A therapeutic hand exercise device comprises one or more pliant sleeves 5 for attachment to one or more digits of a human hand, a chamber 4 (figure 2) provided in at least a dorsal region of the or each pliant sleeve 5, a liquid inlet to the chamber and a pump 3 for supplying pressurised liquid to the chamber. Each sleeve is movable between a relaxed state and a stiffened state in which it forms a substantially rigid elongate member for holding the finger disposed within the sleeve in an extended position. A resilient member 6 may be fitted to the palmar side of each pliant sleeve which returns the finger to a state of contracture. The device may be battery powered and may have a control system which controls the length of time the pump is running, it may also record the frequency and duration of operation of the device. The device may be used with a breathable interface liner or a cover which may have bacteriological/sterile filters, and may have a fan to provide airflow over the hand. Energy may be transmitted through the liquid, by heating or cooling, or in the form of vibrations. |
