Pronation/supination orthosis and method

摘要

An orthosis for supination and/or pronation of a forearm of a wearer, the orthosis including a base, an upper arm support coupled to the base and configured to secure an upper arm of the wearer, a rotation assembly coupled to the base and including an output member rotatable relative to the base within a rotation plane, and a forearm support member coupled to the output member of the rotation assembly and configured to releasably engage a wrist and the forearm of the wearer, wherein the forearm support member is contoured to receive a thumb of the wearer.

1. A method of stretching viscoelastic body tissue to increase range of motion in supination and/or pronation of a forearm of a person, the method comprising:
coupling an upper arm of the person to an upper arm cuff of an orthosis; coupling a hand, wrist and the forearm of the person to a forearm cuff of the orthosis, comprising:
inserting the hand, wrist and the forearm into the forearm cuff; andtightening first and second straps that are coupled to the forearm cuff at spaced apart locations proximal of the associated radius styloid process and ulna styloid process of the person; and rotating the forearm cuff, after said coupling the wrist and the forearm of the person to the forearm cuff, to supinate or pronate the forearm of the person.
