Abstract
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.
