Patent ID: 8348810

Claim:
A hand extension/flexion device, comprising: a first anchor element adapted to be positioned adjacent a wrist of a user at a first position; a second anchor element adapted to be positioned about a tip of a finger of the user at a second position, wherein the finger is located between said first anchor element and said second anchor element; a spring member positioned between the first and second anchor elements, said spring member being fixedly secured to said second anchor element and moveable through said first anchor element to thereby allow said spring member to bend about a joint of the finger when said finger is flexed, said first anchor element configured to permit lateral and longitudinal movement of a first, free end of said spring member, said spring member being fixedly secured to said second anchor element at a second end of the spring member so as to statically constrain the second end of the spring member to the top of the finger, said spring member configured to exert bending forces in opposition to working muscles of the user to straighten or flex the joint of the finger; and an intermediary support device disposed between said first anchor element and said second anchor element so as to prevent the spring member from directly contacting the finger joint of the user.
