Shoulder rotation device
View Patent ↗A therapy aid device for improving rotation of shoulder complex is provided. The device includes an upper portion and a lower portion joined together by an angled connector. The upper portion is configured to attach to a user's upper arm and the lower portion is configured to attach to the user's lower arm. The lower portion may also be configured to keep a user's hand in a flexed angled position. Using the device, the user may rotate the shoulder and move while keeping the upper and lower arms and wrist in specific positions. For example, the user may rotate his shoulder such that the user's hand and forearm move away from the torso while the elbow generally remain in the same location.
1. A device for increasing shoulder mobility in a person, consisting of:
an upper portion configured to attach to a person's upper arm;
a lower portion configured to attach to a person's lower arm and open palm such that the open palm and the lower arm are held in a fixed position relative to the upper arm;
a connector joining the upper and lower portions, wherein the connector is positioned at an angle; and
a cylinder fixedly coupled to the connector along a length of the cylinder, the cylinder abutting the connector opposite the upper portion to support continuous manual rotational motion of the device about the cylinder while the length of the cylinder is resting on a planar surface,
wherein the upper and lower portions position the person's upper and lower arms at a fixed angled position that facilitates movement of the shoulder.
2. The device of claim 1 , wherein the upper portion comprises a surface that cradles or otherwise engages the upper arm.
3. The device of claim 2 , wherein the surface is shaped as a trough or a semi-cylinder.
4. The device of claim 1 , wherein the lower portion is configured to isolate the person's hand or wrist in a specific position.
5. The device of claim 1 , wherein the lower portion is configured to keep the person's fingers extended and the person's wrist flexed backward.
6. The device of claim 1 , wherein the lower portion comprises a hand section that engages a person's hand or wrist.
7. The device of claim 6 , wherein the hand section comprises a curved surface that wraps around at least a part of the person's hand.
8. The device of claim 1 , wherein the cylinder is configured to raise a center of gravity of an arm of the person when the person is in a supine position.
9. The device of claim 1 , wherein a longitudinal axis of the cylinder is aligned with a portion of the connector to which the upper portion is connected.
10. The device of claim 1 , further comprising one or more straps configured to encircle at least part of an arm or a hand of the person.
11. The device of claim 10 , wherein the one or more straps are disposed on the upper portion or the lower portion.
12. The device of claim 1 , wherein the connector comprises a bend that is 90°.
13. The device of claim 1 , wherein a position of the lower portion on the connector is adjustable.
14. The device of claim 12 , wherein the connector has a first location spaced apart from a second location, each of the first and second locations being configured for attachment with the lower portion, the lower portion being positioned further away from the cylinder when the lower portion is attached to the first location than when the lower portion is attached to the second location.
