Abstract
A portable controllable fluid device (20a) for rehabilitation of injured limbs, appendages and joints (33a). The rehabilitation device (20a) includes a first bracket (22a) for fixedly securing to a first body part, such as a lower leg (25), a second bracket (24a) for fixedly securing to a second body part, such as a foot (26), and a controllable fluid brake (27a) such as a magnetorheological fluid brake including a magnetorheological fluid contained therein having a carrier fluid and disbursed magnetic particles, attached between the first bracket (22a) and second bracket (24a). The controllable fluid brake (27a), preferably acts in a rotary fashion and provides resistive forces about an axis adjacent said body joint (33a) to exercise the muscles upon movement of said first bracket (22a) relative to said second bracket (24a) resulting from movement of the user's first body part relative to the second body part. The device (20a) is portable and can be used to rehabilitate, for example, a wrist, elbow, knee or ankle joint in the user's home. The device (20a) allows variable adjustment of the level of resistance felt by the rehabilitating user by adjusting a controller (28a). In anoth…
