DETAILED DESCRIPTION OF THE INVENTION

(11) Disclosed herein is a device for shoulder rehabilitation. Also described are methods for using the same. The shoulder rehabilitation device described herein is configurable for a variety of movements to exercise, stretch, and strengthen the shoulder. The device is also configurable to fit a variety of patients, from athletes to the wheelchair bound and from young to the elderly.

(12) FIG. 1 illustrates one embodiment of a shoulder rehabilitation device. FIG. 1A shows platform 100 coupled to support leg 114 and optionally in contact with support legs 116 or 118. Platform 100 provides a stable, rigid base for guide rails 110a or 110b. In certain aspects a device will comprise guide rail 110a and a smaller more limited motion guide rail 110b. Some embodiments will comprise a single guide rail, represented by guide rail 110a or 110b. A guide rail can be shaped to guide a patient's hand along a predetermined path to achieve any number of motions. In certain aspects the guide rail is an arc to facilitate a rising rotating motion of the shoulder. In other aspects the guide rails can be in an oval arc, circular arc or undulating shape. Guide rails can be bent solid cylinders or tubes having a diameter of about 0.25, 0.5, 1.0, 1.25, 1.5, or 2.0 inches, including all values and ranges there between. In certain aspects the guide rail can be tapered or have a varying diameter to provide variable resistant. The guide rail can have a certain diameter at the ends of guide rail with the diameter gradually getting smaller as you progress to the midpoint. In other aspect the guide rails can have the smallest diameter at the guide rail ends with the diameter gradually increasing to a maximum at the midpoint of the rail. Other variations diameter are contemplated and can include a number of cycles larger to small diameter along the length of the guide rail. The guide rail ends can be positioned about 0.5, 1, 1.5, 2, 2.5, or 3 feet apart, including all values and ranges there between. The guide rail can be 1, 1.5, 2, 2.5, 3, or 3.5 feet in height, including all values and ranges there between. The guide rails can be maid of any suitable such as metal or polymer.

(13) In certain aspects supports 114, 116, and 118 can be height adjustable and capable of being locked in place, e.g., by a pin. Platform 100 can be coupled to support 114 by joint 101. Joint 101 can rotate about the z axis as a hinge, rotate about the x axis, or be configured to rotate about the z and x axis to provide for changing the orientation of guide rail 110a and/or 110b, e.g., from an upward position to a downward (flipping), which in turn alters guide rail 110 and the path and resulting shoulder motion of a patient moving hand grips 112 along guide rail 110. FIG. 8 illustrates a joint having multiple degrees of freedom and can rotate about the x and/or z axis. The embodiment of FIG. 1B depicts joint 101 that is configured to rotate platform 100 around a horizontal or x axis. The rotation can be to any degree and the platform locked at any point along the circumference of rotation. In certain aspects the device can be locked by a clamp or friction mechanism. The clamping or friction mechanism can be adjusted by tightening or loosening a screw mechanism. FIG. 1C is an illustration of an overhead view that shows an associated padded support 120 for resting a patient's elbow or other body part during while using the device.

(14) Hand grip 112 is designed to be grasped by a patient and to move along guide rail 110 (in certain aspects the hand grip forms a lumen in which the guide rail is positioned) under force applied by a patient (as depicted in FIG. 2 by a guide rail 210 and a passive hand grip 212) or in certain aspects a mechanical assist can be provided using a cable or gear attached to hand grip 112 (FIG. 3 shows one embodiment that can be used to provide resistance or assistance). In FIG. 3 the gear 322 can be coupled to a resistance mechanism or to a motor or crank to provide assistance during movement of hand grip 312. In a further aspect, as depicted in FIG. 9A, an assist cable 324 can be positioned along the long axis of guide rail 310 with one end attached to hand grip 312 and the other end attached to a pulling mechanism, e.g., an electric motor or a hand crank 326. In certain aspects a two-way assist can be provided by attaching a first cable to assist in a first direction and a second cable to assist in a second direction. FIG. 3 illustrates a geared hand grip that can also be passive or it can be coupled to a resistance mechanism that requires some force to move the hand grip along the guide rail. In other aspects resistance can be adjusted by adding weight to hand grip 112 or providing hand grips of different weight to be attached to the device. In certain aspects the resistance can be adjusted for the needs of particular patients.

(15) FIG. 4 illustrates another embodiment of the hand grip. FIG. 4 shows grip 412 having a friction sleeve 460 that can be adjusted by expanding or narrowing notch 431. When the notch is narrowed friction sleeve 460 provides greater resistance due to friction between friction sleeve 460 and guide rail 410. In certain aspects a notch 431 can be provided in friction sleeve 460. Notch 431 and receive tab 432, which guides handgrip 412.

(16) FIG. 5 illustrates a pole-mounted embodiment of the device. The pole-mounted device comprises guide rails 569 and 570 coupled to support collars 571 and 572. Either one or both poles can be stably mounted. Stably mounted refers to securing the pole such that swaying and other movement is limited and allows one to use the device without unnecessary movement. In certain aspects the support collars can comprise rotatable attachments 580 for guide rail 510. Rotatable attachments 580 allow the guide rail to be rotated around the horizontal axis between support collars 571 and 572. The rotatable attachments can lock in position, thus the guide rail can be positioned at any point along the circumferential rotation or at any particular height. FIG. 6 shows device of FIG. 5 with guide rail in an inverted position.

(17) One benefit of such a device is that the device can be configured to target the rotator cuff. Most other devices only target the posterior and interior portion of the shoulder while this device targets those areas as well as the rotator cuff. Furthermore, the current device can be configured a number of ways specifically target various motions or accommodate all types of people. FIG. 7 illustrates a configuration for a wheelchair bound individual. The devices described herein use guided motion to target particular joints, muscles, and tendons. Such devices can be used as a warm up to help prevent shoulder injuries, to strength train and rehabilitate the shoulder, and to increase the flexibility of the shoulder.

(18) The disclosed device and method of use is generally described, with examples incorporated as particular embodiments of the invention and to demonstrate the practice and advantages thereof It is understood that the examples are given by way of illustration and are not intended to limit the specification or the claims in any manner.
