive layer 194 of the first layer 172. To prevent disconnection, the foam material of the second layer 174 can reduce forces between the goniometer 110 and the accessories 118, 120. The top 186 of the second layer 174 can also have an adhesive layer 195 on its upper surface 238, which can have an area smaller than that of the slot 176. The adhesive layer 195 can have an oval shape with one or more holes or one or more cutouts that align with the alignment holes 178 of the first layer 172. The adhesive layers 194, 195 can be formed from an adhesive material or any other desired coupling material, such as a hook- or loop-type material. The first layer 172 can have a length L1 and a width W1. The second layer 174 can have a length L2 and a width W2. The adhesive layer 195 can have a length L3 and a width W3.

[0064] like 10A to 10DAs shown, the container 176 has a top 190 and a bottom 192. The slot 176 may include one or more notches 196. For example, the notches 196 may be located at opposite ends of the slot 176. The notches 196 may be used to align the first coupling device 112, the slot 176, or any other desired feature of the wearable device 100. The slot 176 may include one or more magnets 160. The magnets 160 may be neodymium magnets or any other desired magnets. The slot 176 may have recesses for receiving the magnets 160. The magnets 160 may be circular or any other desired shape. The two magnets 160 in the slot 176 may be located at opposite ends of the slot 176. The slot 176 may be sized to be received by and removably coupled to the upper surface 238 of the second layer 174.

[0065] More specifically, the slot 176 has a bottom side, such as the bottom 192, that can be coupled to the upper surface 238 of the second layer 174. The bottom 192 can have one or more hooks or loops to couple to the upper surface 238. Optionally, the upper surface 238 and the bottom 192 can include an adhesive material to facilitate removable coupling between the upper surface 238 and the slot 176. The top 190 of the slot 176 can have one or more grooves 198. The grooves 198 can be oval or have any other desired shape. The grooves 198 can also have tapered edges to help the user 102 disconnect from the slot 176 by moving the arms 128, 130 vertically relative to the slot 176. The two grooves 198 in the slot 176 can be formed at opposite ends or sides of the slot 176.

[0066] 11-12 , the groove 198 is sized to accommodate the boss 200 to align the goniometer 110 relative to the accessories 118, 120. Furthermore, the groove 198 is sized to allow slight movement of the boss 200 to compensate for slight translational motion of the joints 128, 130 when the goniometer 110 is worn by the user 102. This motion can reduce stress between the accessories 118, 120 and the skin, clothing, support, or any other desired location on the user 102 and prevent them from becoming disconnected.

[0067] When the user 102 moves the first or second limb 104, 106, the first or second arm 128, 130 moves or rotates with the first and second hubs 146, 148. The goniometer 110 can measure the rotation of the joint 107 by measuring the angle between the first and second hubs 146, 148. To achieve this, refer to Figure 4 、 Figure 1315 , the central hub 116 defines an opening for receiving and containing a printed circuit board (PCB) 152, a sensor 216, a retaining ring 154 or other retaining device for the hubs 146 and 148, a magnet 156, or any other components of the goniometer 110 that cooperate with each other to measure relative angular motion between the arms 128 and 130. More specifically, the first and second hubs 146 and 148 can define an opening in the central hub 116.

[0068] To close the opening, a cover 150 can be attached to the central hub 116, and more specifically, to the first hub 146. The cover 150 can be removably coupled to the first hub 146 or any other desired location. The cover 150 can also be configured to inhibit movement of the PCB 152 and other components located within the central hub 116. For example, when the cover is closed, the bottom of the cover 150 can apply direct or indirect pressure to the PCB 152. The cover 150 can have a snap mechanism 226 configured to attach and detach the cover from the central hub 116, such as a finger snap or any other desired mechanism. The assembly can be waterproof or non-waterproof. For example, the cover 150 can enable or disable waterproofing of the assembly.

[0069] Magnet 156 may be coupled to second hub 148, and sensor 216, also disposed in center hub 116, may be configured to detect rotation of magnet 156. Sensor 216 may be configured to measure rotation of magnet 156 with a sensitivity of up to one hundredth of a degree or any other desired sensitivity.

[0070] like Figures 13 to 14C As shown, the central hub 116 includes a first hub 146 rotatably positioned above a second hub 148. An outward notch 208 can be coupled to the first hub 146 or any other desired location. The outward notch 208 can be formed with or attached to the first hub 146. The PCB 152 can be removably disposed in the central hub 116. The PCB 152 can have an inward notch 210. The outward notch 208 can be configured to couple with the inward notch 210 to align the sensor 216 and the magnet 156. This alignment can limit movement of the PCB 152 within the central hub 116.

[0071] When the cover 150 is removed, the PCB 152 can be accessed. Figure 14BA battery housing 206 is shown coupled to the PCB 152. The battery housing 206 can be attached to the top side 212 of the PCB 152. The battery housing 206 can be formed from a conductive metal or any other desired material. When the cover 150 is attached to the first hub 146, the cover 150 can apply pressure to the battery housing 206, which can secure the PCB 152 within the central hub 116. The battery 204 can be removably coupled to the battery housing 206. The battery 204 can be a lithium-ion battery or any other desired battery or power source. The battery housing 206 can have tabs or any other desired contact points for conducting electricity with the battery 204. The battery 204 can be removed from the battery housing 206 to shut down the goniometer 110 or replace the battery 204. For example, when the cover 150 is opened or removed from the first hub 146, the PCB 152 can be removed from the central hub 116 and the battery 204 can be replaced. To maintain calibration of the goniometer 110 after battery replacement, the inward recess 210 of the PCB 152 is configured to receive the outward recess 208 of the first hub 146 .

[0072] exist Figure 14C , the cover 150 and PCB 152 are removed from the central hub 116. As shown, the second hub 148 may include a magnet housing 224. The magnet housing 224 may be located in the center of the second hub 148 or at any other desired location. The magnet housing 224 may be coupled to the PCB 152 using welding, adhesive, tacks, or any other desired attachment. The magnet housing 224 may be configured to house the magnet 156. The magnet 156 may be configured to have a north and south pole or any other desired polarity within the central hub 116. The magnet housing 224 may include a lip on the top of the magnet housing 224 or have any other desired configuration. The retaining ring 154 may be configured to couple the magnet 156 to the second hub 148. The retaining ring 154 may surround the magnet housing 224 and couple to the second hub 148. For example, the retaining ring 154 may be located between an edge or top of the magnet housing 224 and the second hub 148. The retaining ring 154 can secure the magnet inside the magnet housing 224. The retaining ring 154 can be coupled to and move with the second hub 148, and the magnet 156 can rotate the second hub 148 with the second arm 130.

[0073] Figure 15A Shown is the top side 212 of the PCB 152. As described above, the battery housing 206 can be attached to the top side 212. Figure 15BThe bottom side 214 of the PCB 152 according to aspects of the present disclosure is shown. The PCB 152 includes components coupled to the bottom side 214. The components may include circuitry 220 including resistors, LEDs, transistors, capacitors, inductors, transducers, diodes, switches, sensors 216, transmitters 222, or any other desired components. The components may be attached to the PCB 152 using surface mount methods, through-hole methods, or any other desired methods. Likewise, the steps of these methods may be performed in a variety of different orders. The PCB 152 may include additional and / or fewer components and is not limited to the following. Figure 15A and Figure 15B Those shown.

[0074] The circuit 220 may be configured to generate an electrical signal based on the rotation of the magnet 156. The circuit 220 may be configured to transmit the electrical signal in real time. The circuit 220 may transmit the electrical signal. For example, the transmitter 222 may be coupled to the PCB 152 and configured to transmit the electrical signal to an external device based on the rotation of the magnet 156. The transmitter 222 may include a wired or wireless transmission, such as a Bluetooth®. TM , WiFi, NFC, or any other desired transmission means or method. The external device can be a mobile phone, a computer, a tablet computer, or any other desired device. The external device can have a user interface. The user interface can be configured to receive the electrical signal and display data obtained from the electrical signal. The data can include the angle of the joint 107 or any other desired information.

[0075] The user interface can include applications that receive data, manipulate data, record data, and display various aspects of the data. For example, the application can display the angle of the user's 102 joint 107, the history of the angle of the joint 107, the duration of the angle, or any other desired information such as real-time measurement of the angle.

[0076] The sensor 216 can be a Hall effect sensor or any other desired sensor (e.g., a magnetic position sensor AS5601 using an internal MEMS Hall effect sensor). The sensor 216 can be coupled to the PCB 152 or any other desired device. When the PCB 152 is disposed inside the center hub 116, the sensor 216 can be coupled to the bottom side 214 of the PCB 152 at a position directly above the magnet 156. The PCB 152 and the sensor 216 can rotate together with the first hub 146 and the first arm 128. The magnet 156 can rotate together with the second hub 148 and the second arm 130. The design of the wearable device 100, including the configuration of the sensor 216 and the magnet 156, can improve the measurement accuracy of the angle of the joint 107.

[0077] Figure 16Ais an exemplary graph 228 with a line 232 that depicts the accuracy with which the wearable device 100 measures the angle of the joint 107 when the wearable device 100 is attached to the user 102 . Figure 16B is an exemplary graphic 230 with lines 234 depicting the use of Velcro TM The accuracy of the angle of the joint 107 measured by the different measuring devices attached to the user by the strap. The standard deviation of the measurements made by the different measuring devices, shown by line 234, is greater than the standard deviation of the measurements made by the wearable device 100, shown by line 232. TM Compared to a wrist strap, a user, such as a clinician or patient, can more accurately initially place and realign the first accessory 118 and the second accessory 120 of the wearable device 100. The configuration of the first arm 128 and the second arm 130 of the wearable device 100 adapted to different users can increase measurement accuracy. The configuration of the components inside the central hub 116 of the wearable device 100 (including the PCB 152, the sensor 216, and the magnet 156) can further improve measurement accuracy. The wearable device 100 can be configured to measure the angle of the joint 107 with an accuracy of up to one hundredth of a degree. Different measuring devices may have an accuracy of up to 5 degrees. In other words, the measurements made by different measuring devices can have an accuracy of approximately + / - 5 degrees relative to the actual angle of the joint 107, such as an accuracy of approximately +1 / - 1 degree, or even an accuracy of approximately + / - 0.01 degrees.

[0078] As described elsewhere herein, the patch can be adhered to the skin. For example, a peel and place patch with consumable alignment arms and a center patch can help align the epicondyle center point of a user's knee joint with two points above and below for more precise placement.

[0079] 17A to 17E An embodiment of a walking monitor or pedometer 1701 is depicted. A version of pedometer 1701 can count the number of steps taken by a user, such as daily steps after surgery. Such a device can be carried by the user or attached to the user or to an external device of the user, such as a goniometer 110. Pedometer 1701 can be used to track the user's steps even if the user requires a walking aid or other assistive device.

[0080] In some versions, pedometer 1701 can be attached to the magnet of goniometer 110 to ensure accurate tracking of all steps taken by the user. Pedometer 1701 can include a metal element that is magnetically attracted to the magnet of goniometer 110. Alternatively, an additional magnet 1703 can be attached to pedometer 1701. Embodiments of pedometer 1701 can further include a body 1705, a removable cap 1707, a circuit board 1709 having one or more sensors (e.g., a motion sensor such as an accelerometer, a mechanical sensor) or other electromechanical sensors, a battery 1711, and fasteners 1713.

[0081] Figure 18 23 illustrate an embodiment of a knee brace 1800 according to aspects of the present disclosure. Figure 19 Shown Figure 18 Exploded view showing some subcomponents of the knee brace 1800. Figure 20 Shown Figure 18 Another exploded view showing some of the subcomponents of the knee brace 1800. Figure 21 Shown Figure 18 Picture of the components of the knee brace 1800. 22A to 22D A picture of a knee brace 1800 is shown on a user's leg. FIG. 23A to FIG. 23B A picture of the components of the knee brace 1800 being applied to the leg of a user is shown. Where "##(##)" notation is used, the numbers outside the brackets indicate the figure number and the numbers inside the brackets indicate the figure number as shown. For example, 19(1) refers to Figure 19 The part marked 1 in FIG.

[0082] The knee brace 1800 may include a calf strap 19(14), 20(8), 2304 for connecting the knee brace 1800 to the patient's calf. The calf strap 19(14), 20(8), 2304 may be connected to the lateral calf strut 19(1) via a hook pad 19(20). The calf strap 19(14), 20(8), 2304 may include a first set of features to align the brace with the patient's calf. For example, the calf strap 19(14), 20(8), 2304 may include a set of slits or holes in the calf strap 19(14), 20(8), 2304 and / or notches or cutouts (e.g., three holes or three notches) on an edge of the calf strap 19(14), 20(8), 2304 that allow a practitioner or patient to place a set of markings on the patient's calf. After the markings are placed on the patient's calf, the knee brace 1800 can be removed and reapplied to the patient's leg by aligning the holes or notches on the calf strap 19(14), 20(8), 2304 with the markings on the patient's calf.

[0083] The knee brace 1800 may further include thigh straps 19(6), 20(9), 2302 for connecting the knee brace 1800 to the patient's thigh. The thigh straps 19(6), 20(9), 2302 may be connected to the outer thigh support 19(13) via hook pads 19(20). FIG. 23A to FIG. 23B As shown, the thigh strap 19(6), 20(9), 2302 may include a system for aligning the brace with the patient's thigh. For example, the thigh strap 19(6), 20(9), 2302 may include a set of slits or holes in the thigh strap 19(6), 20(9), 2302 or notches or cutouts (e.g., five holes or five notches) on the edge of the thigh strap 19(6), 20(9), 2302 that allow the practitioner or patient to place a set of markings on the patient's thigh. After the markings are placed on the patient's thigh, the knee brace 1800 may be removed and reapplied to the patient's leg by aligning the holes or notches on the thigh strap 19(6), 20(9), 2302 with the markings on the patient's thigh. As Figure 23A and Figure 23B As shown, two sets of markings may be applied to indicate the maximum and minimum heights of the thigh strap 19(6), 20(9), 2302 to be applied to the thigh. Specifically, Figure 23A The thigh strap 19(6), 20(9), 2302 is shown to be applied too low on the thigh as indicated by the visible markings, and Figure 23B The proper height for application of the thigh strap 19(6), 20(9), 2302 on the thigh is shown, as indicated by a set of holes on the thigh strap 19(6), 20(9), 2302, which shows the blank skin in the space between the two sets of markings.

[0084] The lateral hinge includes a lateral calf brace 19(1) and a lateral thigh brace 19(13). The lateral calf brace 19(1) and the lateral thigh brace 19(13) can rotate relative to each other and are separated by a lateral brace washer 1902. The lateral hinge includes a lateral hub 19(21), 2102, which contains components of a device such as an electronic device (e.g., a goniometer, a pedometer, etc.). These components may include sensors, circuit boards 19(3), 2104, and a battery 19(2). As previously described, the lateral hub 19(21), 2102 can be formed similarly to the first hub 146 and perform a similar function. The lateral hub 19(21), 2102 can be connected to the lateral calf brace 19(1) and fixed relative to the lateral calf brace 19(1). The circuit board 19(3), 2104 can be used as the PCB 152 and can include components of the PCB 152 (e.g., can be configured to generate an electrical signal based on the movement of a magnet, can be configured to transmit an electrical signal, can include a transistor, etc.). The sensor can be used as the sensor 216 and can include components of the sensor 216 (e.g., the sensor can be a Hall effect sensor, the sensor can be connected to the circuit board 19(3), 2104, etc.). The lateral calf strut 19(1) can be connected to the lateral hub 19(21), 2102. The lateral cap 19(8) can be fastened to the lateral hub 19(21) 2102 and its contents and provide protection thereto using a pair of fasteners 19(5), 19(11). In an embodiment where the knee brace 1800 includes a pedometer, the pedometer can function as the pedometer 1701 and can include components of the pedometer 1701. The lateral thigh strut 19(13) can be connected to the lateral pad receiver 19(9) by a pair of fasteners 19(22). An alternative embodiment of the outer liner receiver 19 (9) is Figure 21 Shown as element 2110. Fasteners can enable the two parts of the central hub assembly to rotate on a central axis. The fasteners can be used in slots to allow rotation. Magnets 19(4), 2106 can be connected to the lateral thigh strut 19(13) to interact with the sensor and allow the goniometer to detect changes in the angular position of the knee brace 1800 and therefore the patient's knee joint. The lateral support washer 1902 can include a central feature for accommodating the magnets 19(4), 2106. The magnets 19(4), 2106 in the goniometer can help determine the angle of the device with the Hall effect sensor. A knee pad 19(7) for contacting the outside of the patient's knee joint can be connected to the lateral pad receiver 19(9). A stop pin 19(10), 2108 passes through a slot in the lateral calf strut 19(1) and into one of a series of holes in the lateral thigh strut 19(13) to adjustably limit the range of motion of the patient's knee joint.

[0085] The knee brace 1800 may further include a medial hinge, which may include a medial calf post 19 (17) and a medial thigh post 19 (16), each of which may be connected to a medial cuff pad 19 (15) via a hook pad 19 (20). The medial cuff pad 19 (15) may be connected to the thigh straps 19 (6), 20 (9), 2302 and the calf straps 19 (14), 20 (8), 2304, respectively. The connection may be made using hook and loop fasteners. This may be done manually on the inside of the affected knee joint. The connection increases the stability of the brace and assists in positioning stability. The medial calf post 19 (17) and the medial thigh post 19 (16) may be separated by a medial brace washer 19 (18) (e.g., a second washer). The medial hinge may further include a medial pad receiver 19 (19) that may be connected to the medial calf post 19 (17). One or more fasteners 1904 may extend through central holes in the medial pad receiver 19 (19), the medial calf strut 19 (17), the medial support washer 19 (18), and the medial thigh strut 19 (16) and secure them together. A knee pad 19 (7) for contacting the inside of the patient's knee may be attached to the medial pad receiver 19 (19).

[0086] The knee brace 1800 may further include integrated pockets for holding ice packs to reduce swelling in the patient's knee, located on or around the lateral hinge, medial hinge, calf lateral post 19(1), thigh lateral post 19(13), calf medial post 19(17), thigh medial post 19(16), calf straps 19(14), 20(8), 2304, and / or thigh straps 19(6), 20(9), 2302. In some embodiments, the integrated pockets are sealed and waterproof, allowing ice to be inserted directly into the integrated pockets and reducing external condensation near the ice packs. The knee brace 1800 may further include a connector for connecting an ice pack to the knee brace to reduce swelling of the patient's knee joint, which is located on or around the lateral hinge, the lateral hinge, the lateral calf column 19 (1), the lateral thigh column 19 (13), the medial calf column 19 (17), the medial thigh column 19 (16), the calf strap 19 (14), 20 (8), 2304 and / or the thigh strap 19 (6), 20 (9), 2302.

[0087] Figure 20 This is an exploded view of the soft goods used for the brace. In the center, the alignment device also sits on the epicondyle of the knee and wraps around the knee horizontally above and below the user's incision. This can be used to align the brace.

[0088] It should be understood that the components of the knee brace can be rearranged and include more components or fewer components without departing from the present disclosure. An example of such rearrangement includes moving the goniometer from the lateral hinge to the medial hinge. In some versions, the medial hinge is only for stability. The brace can be available in left and right leg versions. The goniometer can be located on the lateral side of the knee joint. In accordance with the teachings of the present disclosure, other examples can include a hub (containing the goniometer) that contacts the thigh strut rather than the calf strut, and form braces for other joints (e.g., an elbow brace for an elbow joint that includes one or more forearm struts and one or more upper arm struts, a universal brace for a universal joint that includes one or more lower joint struts and one or more upper joint struts).

[0089] Figure 24 An embodiment of a system 2400 for securing a goniometer to a user's leg is illustrated. Some versions of system 2400 may include a slot target template 2402, a goniometer 2404, a knee pivot anchor 2406, a pair of anchor slots 2408, a set of four-point stickers 2410, a surgical marker 2412, and four alcohol prep pads 2414. The example goniometer 2404 may include a pair of goniometer arms 2416, 2420, each of which may include one or more goniometer arm magnets or ferromagnetic material.

[0090] Figure 25 Figures 25A and 25B illustrate in greater detail perspective views of an example of a slot target template 2402. The slot target template 2402 can have a proximal end 2502 and a distal end 2504. A knee pivot hole 2506 for receiving and connecting a knee pivot anchor 2406 can be included and can be located near the proximal end 2502 of the slot target template 2402. A triangular tip 2508 can extend from the distal end 2504 of the slot target template 2402. A longitudinal axis L can pass through the centerline of the slot target template 2402. The slot target template 2402 can further include one or more rows of viewing holes 2510 along the slot target template 2402 to facilitate viewing of physiological target markers on shorter individuals. Figure 25 The slot target template 2402 is shown to have two rows of visible holes 2510, but as Figure 29H and 29I A row (or more than two rows) of visible holes is also contemplated. Holes or slot receiving holes 2512 for receiving and connecting to the anchor slot 2408 can be defined in the slot target template 2402. Slot receiving tabs 2514 can be placed along the outside of the slot receiving holes 2512 and facilitate securing the anchor slot 2408 in place.

[0091] Figures 26A to 26E A perspective view of an example of a knee pivot anchor 2406 is shown in greater detail. Figure 26Eis an exploded perspective view. The knee pivot anchor 2406 can include a flat disk structure 2602 having indentations 2604 extending inwardly. Since the knee pivot anchor 2406 is intended to be secured to a generally uneven surface (i.e., the side of a person's knee), the indentations 2604 can be used to reduce material requirements and increase the flexibility of the flat disk structure 2602. A set of anchor tabs 2606 can extend upward from near the center of the flat disk structure 2602. The anchor tabs 2606 can be used to connect the knee pivot anchor 2406 to the slotted target template 2402. An anchor hole 2608 can be defined in the center of the knee pivot anchor 2406 to allow a user to align the knee pivot anchor 2406 with a marker placed on a person's skin. A knee pivot adhesive pad 2610 can be secured to the flat disk structure 2602 to secure the knee pivot anchor 2406 to a person's knee. The knee pivot backing 2612 can cover the adhesive on the knee pivot adhesive pad 2610 until it is peeled off, thereby preventing the adhesive from being inadvertently attached to the wrong surface. The anchor hole 2608 can also extend through the knee pivot adhesive pad 2610 and the knee pivot backing 2612.

[0092] Figures 27A to 27C An example of one of the anchor slots 2408 is illustrated in more detail, wherein Figure 27Cis an exploded perspective view. Each anchoring slot 2408 can include a receiving module 2702 for engaging and connecting with the goniometer arms 2416, 2420. The receiving module 2702 can include a magnet 2704 or ferromagnetic material for attracting or being attracted to the magnet or ferromagnetic material of the goniometer arms 2416, 2420. The receiving module 2702 can also include a central structure 2706. The central structure 2706 can be connected to the receiving module 2702 using a first slot adhesive layer 2708. A second slot adhesive layer 2709 can be connected to the other side of the central structure 2706. A first slot backing portion or half 2710 and a second slot backing portion or half 2712 can each cover a portion of the second slot adhesive layer 2709, with the first slot backing half 2710 overlapping and covering a small portion of the second slot backing half 2712. Although the term "half" is used, each slot sheet backing 2710, 2712 can have different sizes and cover more or less than half of the second slot sheet adhesive layer 2709. A first backing 2714 (labeled "1") can be attached to the first slot sheet backing 2710 to facilitate removal of the first slot sheet backing 2710 from the second slot sheet adhesive layer 2709. A second backing 2716 (labeled "2") can be attached to the second slot sheet backing 2712 to facilitate removal of the second slot sheet backing 2712 from the second slot sheet adhesive layer 2709. The removal process involves using the first backing sheet 2714 to remove the first slot sheet backing half 2710, and then using the second backing sheet 2716 to remove the second slot sheet backing half 2712. Four notches 2718 are defined around the perimeter of the second slot sheet adhesive layer 2709 and in portions of the first slot sheet backing half 2710 and the second slot sheet backing half 2712. These notches 2718 can be used as guides to align the anchors 2408 during reapplication by marking the skin around the notches 2718 using the surgical marker 2412 and placing the anchors 2408 during reapplication so that the marks align with the notches 2718. Each anchor 2408 can be stored in an assembly bag 2720 prior to use.

[0093] It is understood that the components of the system 2400 can be rearranged to include more or fewer components without departing from the present disclosure. Examples of such rearrangements include having more or fewer intermediate layers or integral components in the anchor slot 2408, and using different connection means between the anchor slot 2408 and the slot target template 2402.

[0094] like Figures 28A to 28C As shown, an embodiment of a method 2800 for securing a goniometer to a person's leg is disclosed. As described below, Figures 29A to 29L Another embodiment of steps that may be performed is described.

[0095] exist Figure 28AStep 2802 in Figure 29A As depicted, method 2800 may include cleaning a person's legs. This may include cleaning between 10 inches (25.4 centimeters) or more above and 10 inches (25.4 centimeters) or more below the side of the person's knee. Cleaning may be accomplished using an alcohol prep pad, such as alcohol prep pad 2414.

[0096] In step 2804, if Figure 29B As shown, method 2800 may include marking a bony knee pivot 2902 on the outside of the knee joint (i.e., the lateral epicondyle). The bony knee pivot 2902 may be marked as a point on the skin closest to the widest part of the bony structure of the knee. The bony knee pivot 2902 may be marked with a marking pen or other writing device, such as a surgical marking pen 2412.

[0097] In step 2806, if Figure 29C As shown, method 2800 may include marking a bony hip joint 2904 (i.e., the greater trochanter). Bone hip joint 2904 may be marked at the widest point above the person's hip joint. Bone hip joint 2904 may be marked with a sticker placed on the person's clothing, such as one of dot-shaped stickers 2410. If possible, the person should avoid walking after application because the sticker is on the person's clothing, which may move relative to the person's bony hip joint 2904.

[0098] In step 2808, if Figure 29D As shown, method 2800 may include marking a bony ankle joint 2906 (i.e., the outer thigh). Bone ankle joint 2906 may be marked at the widest bony point on the outer side of the person's ankle. Bone ankle joint 2906 may be marked with a sticker, such as one of dot stickers 2410, or a marker or other writing device, such as surgical marker 2412. If the marker is a sticker on the person's sock, it should be applied if possible because the sock may move relative to the person's bony ankle joint 2906, so the person should avoid moving.

[0099] In step 2810, if Figure 29E As shown, the method 2800 may include placing the knee pivot anchor 2406 into the knee pivot hole 2506 of the slot target template 2402. This may be accomplished by a snapping action of the anchor plate 2606 within the knee pivot hole 2506.

[0100] In step 2812, also as Figure 29EAs shown in , method 2800 may include placing an anchor tab 2408 into a tab receiving hole 2512 of a tab target template 2402. The anchor tab 2408 may be secured in place using two tab receiving tabs 2514 and four cantilevered snap features 2516 located next to the two tab receiving tabs 2514.

[0101] At step 2814 , method 2800 may include peeling the knee pivot backing 2612 away from the knee pivot anchor 2406 to expose the knee pivot adhesive pad 2610 .

[0102] In step 2816, if Figure 29F As shown, the method 2800 may include centering the knee pivot anchor 2406 on the bony knee pivot 2902, as marked in step 2804, and pressing the knee pivot adhesive pad 2610 into contact with the bony knee pivot 2902. Centering may be accomplished by viewing the markings of the bony knee pivot 2902 through the knee pivot hole 2506 and the anchor hole 2608.

[0103] In step 2818, if Figure 29G As shown, the method 2800 may include aligning the longitudinal axis L of the slot target template 2402 with a marker of the bony hip joint 2904 such that the longitudinal axis L passes through both the bony knee joint pivot 2902 and the bony hip joint 2904. A row of viewing holes 2510 facilitates alignment of the bony hip joint 2904 in shorter patients. A triangular tip 2508 facilitates alignment of the bony hip joint 2904 in taller patients.

[0104] In step 2820, also as Figure 29G As shown in , the method may include pressing the anchor slot 2408 into contact with the person's thigh.

[0105] In step 2822, also as Figure 29G As shown, the method 2800 may include removing the first slot sheet backing half 2710 by pulling on the first backing 2714 and pressing the now exposed half of the second slot sheet adhesive layer 2709 into contact with the patient's thigh.

[0106] At step 2824, method 2800 can include removing the slot target template 2402 from contact with the anchor slot 2408 while leaving the anchor slot 2408 on the patient's thigh. Removal can be accomplished by applying force to the slot receiving tab 2514 to release the anchor slot 2408.

[0107] At step 2826, the method 2800 may include removing the second slot backing 2712 by pulling the second backing 2716 and pressing the anchor slot 2408 into contact with the patient's thigh.

[0108] At step 2828, the method 2800 may include placing another anchor tab 2408 into the tab receiving hole 2512 of the tab targeting template 2402. The anchor tab 2408 may be secured in place using the tab receiving tab 2514.

[0109] In step 2830, if Figure 29H As shown in FIG, method 2800 may include aligning the longitudinal axis L of the slot target template 2402 with a marking of the bony ankle joint 2906 such that the longitudinal axis L passes through both the bony knee joint pivot 2902 and the bony ankle joint 2906. A row of viewing holes 2510 facilitates alignment of the bony ankle joint 2906 on shorter patients. A triangular tip 2508 facilitates alignment of the bony ankle joint 2906 on taller patients.

[0110] At step 2832, the method may include pressing the anchoring slot 2408 into contact with the patient's lower leg.

[0111] At step 2834, the method 2800 may include removing the first slot flap backing half 2710 by pulling on the first backing 2714 and pressing the now exposed half of the second slot flap adhesive layer 2709 into contact with the patient's calf.

[0112] In step 2836, if Figure 29I As shown, method 2800 may include removing the slot target template 2402 from contact with the anchor slot 2408 while leaving the anchor slot 2408 on the patient's calf. Removal may be accomplished by applying force to the slot receiving tab 2514 to release the anchor slot 2408.

[0113] At step 2838, the method 2800 may include removing the second slot backing 2712 by pulling on the second backing 2716 and pressing the anchor slot 2408 into contact with the patient's calf.

[0114] At step 2840, the method 2800 may include removing the knee pivot anchor 2406 from the slot-piece target template 2402. Removal may be accomplished by applying force to the anchor sheet 2606 to slide the anchor sheet through the knee pivot hole 2506.

[0115] At step 2842, method 2800 can include removing the knee pivot anchor 2406 from the person's knee joint. This can be done by gently peeling the knee pivot anchor 2406 away from the person's knee joint.

[0116] In step 2844, if Figure 29J As shown, the method 2800 may include flattening the second slot adhesive layer 2709 of each of the anchor slots 2408 and gently rubbing to ensure a complete bond with the person's leg.

[0117] In step 2846, if Figure 29K As shown, the method 2800 may include marking the skin with respect to the notch 2718. The marking may be done with a pen or other writing instrument, such as a surgical marker 2412. Marking with a surgical marker 2412 will ensure that the marking remains visible if the patient showers before reapplying the anchor 2408.

[0118] In step 2848, if Figure 29L As shown, the method 2800 may include coupling the goniometer 2404 to the anchoring slot 2408. The goniometer 2404 may be coupled by bringing goniometer arm magnets or ferromagnetic material in the goniometer arms 2416, 2420 into proximity with the anchoring slot magnets and snapping the goniometer arms 2416, 2420 and the anchoring slot 2408 together.

[0119] Embodiments of method 2800 are not limited to the steps disclosed and may include more or fewer steps than those disclosed. Certain steps may be omitted (e.g., step 2840 may be skipped entirely and the knee pivot anchor 2406 may be removed from the patient's knee joint while still connected to the slot target template 2402). These steps may be performed in any suitable order (e.g., steps 2818 to 2826 of placing one of the anchor slots 2408 on the person's thigh may be performed before or after steps 2830 to 2838, but step 2804 of marking the bony knee pivot may not be performed after step 2816 of placing the knee pivot 2406 in contact with the knee pivot 2902).

[0120] Figure 30A and Figure 30B A top view of an alternative embodiment of a slot target template 2402 is illustrated. As previously described, the slot target template 2402 can include a single row of viewing holes 2510. The length of the slot target template 2402 can vary. These versions of the slot target template 2402 can be used in the same or similar manner as the other versions described herein.

[0121] Figure 31 Another embodiment of a system 2400 is illustrated having eight anchor slots 2408 and two slot target templates 2402. The two slot target templates 2402 have different lengths and can be used in the same or similar manner as the other versions described herein.

[0122] Figure 32A system 3200 is shown for determining the angle A of a user's joint. The system may include two accelerometer slots 3202 including accelerometers. As shown, one of the accelerometer slots 3202 is placed on the user's upper leg, while the other accelerometer slot 3202 is placed on the user's lower leg. In some embodiments, one or both of the accelerometer slots 3202 may include a wireless network device (e.g., a Bluetooth device). In some embodiments, the accelerometer slots 3202 may communicate wirelessly with each other via their respective wireless network devices. In some embodiments, one or both of the accelerometer slots 3202 may communicate with a remote computing device 3204 via their respective wireless network devices. The accelerometers may be used to determine the direction of the accelerometer slots 3202 relative to gravity, transmit this direction to each other or to the remote computing device 3204, and allow the angle A of the user's joint to be determined.

[0123] As previously discussed in this disclosure regarding the anchor slot 2402, the accelerometer slot 3202 can be connected in the same manner and using the same methods. The accelerometer slot 3202 can utilize a strap placed near the leg, such as an elastic thigh strap or calf strap. Using the accelerometer slot 3202 can allow for reduced complexity and size.

[0124] Accelerometer slot 3202 may include one or more memory devices in communication with the accelerometer. In some embodiments, the one or more memory devices may be in communication with a wireless network device. The memory devices may be used to store directional information for subsequent transmission to a remote computing device 3204. In some embodiments, accelerometer device 3202 may include a battery for powering various subcomponents.

[0125] As shown in Figures 33-34, the accelerometer slot 3202 can include a main body portion 3302 and an adhesive portion 3304. A release liner 3305 can be removed from the adhesive portion 3304 to expose the adhesive, thereby securing the main body portion 3302 to the user. The accelerometer slot 3202 can further include a first end 3306 and a second end 3308, each formed such that the first end 3306 of the first accelerometer slots 3402a and 3402b can engage with the second end 3304 of the second accelerometer slots 3402c and 3402d. For example, as shown in Figures 33-34, the first end 3306 can be formed concavely, while the second end 3308 can be formed convexly, such that the first ends 3306 of the first accelerometer slots 3202a and 3402b can engage with the second ends 3308 of the second accelerometer slots 3402c and 3402d without a substantial gap. In other words, the first and second ends 3306, 3308 can be complementary in shape to each other so that they can nest or fit tightly together. Other shapes (e.g., chevron-shaped or wavy ends) can be used for the first and second ends 3306, 3308 while still allowing the first end 3306 of the first accelerometer slot 3402 to engage with the second end 3308 of the second accelerometer slot 3406 without any substantial gap therebetween.

[0126] Figure 34A The two first accelerometer slots 3402a, 3402b are shown initially connected to the thigh and calf respectively. These can be connected as previously described with respect to the anchor slot 2408.

[0127] Figure 34B Two second accelerometer slots 3402c and 3402d are shown attached to the thigh and calf, respectively. Just before removing the two first accelerometer slots 3402a and 3402b, the two second accelerometer slots 3402c and 3402d (identical to the two first accelerometer slots 3402a and 3402b) are positioned to engage with the respective two first accelerometer slots 3402a and 3402b, such that the first ends 3306 of the two first accelerometer slots 3402a and 3402b engage with the second ends 3308 of the second accelerometer slots 3402c and 3402d without any substantial gap therebetween (e.g., they may abut one another). Thus, a user can position the second accelerometer slots 3402c and 3402d without professional assistance while maintaining the alignment of the originally installed first accelerometer slots 3402a and 3402b. The user may then remove the first accelerometer slots 3402a, 3402b to allow the user's skin underneath them to breathe and avoid maceration.

[0128] Figure 34CTwo third accelerometer slots 3402e, 3402f (similar to the two first accelerometer slots 3402a, 3402b and the second accelerometer slots 3402c, 3402d) are illustrated as being connected to the thigh and calf, respectively. The two third accelerometer slots 3402e, 3402f are positioned to engage with the respective two second accelerometer slots 3402c, 3402d, such that the first ends 3306 of the two third accelerometer slots 3402e, 3402f engage with the second ends 3308 of the second accelerometer slots 3402c, 3402d without any substantial gap therebetween (e.g., they may similarly abut one another). The user can then remove the second accelerometer slots 3402c, 3402d to allow the user's skin underneath them to breathe and avoid immersion. This technique and method of replacing slots 3402a, 3402b, 3402c, 3402d, 3402e, 3402f can be repeated as needed.
