A passive therapy device to facilitate range-of-motion in the human hand, wrist, or forearm after surgery, trauma, rehabilitative therapy, or other events that resulted in limited wrist motion or stiffness. This device facilitates wrist therapy by utilizing gravity and leverage. The therapy device includes two generally isosceles triangular rigid sides functioning as top and bottom, joined by and narrowing to a point via a sandwiched solid wedge, a hand strap and wrist strap of a strong, soft material on the outside of the top rigid side. This device provides therapy to restricted tissue in the human hand, wrist, or forearm while applying passive tension during rehabilitation. Readily converting from supination or pronation therapy to extension or flexion therapy, and radial or ulnar deviation, the device can be used on the right or left hand. This invention provides a low cost, effective and simple to use wrist rehabilitation device.
