Abstract
A bowler's wrist and forefinger support which comprises a rigid body adapted to extend dorsally from the forefinger to a location on the forearm above the wrist. The distal portion of the support extends over and partially encases the forefinger throughout its entire length. The proximal portion is cylindrically curved to fit generally around the back of the hand, wrist and forearm. The support restricts backward movement of the forefinger to an optimal angular range of 15 to 20 degrees forward with respect to the axis of the hand.
