Abstract
A passive exercise apparatus includes an interface member for coupling to a user's limb. An arm member is coupled to the interface member by a wrist joint. The wrist joint has rotational motion about three axes. A first link is coupled to the arm member by a sliding joint. The sliding joint allows translational motion of the arm member relative to the first link. A second link is rotatably coupled to the first link by a first rotary joint. A third link is rotatably coupled to the second link by a second rotary joint. A first brake is coupled to the first rotary joint for resisting movement of the first rotary joint. A second brake is coupled to the second rotary joint for resisting movement of the second rotary joint. A third brake is coupled to the arm member for resisting movement of the arm member. The user is capable of interfacing with the apparatus to exercise a six degree of freedom motion.
