Patent Application
20180296875
The present application is directed to systems for therapeutically treating the hand of a patient. In particular, the present application is directed to a multi-part kit integrated into a case, housing or enclosure adapted for providing physical therapy for a hand in a home setting with little or no active participation by a professional therapist during its use including with a computer-driven guide for enhanced operation.
Currently, a patient that needs physical therapy for her hand needs to go to a professional office, such as a doctor's office or a physical therapist's office, to receive treatment. This can be a significant undertaking for a patient that needs to travel a long distance, take time away from work, and/or secure childcare so that she can attend a physical therapy appointment at a professional office. This undertaking is compounded by the number of sessions the patient needs to attend, which can often repeat over multiple weeks or months.
In addition, patients are often frustrated because many of the exercises that they perform with a professional physical therapist could be done at home at a more convenient time and without unnecessary travel. Indeed, some exercises only require the use of common household objects such as rubber bands or clothespins. What is needed is a kit that contains therapeutic objects for home-based physical therapy of the hand.
The present disclosure is directed to a device and a kit for home-based physical therapy of the hand. The present devices and systems overcome many of the shortcomings of existing devices and systems for treating the hand. In an aspect, the present device can improve strength and/or range of motion of the hand including the fingers thereof. The device and kit include an elastic cord attached to a rigid surface at two or more contact points to define a gap for receiving a finger. A finger can be inserted in the gap and moved form a first position proximal to the rigid surface to a second position distal to the rigid surface for a therapeutic exercise. The kit can also include a therapeutic tracking glove and/or a pressure sensor ball.
An aspect of the invention is directed to a hand therapy kit comprising: a housing that includes a lid, wherein said lid is expandable from a folded configuration to an unfolded configuration to expose a working surface on an inside of said lid; an elastic cord attached to said working surface, said elastic cord defining a first gap between a first anchor point and a second anchor point on said working surface, said first gap sized to receive a first finger, said elastic cord defining a second gap between a third anchor point and a fourth anchor point on said working surface, said second gap sized to receive a second finger, wherein said elastic cord is configured to provide a first positive resistance as said first finger moves from a first position proximal to said working surface to a second position distal to said working surface and said elastic cord is configured to provide a second positive resistance as said second finger moves from said first position to said second position; and a plurality of removable hand therapy modules disposed in said housing, said plurality of hand therapy modules including: a therapeutic elastic band module, said therapeutic elastic band module comprising a plurality of therapeutic elastic bands having different resistances for progressively exercising a hand; a wrap module comprising a stretchable fabric adapted to wrap around said first finger to apply a therapeutic pressure thereto; and a therapeutic tracking glove comprising: a plurality of rotational position sensors attached at positions on fingers of said therapeutic tracking glove that correspond to respective joints of a user's finger; and a plurality of rods, each rod extending between adjacent rotational positional sensors and in mechanical communication therewith.

For a fuller understanding of the nature and advantages of the present concepts, reference is made to the following detailed description of preferred embodiments and in connection with the accompanying drawings, in which:
A hand therapy kit includes a housing having a lid that is expandable from a folded position to an unfolded position to expose a working surface on an inside of the lid. An elastic cord is attached at two or more anchor points on the working surface to define at least one gap for receiving a finger. The finger can be therapeutically exercised by moving from a first position proximal to the working surface to a second position distal to the working surface. The hand therapy kit can also include removable hand therapy modules.
In another aspect, an apparatus for providing home-based physical therapy to a hand is disclosed. The apparatus includes an elastic cord attached to a rigid platform at two or more contact points. The contact points define a gap therebetween for receiving a finger. The finger can be therapeutically exercised by moving from a first position proximal to the rigid platform to a second position distal to the rigid platform.
The hand therapy kit and apparatus can be used by patients to provide physical therapy in a home environment. This provides a more convenient and cost-effective solution for the patient. By using the hand therapy kit and apparatus, the patient can improve strength, dexterity, and/or range of motion of his hand and fingers. Also, use of the kit can reduce healthcare costs and individual patient costs by allowing the user to participate in physical therapy at home with minimal to no involvement by medical personnel (e.g., doctors, physical therapists, etc.) and minimal to no use of medical offices.
The kit can include a camera and a processor for motion recognition. The motion recognition system can include instructions to compare the user's exercise techniques with model exercise techniques to provide feedback to the user. In addition or in the alternative, the kit can include equipment for video calls, such as a display, a processor, a video camera, and a network interface. The user can make video calls with a healthcare provider for instruction, monitoring of the user's progress, and/or health appointments. In addition or in the alternative, the video camera can record the user's exercises for therapists and doctors to use to treat the user and/or research purposes.
The kit can also include a therapeutic tracking glove and/or a pressure sensor ball. The tracking glove includes sensors to measure the range of motion of the user's hand, including the finger joints and wrist. The pressure sensor ball includes an inner spherical body disposed in a compressible ball. A plurality of radial force sensors are distributed across the external surface of the spherical body to measure any force that is applied to the corresponding external surface of the compressible ball to which the radial force sensors are aligned.
Data from the therapeutic tracking glove and/or a pressure sensor ball can be sent via a wired or a wireless communication interface to an external device, such as a user's mobile device. The user's mobile device can include an application or app that can process and analyze the received data and to present the data to the user to track his/her progress. The application or app can also allow the user to send the data, in raw or modified form, to a third party such as his/her physical therapist. Therefore, the kit can include in some embodiments a system or sub-system for data collection and transmission, e.g., wired or wirelessly, to exchange or provide information, e.g., to and/or from a separate module or computing system or network-connected server, which in turn may be coupled to or include a data processor, memory device or database, and may be adapted to execute machine readable instructions. This data communication can be facilitated by software and hardware and using special or general data communication protocols. Connection may be established with connected or networked devices, including mobile communication devices, smart phones, computer systems, gaming consoles and the like.
In some aspects, the data connectivity features may be enabled and used through hardware and/or software user interfaces, e.g., on a user's mobile device running a local or web-based application. The mechanical exercise modalities will contain sensory input components which will be able to collect and transmit the data. The nature of the data will be various measurements and progress trackers analogous to the measurements taken by a certified hand or occupational therapist. The application itself can utilize various different technologies including but not limited to digital motion sensor capabilities and cluster recognition algorithms for injury measurements (using the device's camera), audio commands from both the app and from the user, video and audio calling interfaces for one on one conversations with the therapist, and comprehensive tutorial videos.
Additionally, the application can include a community based comparator with a point system to incentivize progress checkpoints for therapy. It can also incorporate FAQs and forums for patients to talk with each other and with professionals other than their therapist. The present system and method can allow an effective and comfortable vehicle for hand therapy inside one's own home without the need to travel to a practitioner's location, seek parking, navigate unfamiliar facilities (especially if the patient is infirm or disabled), and without sacrificing the abilities of the physician and therapist to track progress and adapt treatment strategies.
In order to make the integration with this mobile/web application easier and more quantitative, the present invention may include a plurality of (e.g., two) sensory input devices for measurement of various hand, finger, and wrist quantities. One of these comes in the form of a glove that houses sensors necessary to measure movements in a comprehensive and accurate manner. The other is a grip and/or pinch strength measurement device utilizing radial sensors housed in a spherical or alternately shaped containment. Both can transmit wireless/wired data as discussed above, and may be coupled to a communication and processing circuit including a virtual reality (VR) system as appropriate.
In an embodiment, a patient may be provided with a wearable headset coupled to a VR interface presenting visual information to the patient. The patient could be presented through the VR with imagery in the visor of the headset, the imagery presenting for example a scene with the patient interacting virtually with a professional trainer, and the patient can see an image or representation in the VR display representing the patient's hand as well. This virtual hand tracking process may take inputs from one or more sensors, signals such as those described herein. For example, sensors measuring force, position, relative extension, speed, and other physical parameters can be used to acquire information to guide the therapy. The system generates information to create the virtual representation of the patient's hand for display in the VR headset. It should be appreciated that such data and imagery can be sent to a variety of processor based components of a therapy system, and stored for the patient's records in a memory unit, or otherwise shared with human or artificial therapists. Instructions to the patient and indications of success or necessary therapy steps can be generated and displayed visually or audibly through the VR interface.
In some embodiments, an optional heating element 250 is integrated into the upper lid 200 and/or lower lid 210, for example on one of the working surfaces 225, 235 or on one of the lower surfaces 205, 215. The element 250 can be used to warm paraffin wax (e.g., from the paraffin wax module 530C described below). The heating element 250 can be powered by a battery stored in the kit 20 or by external AC power provided through an electric cord 255, which can be integrated into the kit 20. In an embodiment, the housing or case of the kit can include an integrated AC power plug or connector so that the kit can accept an ordinary AC power extension cord to provide heating or other power to the units within the kit, e.g., as described below. For example, the electric cord 255 can pass through the inside of the kit 20 and out through a sidewall 240 of the kit 20. The electric cord 255 can be retractable so that it can be stored inside the kit 20. In some embodiments, the heating element 250 is disposed on a surface below the working surface 225, 235 in which case the working surface 225, 235 is removable so that a user can access the heating element 250.
In operation, a patient inserts one or more fingers 350 in respective gaps 340. The finger(s) 350 are inserted so that the finger pad(s) 360 are exposed while the finger nail(s) (not shown) are adjacent to the surface 320. The patient bends the finger(s) 350 away from the surface 320 generally in a direction 370 (from a proximal to a distal position). As the patient bends the finger(s) 350, the elastic cord 310 provides a positive resistance for exercising and/or strengthening the finger(s) 350. In an aspect, the cord (or cords if it is made of several individual loops) can have a textured and/or heated surface to enhance the therapeutic action of the cords.
In some embodiments, the surface 320 and/or rigid platform 380 is formed of wood, plastic, cardboard, or similar material that is generally inflexible so that the surface 320 and/or rigid platform 380 does not deform during use of the pulleys 300. In some embodiments, the pulleys 300 are formed from two or more elastic cords 310A, 310B, 310N. Each elastic cord 310A, 310B, 310N can have the same or different resistance and can be formed from the same or different materials. The pulleys 300 can be disposed as a component and/or module of a hand therapy kit as described herein. Alternatively, the pulleys 300 can be integrated onto a working surface of a kit, as described above.
In some embodiments, elastic cord 410 can be a single elastic cord that extends through each anchor point 430. The single elastic cord can pass through at least a portion of the block 440 to form each anchor point 430. For example, when the single elastic cord pass through to the underside of block 440, a portion 412 of the single elastic cord can be visible. Alternatively, elastic cord 410 can include multiple elastic cords, each elastic cord attached at two anchor points 430 to function as a pulley 400.
The kit 50 includes a housing 500 having an upper lid 510 and a lower lid 520 as generally described above. One or more modules 530 for providing home-based therapeutic treatment for the hand are disposed in the kit 50. As illustrated, the modules 530 include an elastic band module 530A, a wrap module 530B, a paraffin wax module 530C, a clothespin module 530D, a cold pack module 530E, a hot pack module 530F, a strap module 530G, a high-resistance putty module 530H, a low-resistance putty module 530I, a thimble module 530J, and a dexterity pad module 530K. Greater or fewer modules 530 can be disposed in the kit 50. In some embodiments, the modules 530 are removable and/or interchangeable.
The elastic band module 530A includes multiple elastic bands having different sizes, shapes, and/or elasticities and can be formed out of rubber (natural or synthetic), bungee cord, or similar material. The elastic band module 530A can be used by a patient to exercise the hand (or various portions of the hand such as one or more fingers, etc.) at different resistances. For example, a patient can place an elastic band over a clenched first for exercising the hand by opening and closing the first against a resistive force provided by the elastic band. Such exercise can increase intrinsic and/or extrinsic muscle strength as well as dexterity. Intrinsic muscles include those that originate and insert within the hand; extrinsic muscles have an origin outside of the hand (e.g., the forearm). The kit 50 and/or elastic band module 530A can include instructions for using the elastic bands. In some embodiments, the elastic bands are color coded by resistivity (e.g., darker-colored bands are more resistive and lighter-colored bands are less resistive).
The wrap module 530B includes an elastic bandage that can be self-adhering in some embodiments. The elastic bandage can be formed out of a stretchable and/or flexible material. In operation, a patient can wrap the elastic bandage around one or more fingers, for example in a distal (towards finger tip) to proximal (towards knuckle) direction, to reduce swelling and/or to guide edema. Such a wrapped elastic bandage can also promote lymphatic drainage. The kit 50 and/or wrap module 530B can include instructions for using the elastic bandage.
The paraffin wax module 530C includes a source of paraffin wax (e.g., a tub) and a bath unit, which includes a heater to heat and melt the paraffin wax. In some embodiments, the bath unit can be designed to heat the paraffin wax to between about 125° F. and about 135° F. In operation, a patient can place her hand (or portion thereof or other extremity) in the bath unit, which contains heated and melted paraffin wax. The heated paraffin wax warms the tissue in the hand/extremity to make it more supple, elastic, and/or flexible before and/or during exercises. Pre-treatment of the hand in the paraffin wax bath can improve pain and range of motion during exercises.
In addition or in the alternative, the paraffin wax module 530C includes a paraffin glove, which can be heated (e.g., in the microwave) and worn by a patient. Such a glove can warm the entire hand at once not only before exercise/therapy but also during exercise/therapy. The kit 50 and/or paraffin wax module 530C can include instructions for using the paraffin wax, bath unit, and/or paraffin glove. In some embodiments, the glove includes a material that is exothermic with stretch to provide warmth during use. The glove can be reusable or microwaveable or washable.
Also, a compression glove could be provided as part of the kit and that can serve to reduce swelling. Such a glove may be a one-size-fits-most and can have an elastic or stretchable material to stretch over hands of various sizes.
A glove may be employed in some embodiments that is designed and arranged to fit around the entirety of a patient's hand, fingers, and to extend over a certain area of the wrist. A first set of sensors therein may be longitudinal in design and run the length of each finger on the inner hand. These can meet at a central location either in the center of the palm, outside the back of the hand, or the base of the hand near the wrist. The glove sensors may comprise a few distinct components as described herein.
For example, a first set of components of the glove system may be fixed parts on the inside of the hand. Similar to how a nerve runs through a tunnel, there would be fixed guided pathways running up the length of each finger.
In some aspects, one or more or every joint of the finger may comprise a hinge so that the pathway could bend without restricting the finger. These hinges would have a mechanical component like a dial or tick that shift position as that specific joint was flexed or extended. This would function as a goniometer. The goniometer could measure range of motion, ranging from 0 degrees to 90 degrees at the distal interphalangeal joint, 0 to 100 degrees at the proximal interphalangeal joint, and 0 to 100 degrees at the metacarpophalangeal joint. At the wrist level, the sensors could detect range of motion from 90 degrees of dorsi flexion, or wrist extension to 90 degrees of palmar flexion, or wrist flexion. The component's position would indicate an angle or a particular type of finger movement. The data received from these sensors would be transmitted to a recording device, either through wireless or wired means. This data would then be stored and organized using an algorithm encoded in a sequence of machine-readable program instructions executed on a processing circuit that categorizes the information. This information could then be referred back to or communicated to the physician or therapist, in order to monitor progress and help patients achieve targets or goals. This information would also enable better patient compliance as it would serve as a direct feedback of progress in various parameters.
In some examples, to transfer the mechanical inputs into electrical outputs for data transfer and analysis, the system comprises small wires running within the elastic bands. This way the current could be changed by hinge movement or overall extension, and thus, there would also be some electrical data to interpret.
A second set of glove sensors are longitudinal in design and run the length of the back of the hand and extend over the wrist. Similar to the sensors running along the palmar aspect of the hand, the dorsal sided sensors can be used in concert to fine tune the measurements, as they would be the supplement of the palmar sensor measurements.
Yet a third set of glove sensors could be located within the interior of the glove on the inside of the hand which can relay thermal output.
In the figure shown, the clothespin module 530D includes one or more clothespins and optionally a string, fabric, or other object for attaching clothespins thereto. In operation, a patient uses her fingers to open the clothespins and attach them to the string, fabric, or other object. Such an exercise can improve the strength of the patient's fingers (e.g., the “pinch” strength) as well as her dexterity. The kit 50 and/or clothespin module 530D can include instructions for using the clothespins.
The cold pack module 530E includes one or more cold packs, which can come in a variety of forms such as a flexible cold pack (e.g., containing a gel or beads), a rigid cold pack, etc. The cold pack can be cooled by placing it in a refrigerator or freezer unit. Alternatively, the cold pack can be cooled by inserting ice and/or a cool liquid in an internal cavity defined by the cold pack. In operation, a patient places the cold pack on a body part (e.g., the hand) before or after exercising the body part to reduce swelling and/or reduce pain. The kit 50 and/or cold pack module 530E can include instructions for using the cold packs. The cold pack can be reusable.
The hot pack module 530F includes one or more hot packs, which can come in a variety of forms such as a flexible hot pack (e.g., containing a gel or beads), a rigid hot pack, etc. The hot pack can be warmed by heating it in a microwave or with an electric current. Alternatively, the hot pack can be warmed by pouring a warm liquid (e.g., hot water) into an internal cavity defined by the hot pack. In operation, a patient places the hot pack on a body part (e.g., the hand) before or after exercising the body part to improve flexibility and/or range of motion. The kit 50 and/or hot pack module 530F can include instructions for using the hot packs.
In some embodiments, the cold pack module 530E and the hot pack module 530F are integrated into a single module. For example, the integrated hot/cold pack module can include a thermal pack with a gel that stays hot when heated (e.g., in the microwave) and that stays cool when cooled (e.g., in the freezer). Alternatively, the hot/cold pack module can be a smart material that produces heat when stretched and cools when compressed.
The strap module 530G includes a strap made out of a fabric, such as a nylon or polyester. In operation, a patient can wrap the strap around an object and exercise her hand muscles (e.g., the grip muscles) by pulling on the strap. In some embodiments, the patient can secure the strap in a door jam. In addition or in the alternative, a patient can pull opposing ends of the strap to exercise both hands at the same time. The kit 50 and/or strap module 530G can include instructions for using the straps. In an aspect, a multi-strap finger exercise module allows for exercising of one or more fingers, for example simultaneously. The straps may be elastic or spring loaded from beneath, or may be otherwise mechanically resistive to elongation when under tensile stress. Strength and dexterity of the fingers and of associated hand muscles and tissues is achievable through a regimen of exercise using the elastic strap module 530G.
The high-resistance putty module 530H and low-resistance putty module 530I include various containers or pellets of therapeutic putty having various resistances. The putty can be formed out of silicone, rubber, silicone rubber, or other synthetic and/or natural materials with similar properties. In some embodiments, the resistance of the putty can vary as the user stretches or compresses the putty. In operation, a patient can squeeze the putty in her hand to improve grip and overall hand strength. A patient can also squeeze the putty between her fingers to improve pinch strength and/or to exercise weaker fingers in isolation. A patient can also pull the putty apart using two hands to exercise both hands simultaneously. In some embodiments, the patient can begin physical therapy using the low-resistance putty module 530I and, after gaining strength, the patient can transition to using the high-resistance putty module 530H. The kit 50, the high-resistance putty module 530H, and/or the low-resistance putty module 530I can include instructions for using the putty.
The thimble module 530J includes one or more thimbles for decreasing sensitivity of scars throughout the body and/or for improving fingertip hypersensitivity.
In general, the thimble includes a body 600 having an interior surface 630 and an exterior surface 640. The exterior surface 630 includes features 615 that provide one or more textured regions 610 that a patient can rub against the affected area. The textured regions 610 can have a varying coarseness or roughness. The features 615 can include raised bumps, grooves, or other shapes that have a coarseness appropriate for the skin condition and/or the treatment regimen. The textured regions 610 can have features 615 arranged in various patterns, which can have variations within the pattern such as the distance between each feature and adjacent features, the arrangement of the features (e.g., in linear columns and rows or an offset between adjacent columns and/or rows), and/or the hardness or flexibility of the material that creates the features. These variables, described above, can be the same or different across the textured region 610.
The body 600 has a cavity 620 to receive one or more fingers. A proximal end 650 of the body 600 defines an aperture 655 to allow a finger to penetrate the cavity 620. The interior surface 630 of the distal end 660 of the body 600 is adapted to conform to the tip of one or more fingers. Thus, a patient can mount the apparatus 60 on a finger by inserting the finger(s) through the proximal end 650 of the body 600 and through the cavity 620 to the distal end 660 of the body 600.
The cavity 620 can be cylindrical and can have a central axis 670 extending from the proximal end 650 to the distal end 660 of the body 600. A support member 680 can be disposed on the body 600 to enhance the mechanical strength of the device 60. The support member 680 can be disposed in an orientation orthogonal to the central axis 670.
As discussed above, the thimble device has one or more textured regions 610. For example, a first textured region can have a coarseness appropriate for a first portion of a treatment regimen and a second textured region can have a coarseness appropriate for a second portion of the treatment regimen. The second textured region can have a greater or lower coarseness or roughness than the first textured region. The first and second textured regions can have other variations including the pattern of the features within each textured region, the distance between each feature, the arrangement of the features (e.g., in linear columns and rows or an offset between adjacent columns and/or rows), and/or the hardness or flexibility of the material that creates the features.
In some embodiments, two or more thimbles are included in the thimble module 570J. A first thimble, similar to the thimbles described above, has at least one textured region having a first coarseness appropriate for a first portion of a treatment regimen. A second thimble, also similar to the thimbles described above, has at least one textured region having a second coarseness appropriate for a second portion of the treatment regimen. The thimble module 570J can include additional devices having varying coarseness, which can be used for other portions of the treatment regimen.
Overall, the kit can include contours in its internal walls or working platform structures. For example, outwardly concave contours, hemispherical or similar extrusions can be textured and provide a touching and grasping action for certain therapeutic exercises.
In addition, the thimble module 570J can include a therapeutic cream, which can be used to treat a dermatological condition (e.g., scars, burns, keloids, skin blemishes, incisions, lacerations, abrasions, and/or stretch marks) together or in combination with the thimble described above. The cream can include one, some, or all of the ingredients in Table 1. It is noted that the weight percentages provided in Table 1 are examples and are not intended to be exhaustive. For example, the cream can include plus or minus 1%, 2.5%, 5%, 10%, or 15% of the weight percentage of any ingredient listed in Table 1. The cream can have a pH of about 5.9 (at 25° C.) plus or minus 1%, 2.5%, 5%, 10%, or 15% and it can have a viscosity of about 200,000 cps plus or minus 1%, 2.5%, 5%, 10%, or 15%.
The cream can be infused or stored in a silicone (or similar) elastomer sheet or pad, which can be available in various sizes to use as a dressing over a surgical or traumatic scar. The cream can be located in a recessed compartment within the elastomer sheet or pad. The elastomer sheet or pad can be stored prior to clinical application by using an impermeable or semipermeable peel away covering. For example, the elastomer sheet or pad can be sized and shaped to fit over a caesarian section scar. The sheet or pad can be applied over the entire length of the scar for several weeks following the caesarian section procedure, allowing the scar (and the patient) to benefit from the cream contained in the sheet or pad. Additionally, the sheet or pad can retain moisture, which can soften a scar and protect the skin from post-surgical hypersensitivity.
When used with the thimble, the cream can flow through interstices or channels of the textured regions. For example, the cream can flow through interstices or channels of the first textured region at a first rate and can flow through interstices or channels of the second textured region at a second rate, thereby allowing the cream to flow through the textured regions at the same or different rates.
The kit 50 and/or thimble module 530J can include instructions for using the thimbles.
The dexterity pad module 530K includes different shaped objects and corresponding locations/slots for placing each object. The locations and/or slots are configured to require increasing need for motion, sensibility, strength and/or dexterity, thus training and exercising the patient. In operation, the patient places each object in a corresponding recessed area or slot, which requires fine motor skill, to improve dexterity and function. The development of these skills and strength is generally gradual and utilizes both intrinsic and extrinsic muscles. The kit 50 and/or dexterity pad module 530K can include instructions for using the dexterity pad.
Therefore, a system, which may be provided in the form of a portable kit, is described for therapy to a patient's fingers and/or hand. The system includes a housing, case or enclosure adapted for and having inclusions and extensions supporting the above-described elements and others. In an aspect, the system is integrated into a briefcase-shaped housing. The housing includes an outer shell body (e.g., plastic, wood, metal). The housing has an inner surface and at least one platform or working surface or platform built therein which supports the plurality of therapy modules described. The inner structure of the housing or case includes one or more flat platforms with recessed modules for various types of therapeutic activity. Also, the system folds onto itself and can be portable (e.g., for carrying while travelling). Therefore, with proper instructions a patient can take the system home (or while travelling) and use it to perform therapy exercises without having to come in to a clinic or facility to actively perform the exercises there. This saves time and money for the patient because he or she does not have to travel, park, check in at a clinic and wait for a practitioner to assist them. Assistance can be in the form of written or verbal instructions or other preparation provided to the patient remotely so the system can be used at home. This is especially important for patients without the means to travel or for the elderly or disabled.
When the user's fingers and glove fingers 810 bend inwardly, the rods 820 move with respect to the sensors 800. The movement of the rods 820 causes the sensors 800 to rotate so that the rods 820 continue to extend between adjacent sensors. As the user engages in physical therapy exercises while wearing glove 80, the sensors 800 detect their rotational positions which correspond to the angle of rotation of the respective joints in the user's fingers.
Each glove 80 finger can include a corresponding elastic band 840, and the position or length of each such elastic band 840 can be measured by a respective sensor in wrist band 830. Only one elastic band 840 is illustrated in
A second elastic band 850 is attached to the glove 80 palm and extends from the glove 80 palm to wrist band 830. Elastic band 850 functions in the same way as elastic band 840, but elastic band 850 is used to measure the range of motion of the user's wrist during wrist extension and retraction exercises. A corresponding sensor to measure the position or length of elastic band 840 is disposed in wrist band 830.
The wrist band 830 houses electrical components, such as a microprocessor, a communication interface, and a battery. The microprocessor receives data from the sensors 800 (e.g., via a wired connection) and the sensors for the and transmits the data to an external device over the communication interface. The communication interface can include a wired communication interface and/or a wireless communication interface. The wireless communication interface can include a wireless radio, such as a WiFi radio, a cellular radio, and/or a Bluetooth radio. The wired communication interface can include a USB port, a serial port, and/or an Ethernet port to connect the wrist band 830 to an external device, as kit 860. Kit 860 can be the same as kit 10, kit 20, and/or kit 50. Kit 860 can include a wireless and/or a wired communication interface to further transmit the data, for example to the user's physical therapist and/or to the user's mobile device (e.g., to be accessed by an app on the user's mobile device, as discussed below).
It is noted that although
Sensor 900 can be the same as or different than sensor 800. In addition, rods 910, 920 can be the same as or different than rods 820. Further, glove 930 can be the same as or different than glove 80.
Grip strength can be calculated as well as pinch strength using a pressure transducer within a compressible medium, such as foam, putty, or other similar material. The sensor would function as a dynamometer. This detects changes in force measured in pounds or kilograms. The data received from these sensors would be transmitted to a recording device, either through wireless or wired means. This data is stored and organized using an algorithm that categorizes the information. The algorithm may be encoded in a set of machine stored and machine read program instructions in a memory unit and executed on a processing circuit. This information may then be referred back to or communicated to the physician or therapist, in order to monitor progress and help patients achieve targets or goals.
The radial force sensors 1110 may be disposed about an inner spherical body 1115. This body can likewise by a variation on a spherical shape, e.g., having an oval or elliptical or similar profile. At least a portion of each radial force sensor 1110 can slide inwardly in response to a force along the radius or axis on which the radial force sensor 1110 is aligned. For example, radial force sensor 1112 is disposed parallel to and is generally aligned with axis 1130 which extends radially through inner ball 1115 and compressible ball 1120. Radial force sensor 1112 and axis 1130 can be co-axial, but they are not illustrated as such in
The inward distance that each radial force sensor 1110 slides (e.g., its displacement) is proportional to the force applied along the axis or radius of alignment. For example, radial force sensor 1112 slides inwardly and parallel to axis 1130 when an inward force 1140 is applied at point 1122 on the compressible ball 1120. When the inward force 1140 is released, radial force sensor 1112 returns to its initial state. Thus, the radial force sensors 1110 can sense the direction and magnitude of the force applied to the compressible ball 1100, such as when a user squeezes the compressible ball 1100 to measure a hand's grip strength. The data output of the radial force sensors 1110 can correspond to a map of where a hand's grip strength is relatively high and where a hand's grip strength is relatively low (or zero).
The radial force sensors 1110 are distributed across the outer surface of the inner spherical body 1115 such that the radial force sensors 1110 can sense an inward force from any location on the outer surface of the compressible ball 1120. The number (and density) of radial force sensors 1110 can be increased to provide a higher resolution of a hand's grip strength, and it can be lowered to provide a lower resolution of a hand's grip strength. In some embodiments, the radial force sensors 1110 are push-pin sensors.
The radial force sensors 1110 are in electrical communication with electrical components 1150, including a microprocessor, a communication interface, and a battery. The microprocessor receives data from the radial force sensors 1110 (e.g., via a wired connection) and transmits the data to an external device over a wireless communication interface. The wireless communication interface can include a wireless radio, such as a WiFi radio, a cellular radio, and/or a Bluetooth radio.
In some embodiments, the external computer that receives the data from the pressure sensor ball 1100 can determine the pressure applied by the user's hand. Since pressure is a function of force and area, the external computer would need to determine the area over which the force was applied to determine the pressure. The surface area over which the force was applied, on compressible ball 1120, is proportional to the number of radial force sensors 1110 that sensed a force and the density of the radial force sensors 1110 on the inner spherical body 1115.
Screenshot 1500 illustrates additional feature of the app. For example, screenshot 1500 illustrates a send data button 1520 that allows the user to send some or all of the data collected from the therapeutic apparatus(es) to another party, such as a doctor or a physical therapist. Screenshot also illustrates a sync button 1530 for connecting the user's mobile device 1501 to a given therapeutic apparatus for data collection. The user can switch from syncing the mobile device 1501 with a first therapeutic device to a second therapeutic device using sync button 1530.
The kit 2000 includes a housing 500 having an upper lid 510 and a lower lid 520 as generally described above. Kit 2000 is the same as kit 50 but with the addition of therapeutic tracking glove 80 and pressure sensor ball 1100. In some embodiments, kit 2000 includes therapeutic tracking glove 80 but does not include pressure sensor ball 1100. In other embodiments, kit 2000 includes pressure sensor ball 1100 but does not include therapeutic tracking glove 80. The modules 530 can be removable and/or interchangeable as in kit 50.
Kit 2000 includes optional electronic components as illustrated in
