A hand splint for exercising the fingers of the hand which splint includes a base for supporting the hand, and a plurality of elements each secured to corresponding fingers and operatively connected with a power source that repetitively shifts the elements in order to exercise the fingers. Power transmitting means, in the form of flexible cords extending from the power source to each of the elements, are coupled to the base in such a manner as to shift the elements along a preselected path between protracted and retracted positions to thereby shift the fingers in a natural motion between an extended position and a position naturally folded toward the palm of the hand.
