A six degree of freedom limb movement resistance system is described in which a linkage system of links and joints couples a fixed point in space to a movable end-point of the linkage. A limb coupling cuff is attached to the end point. Variable resistance force can be applied to the linkage via computer controls through a feedback path from position and velocity sensors. The linkage endpoint force acting to resist limb motion is in a direction opposite to the endpoint velocity vector.
