A movement device for flexing and/or straightening a joint of a user includes a first anchor element adapted to be positioned adjacent a jointed appendage of a user at a first position. A second anchor element is adapted to be positioned about the jointed appendage at a second position, wherein the jointed appendage is located between the first anchor element and the second anchor element. A spring member is positioned between the first and second anchor elements wherein the spring member is fixedly secured to the second anchor element and moveable through the first anchor element to thereby allow the spring member to bend about a joint of the appendage when said appendage is flexed. The spring member is configured to exert bending forces in opposition to working muscles of the user to straighten or flex the joint of the appendage. To minimize discomfort, an intermediary support device is disposed between the first anchor element and the second anchor element which prevents the spring member from contacting the joint of the user.

Low profile hand-extension/flexion device

A hand movement device comprises a glove for positioning about a hand of a user, a first anchor element adapted to be positioned about a base surface of glove, a second anchor element adapted to be positioned at a tip of a finger portion of the glove, an active spring member positioned between the first and second anchor elements, said active spring member being fixedly secured to said first anchor element and moveable through said second anchor element to thereby allow said spring member to bend about a joint of the finger when said finger is flexed, an activating element positioned adjacent the active spring member to heat or cool said active spring member thereby causing the spring member to bend or straighten, and an intermediary support device for housing said spring element and for connecting the first anchor element to said second anchor element.
