Abstract
Abstract There is disclosed a hand and finger exercise device particularly useful in combatting various arm and hand ailments, such as "tennis wrist" and "tennis elbow". The device includes a main cylindrical member, substantially of the diameter of a tennis racquet handle, adapted to be grasped in the palm of a user. Two elasticized straps run the full axial length of the member, at the side wall of the cylinder. One of these straps fits over the four fingers of the user's hand, adjacent the knuckles thereof, for maintaining the exercise device in place. The second strap fits over the four fingers of the user's hand, adjacent the finger tips. A third, thumb-receiving strap, which also runs along the axial length of the member but which extends only partially down the side wall, receives the thumb of the user. The device may be used with either of the user's hands, with the user squeezing the cylindrical member and thereafter flexing his fingers and thumb outwardly, against the forces presented by the straps.
