Embodiments of the present invention are generally related to the manipulation of a joint to provide therapy. More specifically, some embodiments of the present invention use inflatable members and a three point bending concept to cause flexion in a toe joint for the purpose of increasing the range of motion of the toe joint. In one embodiment, a user's foot is placed in a frame with at least one toe atop a toe bar. An inflatable member is positioned atop the user's foot and held in position with a strap attached relative to the frame.
