Abstract
An improved exerciser for finger, hand, wrist and forearm is provided with a frame having a hand supporting portion, a first set of pulleys mounted on a frame adjacent the hand supporting portion, and a second second set of pulleys mounted on said frame remote from said hand-supporting portion. A plurality of weight supporting cables are provided having finger-receiving loops at one end and weights attached to the other end. Each of these cables is disposed around a first pulley and a second pulley such that the weights provide resistive force to fingers inserted through the loops when the fingers are flexed. This structure provides an improved apparatus for strengthening the fingers, hand, wrist and forearm, especially following traumatic injury to the hand.
