A therapeutic system and method flexes, extends, and exercises the metacarpal and phalangeal joints of an affected hand. The system comprises a therapeutic glove that receives an affected hand and adjustably applies movement to the fingers and thumb in a first forward direction to form a flexion position, and a second rearward direction to form an extension position. The position of the fingers and thumb as well as the amount of pressure applied is controlled by manipulating restraining members to pull and restrain the fingers and thumb and then attaching to a corresponding body and wrist portion on the glove. The extent of the pulling, including the pressure applied to the metacarpal and phalangeal joints, is fixed, adjustable, and easily releasable. A secondary therapeutic glove compensates for the tactile perception feedback from an unaffected hand. A therapeutic pain relief modality is applied prior to donning the glove.
