  • Patent number: 7874996
    Abstract: 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. As the inflatable member is inflated, the strap increases in tension urging the toe toward the toe bar and causing actuation of the joint at the base of the toe.

  • Patent number: 6872186
    Abstract: An orthotic apparatus for use in providing improved range of motion is provided which allows the amount of stretch to be hydraulically powered and measured by the device, but controlled by the user. Because the apparatus accurately calculates the amount of stretch, the user, together with the user's physician and therapist, can develop a rehabilitation plan based on accurate measurements. Progress is based on tangible results rather than the user's ability to tolerate pain. This knowledge provides the incentive the user needs to work toward and achieve the user's goal.
