ABSTRACT:
The present invention provides a pump assembly which is used to control the amount of extension and flexion of an inflatable pouch which is used to exercise the fingers, hand, or other limb of a patient. A diaphragm pump is provided together with a rotatable cycling valve and a metering control valve to supply air to the diaphragm pump and to cyclically inflate and deflate the pouch upon which a patient's hand is positioned. Manual overrides are provided to inflate and deflate the pouch to a desired degree, dependent upon the position of the hand of the patient as well as the amount of flexion and extension desired and which the patient is capable of. A method of cyclically inflating and deflating the pouch is also provided.
