CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims priority to US Provisional Application No. 62/393,348 filed September 12, 2016, entitled ADJUSTABLE REHABILITATION AND EXERCISE DEVICE, incorporated herein by reference in its entirety.

FIELD

[0002] This disclosure relates to the field of rehabilitation devices. More particularly, this disclosure relates to adjustable rehabilitation devices having improved connection and adjustability of patient engagement members, and rehabilitation devices capable of providing continuous passive motion for improved rehabilitation options.

BACKGROUND

[0003] Improvement is desired in the construction of adjustable rehabilitation and exercise devices. Adjustable rehabilitation and exercise devices having pedals on opposite sides and adjustably positionable relative to one another have been proposed. However, such designs require improvement due to the fact that the pedals tend to not remain securely mounted and detach, wobble and the like. In addition, it is desirable to provide for an adjustable rehabilitation or exercise device that is capable of providing both powered motion or user initiated motion without the need for separate devices.

[0004] Accordingly, in one aspect, the disclosure provides an adjustable rehabilitation and exercise device having patient engagement members on opposite sides of a rotary member. The patient engagement members are adjustably positionable radially and angularly.

[0005] Improvement is desired in the construction of rehabilitation and exercise devices. Conventionally, rehabilitation and exercise devices are either powered solely by the patient by muscle force of the patient, or are solely powered by a powered motive force such as supplied by an electric motor for provision of continuous passive motion ("CPM").

[0006] The powered devices simply rotate pedals to which the feet of the patient are secured and the patient is a passive participant or are a CPM device of known construction and configuration. The powered devices serve to move the feet/legs of the patient through a range of motion, but do not permit or require any application of muscle force by the patient. These devices are typically utilized in early stages of rehabilitation just to impart motion to the legs or as CPM treatment is otherwise indicated by the patient's condition, diagnosis or treatment/rehabilitation plan. Once the patient is better able to exert muscle force, a conventional muscle powered device with variable resistance is utilized. Alternatively, a home medical company, durable medical equipment company or mobile rehabilitation company may have the need to treat multiple patients requiring different treatment or rehabilitation protocols. In some instances, certain patients may have been prescribed CPM protocols while other patients have been prescribed patient muscle powered treatment protocols and it would be useful to be able to provide both types of protocols with a single device. [0007] Presently, no known device exists that provides continuous passive motion, powered or powered movement assistance and yet enables participation by the patient in application of muscle force in a manner in which the motor used in the CPM or powered mode is selectively engageable. Such a device is desired and provided by the present disclosure.

DETAILED DESCRIPTION

[0039] With initial reference to FIGS. 1A-1B, there is shown an adjustable rehabilitation and exercise device 10 having patient engagement members, such as pedals 12 on opposite sides that are adjustably positionable relative to one another, but securely mounted according to the disclosure to provide a more secure mounting that avoids disconnection, wobbling and the like often experienced with prior devices.

[0040] The device 10 includes a rotary device such as a wheel 14 or flywheel or the like rotatably mounted such as by a hub to a frame 16 or other support. The pedal 12 is configured for interacting with a patient to be rehabilitated and may be configured for use with lower body extremities such as the feet, legs, or upper body extremities such as the hands, arms, and the like. For example, the pedal 12 may be a conventional bicycle pedal of the type having a foot support rotatably mounted onto an axle with bearings. The axle has exposed end threads for engaging a mount on the wheel 14 to locate the pedal on the wheel 14.

[0041] The wheel 14 may be configured to have both pedals 12 on opposite sides of a single wheel. However, a preferred construction, as seen in FIGS. 1A and IB shows a pair of the wheels 14 spaced apart from one another but interconnected to a flywheel or the like.

[0042] The rehabilitation and exercise device 10 of FIGS. 1A-1B may take the form as depicted of a traditional exercise/rehabilitation device which is more or less non-portable and remains in a fixed location, such as a rehabilitation clinic or medical practice.

[0043] Alternatively, the device 10 may be configured to be smaller and more portable unit so that it is able to be easily transported to different locations at which rehabilitation or treatment is to be provided, such as a plurality of patient's homes, alternative care facilities or the like.

[0044] A significant aspect of the disclosure relates to the structures described herein that enable and facilitate relative adjustment of a pair of patient engagement members. The disclosure provides show various configurations for wheel structures according to the disclosure to advantageously enable the patient engagement members, such as pedals, to be radially and angularly adjustable relative to one another on opposite sides of an exercise device, such as the device 10.

[0045] The drawings sets herein show alternate embodiments of systems that enable and facilitate relative adjustment of a pair of patient engagement members and that are suitable for use with exercise and rehabilitations devices, such as the device 10

[0046] With reference to FIGS. 2A-2D, there is shown a wheel system 20 having a patient engagement member, such as a pedal 22 adjustably mounted on a wheel 24 by an adjustable mount 26. It will be appreciated that the patient engagement member may be configured to engage a hand or foot or other member of a patient as may be desired for rehabilitation. The pedal 22 may be a conventional pedal and includes a support rotatably mounted on an axle 22a. The axle 22a has exposed threads for being received by a corresponding threaded aperture of the mount 26. It will be appreciated that a pair of the wheels 24 may be utilized or, alternatively, a single one of the wheels 24 with a mount and pedal on each side.

[0047] The wheel 24 is a disk configured to include a plurality of spaced apart elongated slots 24a that extend through the thickness of the wheel 24. The slots 24a include a plurality of uniformly spaced teeth or cogs 24b along both sides of the length of the slots 24a. Raised ribs 24c are located on opposite sides of a rear surface of the slots 24a for cooperating with the mount 26.

[0048] The wheel 24 also includes a hub or central mounting aperture 24d for rotatably mounting of the wheel 24, such as to the device 10. Material of the wheel 24 may be removed to provide openings 24e to provide aesthetics and for reducing the weight and the cost of the wheel 24.

[0049] The mount 26 is I-shaped and includes a front plate 26a and a rear plate 26b connected by a center portion 26c. The axle 22a connects to a receiver 26d of the front plate 26a. A spring 26e is located on the rear plate 26b to urge a pin 26f toward the front plate 26a. The pin 26f extends between the spring 26e and the front plate 26a, with a tip of the pin 26f extending through an aperture 26g of the front plate 26a. The pin 26f has an enlarged head 26h that rests against the spring 26e and seats in the cogs 24b of the slot 24 to lock the position of the mount 26 relative to the slot 24.

[0050] The mount 26 is configured to stably locate the pedal 22 or other patient engagement member and eliminate wobble and the like associated with conventional devices. In addition, the mount 26 is also configured to advantageously enable substantially incremental adjustment of the position of the mount 26. The pin 26f and the spring 26e cooperate with the slot 24a to provide a lock for the mount 26 to lock the position of the mount 26 relative to the slot 24a. By a user pressing on the tip of the pin 26f, which thus serves in the manner of a push button, the pressure of the spring may be overcome to disengage the head of the pin 26f from the cogs 24b and enable the mount 26 to be moved relative to the slot 24b. In this manner, the location of the mount 26 may be incrementally adjusted along the slot 24.

[0051] Accordingly, it will be appreciated that the mount 26 cooperates with the slot 24a to adjustably position the mount 26, and hence the pedal 22, relative to the wheel 24. Further, the availability of a plurality of slots 24a enables a user to select which slot 24a for installation of the mount. Thus, in combination, the mount 26 and the slots 24a enable radial and angular adjustment of the position of the pedal 22. When this manner of adjustment is used for both of the pedals 22 on opposite sides of the device 10, it will be appreciated that the pedals 22, or other patient engagement members, may be adjustably positioned relative to one another angularly, with each pedal being radially adjustable relative to the hubs of the wheels.

[0052] With reference to FIGS. 3A-3E, there is shown a wheel system 30 having a patient engagement member, such as a pedal 32 adjustably mounted on a wheel 34 by an adjustable mount 36.

[0053] The wheel 34 is a disk configured to include a plurality of spaced apart elongated slots 34a that extend through the thickness of the wheel 34. The slots 34a include a plurality of uniformly spaced arcs 34b along both sides of the length of the slots 34a. Raised ribs 34c are located on opposite sides of a rear surface of the slots 34a for cooperating with the mount 36. [0054] The wheel 34 also includes a hub or central mounting aperture 34d for rotatably mounting of the wheel 34 to the device 10 or the like. Material of the wheel 34 may be removed to provide openings 34e to provide aesthetics and for reducing the weight and the cost of the wheel 34.

[0055] The mount 36 includes a front plate 36a and a rear plate 36b connected by a fastener 36c that extends though the slot 34a. The axle 32a connects to a receiver 36d of the front plate 36a. A spring 36e is located on the rear plate 36b by the fastener 36c and is located to urge a pin 36f toward the front plate 36a. The pin 36f extends between the spring 36e and the front plate 36a, with a tip of the pin 36f extending through an aperture 36g of the front plate 36a. The pin 36f has an enlarged head that rests against the spring 36e and seats in the arcs 34b of the slot 34 to lock the position of the mount 36 relative to the slot 34.

[0056] The mount 36 is configured to stably locate the pedal 32 or other patient engagement member and eliminate wobble and the like associated with conventional devices. The mount 36 also enables substantially incremental adjustment of the position of the mount. The pin 36f and the spring 36e cooperate with the slot 34a to provide a lock for the mount 36 to lock the position of the mount 36 relative to the slot 34a. By a user pressing on the tip of the pin 36f, which thus serves in the manner of a push button, the pressure of the spring may be overcome to disengage the head of the pin 36f from the arcs 34b and enable the mount 36 to be moved relative to the slot 34b. In this manner, the location of the mount 36 may be incrementally adjusted along the slot 34.

[0057] The mount 36 cooperates with the slot 34a to adjustably position the mount 36, and hence the pedal 32, relative to the wheel 34. Further, the availability of a plurality of slots 34a enables a user to select which slot 34a for installation of the mount. Thus, in combination, the mount 36 and the slots 34a enable radial and angular adjustment of the position of the pedal 32. When this manner of adjustment is used for both of the pedals 32 on opposite sides of the device 10, it will be appreciated that the pedals 32, or other patient engagement members, may be adjustably positioned relative to one another angularly, with each pedal being radially adjustable relative to the hubs of the wheels. [0058] With reference to FIGS. 4A-4E, there is shown a wheel system 40 configured to have a patient engagement member, such as a pedal adjustably mounted on a wheel 44 by an adjustable mount 46.

[0059] The wheel 44 is a disk configured to include a plurality of spaced apart elongated slots 44a that extend through the thickness of the wheel 44. The slots 44a include a plurality of uniformly spaced arcs 44b along both sides of the length of the slots 44a. Channels 44c extend through the wheel 44 adjacent the slots 44a for cooperating with the mount 46. For simplicity, only some of the channels 44c are shown in some of the views, it being understood that a set of the channels 44c will be provided in the same manner for each of the slots 44a.

[0060] The wheel 44 may also include a hub or central mounting aperture for rotatably mounting of the wheel 44, such as to the device 10. Material of the wheel 44 may be removed to provide openings 44e to provide aesthetics and for reducing the weight and the cost of the wheel 44.

[0061] The mount 46 includes a front plate 46a and a rear plate 46b connected by a fastener 46c that extends though the slot 44a. An axle of the patient engagement member connects to a receiver 46d of the front plate 46a. A spring 46e is located on the rear plate 46b by the fastener 46c and is located to urge a pin 46f toward the front plate 46a. The pin 46f extends between the spring 46e and the front plate 46a, with a tip of the pin 46f extending through an aperture 46g of the front plate 46a. The pin 46f has an enlarged head 46h that rests against the spring 46e and seats in the arcs 44b of the slot 44 to lock the position of the mount 46 relative to the slot 44. Pegs 46i are located to extend through the channels 44c and between the front plate 46a and the rear plate 46b, and ride within sleeves 46j.

[0062] The mount 46 is configured to stably locate a pedal or other patient engagement member and eliminate wobble and the like associated with conventional devices. The mount 46 also enables substantially incremental adjustment of the position of the mount. The pin 46f and the spring 46e cooperate with the slot 44a to provide a lock for the mount 46 to lock the position of the mount 46 relative to the slot 44a. By a user pressing on the tip of the pin 46f, which thus serves in the manner of a push button, the pressure of the spring may be overcome to disengage the head of the pin 46f from the arcs 44b and enable the mount 46 to be moved relative to the slot 44b. In this manner, the location of the mount 46 may be incrementally adjusted along the slot 44.

[0063] The mount 46 cooperates with the slot 44a to adjustably position the mount 46, and hence the pedal, relative to the wheel 44. Further, the availability of a plurality of slots 44a enables a user to select which slot 44a for installation of the mount. Thus, in combination, the mount 46 and the slots 44a enable radial and angular adjustment of the position of the pedal. When this manner of adjustment is used for both of the pedals on opposite sides of the device 10, it will be appreciated that the pedals, or other patient engagement members, may be adjustably positioned relative to one another angularly, with each pedal being radially adjustable relative to the hubs of the wheels.

[0064] With reference to FIGS. 5A-5D, there is shown a wheel system 50 having a patient engagement member, such as a pedal 52 adjustably mounted on a wheel 54 by an adjustable mount 56.

[0065] The pedal 52 may be a conventional pedal and includes a support rotatably mounted on an axle 52a. The axle 52a has exposed threads for being received by a corresponding threaded aperture of the mount 56

[0066] The wheel 54 is a disk configured to include a plurality of spaced apart apertures 54a that extend through the thickness of the wheel 54. The wheel 54 may also include a hub or central mounting aperture 54d for rotatable mounting of the wheel 54.

[0067] The mount 56 includes a plate 57 and an arm 58. The plate 57 includes a central wheel aperture 57a aligned with the central mounting aperture 54d of the wheel 54. A fastener 57b passes through the wheel aperture 57a and the central mounting aperture 54d for connecting the plate 57 to the wheel 54, and for connecting the wheel 54 to an exercise device. A plate adjustment aperture 57c is located to selectively align with the apertures 54a of the wheel 54. A spring-loaded pin 57d is provided to selectively pass through the plate adjustment aperture 57c and one of the apertures 54a to adjust the angle of the plate 57 relative to the wheel 54. The plate 57 also includes an elongated curved slot 57e, arm lock apertures 57f, and an arm receiver 57g.

[0068] The arm 58 includes a pivot mount 58a, a lock aperture 58b, lock pin 58c, receiver 58d, and a guide 58e. The pivot mount 58a may be provided as by an aperture that aligns with the arm receiver 57g of the plate 57, with a fastener or the like extending therethrough to pivotally connect the arm 58 to the plate 57. The receiver 58d is threaded to receive the threads of the axle 52a of the pedal 52 or other patient engagement member.

[0069] The mount 56 is configured to stably locate a pedal or other patient engagement member and eliminate wobble and the like associated with conventional devices. In addition, the mount 56 is also configured to advantageously enable substantially incremental adjustment of the position of the mount. The pin 57d cooperates with the apertures 54a to adjust and fix the position of the arm 57 relative to the wheel 54. Further, angle of the arm 58 relative to the plate 57 may be adjusted and fixed by use of the lock pin 58c and the arm lock apertures 57f. Thus, in combination, the adjustment of the plate 57 relative to the wheel 54 and the adjustment of the arm 58 relative to the plate 57 enables radial and angular adjustment of the position of the pedal 52. When this manner of adjustment is used for both of the pedals on opposite sides of the device 10, it will be appreciated that the pedals, or other patient engagement members, may be adjustably positioned relative to one another angularly, with each pedal being radially adjustable relative to the hubs of the wheels.

[0070] With reference to FIGS. 6A-6C, there is shown a wheel system 60 having a patient engagement member, such as a pedal 62 adjustably mounted on a wheel 64 by an adjustable mount 66.

[0071] The pedal 62 may be a conventional pedal and includes a support rotatably mounted on an axle 62a. The axle 62a has exposed threads for being received by a corresponding threaded aperture of the mount 56 [0072] The wheel 64 is a disk configured to include a plurality of spaced apart apertures 64a that extend through the thickness of the wheel 64. The wheel 64 may also include a hub or central mounting aperture 64d for rotatable mounting of the wheel 64.

When the lever 86e is depressed, the pin 86f extends between the gap between the rear plate 86b and the front plate 86a, and passes through one of the notches 84a to lock the position of the mount 86. The lever 86e may be reversed to retract the pin 86f to permit the location of the mount 86 to be adjusted.

[0085] The mount 86 is configured to stably locate a pedal or other patient engagement member and eliminate wobble and the like associated with conventional devices. The mount 86 also enables substantially incremental adjustment of the position of the mount, and hence a patient engagement member, relative to a wheel. Further, the availability of a plurality of supports 84 on a wheel enables a user to select which support 84 for installation of the mount 86. Thus, the system 80 enables radial and angular adjustment of the position of a patient engagement member. When this manner of adjustment is used for locating patient engagement members on opposite sides of the device 10, it will be appreciated that the patient engagement members, may be adjustably positioned relative to one another angularly, with each pedal being radially adjustable relative to the hubs of the wheels.

A receiver 96d is located on the mount 96 for mounting a patient engagement member, such as a pedal. For example, axle 92a of the pedal is screwed into the receiver 96d.

[0089] The mount 96 is configured to stably locate a pedal or other patient engagement member and eliminate wobble and the like associated with conventional devices. The mount 96 enables substantially incremental adjustment of the position of the mount, and hence a patient engagement member, relative to a wheel. Further, the availability of a plurality of supports 94a on a wheel enables a user to select which support 94a for installation of the mount 96. Thus, the system 90 enables radial and angular adjustment of the position of a patient engagement member. When this manner of adjustment is used for locating patient engagement members on opposite sides of the device 10, it will be appreciated that the patient engagement members, may be adjustably positioned relative to one another angularly, with each pedal being radially adjustable relative to the hubs of the wheels.

[0090] With reference to FIGS. 10A-10G, there is shown a wheel system 120 having a patient engagement member, such as a pedal 122 adjustably mounted on a wheel 124 by an adjustable mount 126.

[00106] FIG. l lC shows the plunger 226e released, as by pulling upward on the handle 226f. The tower 226c may then be lifted to move the slide member 226a and position it so the legs 226d are seated on a pair of the pegs 224c corresponding to a different radial location. Once the mount 226 is relocated with the legs 226d seated onto a different pair of the pegs 224c at a desired position, the handle 226f is released to reapply the plunger 226e and securely locate the mount 226 at the new radial location on the wheel 224.

[00107] The mount 226 is configured to stably locate a pedal or other patient engagement member and eliminate wobble and the like associated with conventional devices. In addition, the mount 226 is also configured to advantageously enable substantially incremental adjustment of the position of the mount.

[00108] The mount 226 cooperates with the track 224a to adjustably position the mount 226, and hence the pedal, relative to the hub on which the wheel 224 rotates. Further, the availability of a plurality of tracks 224a enables a user to select which track 224a for installation of the mount 226. Thus, in combination, the mount 226 and the tracks 224a enable radial and angular adjustment of the position of the pedal or other patient engagement member. When this manner of adjustment is used for both of the pedals on opposite sides of the device 10, it will be appreciated that the pedals, or other patient engagement members, may each be adjustably positioned radially relative to the hub on which the wheels rotate, and angularly relative to one another.

[00109] With reference to FIGS. 12A-12E, there is shown a wheel system 320 having a patient engagement member, such as a pedal adjustably mountable on a wheel 324 by an adjustable mount 326.

It will be appreciated that the wheel 514 will include patient engagement members, such as a pedal 514a. Preferably, one of the wheels 514 with a pedal is mounted on either side of the frame 516.

[00132] The pedal 514a is desirably adjustably positionable on the wheel 514. As shown, the wheel 514 includes a plurality of spaced apart and elongated slots 514b, with a mount adjustably connecting the pedal 514a to one of the slots so that the pedal location is radially adjustable to hub or the center where the wheel is mounted. Thus, the ability to select amongst the slots 514b and the radial location along the slot 514b for the pedals 514a on the wheels 514 on either side of the device 500, a user may adjust the location of the pedals 514a relative to the hub and angularly with respect to one another.

[00133] The motor 512 is connected to the wheel 514 as by a clutch 518, such as a slip differential clutch. The clutch 518 may be electronically or manually linked to the motor 512 as by a linkage 520. The motor 512 is configured to desirably rotate the wheel 514 so that the device 500 may serve to move the feet/legs of the patient through a range of motion, but do not require any application of muscle force by the patient. If desired, the clutch 518 may be operated to disconnect the motor 512 from the wheel 514 so that the only force applied to the wheel 514 will be the muscle force of the patient.

[00134] The clutch 518 is also advantageously operable to provide continuous passive motion and enable powered movement of a desired and adjustable amount provided by the motor 512, yet enable desired participation by the patient in application of muscle force. When the clutch 518 is disengaged it is desirable for adjustable resistance to be applied to resist the muscle powered rotation of the patient engagement members in a conventional fashion to facilitate the smooth rotation of the patient engagement members and/or to facilitate exercise of the patient's extremities.

[00135] The motor and the clutch are operable to:(l) apply the force output of the motor to rotate the rotary member at a first motor rotational rate without application of any muscle force by a patient, (2) not apply the force output of the motor to the rotary member so that muscle force must be applied by the patient to rotate the rotary member at a first patient rotational rate, or (3) apply the force output of the motor to the rotary member in a varying amount, to provide the output force of the motor in amount to provide a second motor rotational rate to provide continuous passive rotational motion of the rotary member, yet enable desired participation by the patient to apply muscle force to rotate the rotary member.

[00136] When the patient applies muscle force, the motor and the clutch may be operated to (a) maintain the rate of rotation the rotary member the same as when the patient is not applying muscle force, with the amount the force output of the motor being decreased in an amount corresponding to the amount of muscle force applied by the patient, or enable the rate of rotation of the rotary member to increase corresponding to the amount of muscle force applied by the patient.

[00137] In addition, the device 50 may be operated to apply rotational force from the motor to the rotary member when in a patient selected continuous passive motion (CPM) mode without requiring use of muscle power; freewheel when in a patient selected freewheel mode so that the motor is completely disengaged from the rotary member; or apply rotational resistance from the motor to the wheel when in a patient selected exercise mode to resist muscle powered rotation of the wheel with the amount of resistance being selectable by the patient, such that the motor functions in the nature of a generator.

[00138] Accordingly, it will be appreciated that devices according to the disclosure are configured to provide continuous passive motion, powered or powered movement assistance, yet enable participation by the patient in application of muscle force in a manner in which the motor used in the CPM or powered mode is selectively engageable.

[00139] With reference now to FIG. IB, there is shown a variation of the device 500, which further includes a computer processor 522 in electrical communication with both the motor and a plurality of patient sensors 524. The computer processor 522 is able to wirelessly receive signals from the sensors 524, and is programmable to enable desired actions to be taken in response to the signals received from the sensors 524. For example, one of the sensors 524 is shown on the knee of the patient. This sensor may be a range of motion sensor. Another sensor is shown on the chest area. This may be a heart rate sensor. Another sensor is shown on the foot of the user. This may be a blood flow or oxygen sensor. As will be appreciated, a number of different sensors may be utilized. The computer processor 522 may be programmed to sound alarms, increase or decrease the force output of the motor, and the like based on the combination of inputs from the sensors. It will be further appreciated that data associated with the output of the sensors 524 may be stored and utilized in monitoring the patient and collecting data about the patient and the exercise and rehabilitation of the patient.

[00140] For example, data such as pedal revolutions, time of use, pedaling speed, and any other data from other sensors may be tracked via the computer processor and transmitted wirelessly to a data server from which they are uploaded to the patient's medical records. The data can also be pushed to the patient's smartphone where a mobile application tracks and displays the patient's activity, including a graph of usage and progress over time.

[00141] These data collection features offer three significant advantages over current CPM units. For example, a physician and/or physical therapist can monitor their patient's use remotely, ensuring the patient is using the device for the duration and frequency directed. The physician or therapist can also be notified in the event a patient is failing to use the device, and contact the patient to follow up via a billable telemedicine video or phone call.

[00142] Also, this device enables for the first time, detailed data regarding post-operative therapeutic exercise at home can be collected by both healthcare providers and payors, and correlated with patient outcomes, speed of recovery, and reduction of complications and re-admissions. These features also present a significant value to insurers, to whom specific patient data is particularly valuable.

[00143] The sensors 524 may also be configured to be electrodes for electrical muscle stimulation to push electrical current into the muscle tissue below, resulting in a sensory or motor response. For this use, wires may be connected to each electrode to supply electrical current from a controllable source of electrical power. Alternatively, as represented by the dashed lines, a wireless connection may be made to each electrode, with a source of electrical power controlled by the computer processor. Electrical stimulation supplied by the electrodes are utilized for pain relief and muscle re-education, in which the electrical current helps the atrophied muscle(s) contract. Along with increasing muscle function, the contraction of the muscle promotes blood flow to the area that assists in healing. [00144] With reference to FIG. 15C, there is shown a device configured in the manner of the device 500, except of reduced weight and dimension and configured for placement on a table or bed or the like. As shown, the device is configured to exercise the upper body of the patient.

[00145] With reference to FIG. 15D, there is shown a device configured in the manner of the device 500, except it is adapted to be mountable adjacent a hospital bed or the like. For example, in this case, the device is adjustably mounted on mount, such as a ceiling track, and may be raised or lowered or moved laterally or longitudinally or otherwise adjusted in position relative to the patient, as depicted by the double-ended arrows. As will be appreciated, this enables the device to be conveniently adjusted in position to the patient, and moved away from the bed or other location when not in use. It will be appreciated that instead of locating the device on a ceiling track, a track or the like may be mounted on the bed or other desired location.
