20160051388 | UPPER EXTREMITY ASSISTANCE DEVICE - An orthotic device includes an upper arm section for receiving an upper portion of an arm of a subject, a forearm section for receiving a forearm section of the arm, and at least one elbow joint rotatably coupling the upper arm section and the forearm section. In the orthotic device, the forearm section includes a release control operatively coupled to the at least one elbow joint, where the release control is configured to transition the at least one elbow joint from a restricted motion state to a free motion state when the release control is activated. | 02-25-2016 |
