  • Patent number: 6953440
    Abstract: The apparatus of the present invention stretches the carpal ligament and the flexor retinaculum, as well as the superficial structures and muscles of the hand, in a safe manner under precise control of the patient or a healthcare professional. A first embodiment of the inventive apparatus includes a housing for receiving the patient's hand with pressure elements in contact with the hypothenar, thenar and central longitudinal dorsal portions of the patient's hand. Active pressure sources are provided for the pressure elements and connected to an automatic control unit. The control unit causes the inventive apparatus to delivered therapeutic treatment to the hand by selectively activating the active pressure sources causing the thenar and hypothenar regions of the hand to be pulled apart and upward around the dorsally positioned pressure element in accordance with program instructions indicative of a treatment plan.
