    摘要： The present invention is a prosthetic prehensor with two members extending in the same direction. One of the members rotates about a parallel axis removed from the first member until it contacts the first member. In the preferred embodiment, the two members are curved plates, one simulating a thumb and the other being wider and simulating a palm. The thumb plate rotates around a base plate which is coupled to the end of an arm. The thumb plate can contact the palm plate in either of two directions. This allows two types of gripping for fine objects and larger objects. The use of plates that are curved allows for a more aesthetic design than metal hooks.

    摘要： A tennis training aid can be used to teach proper wrist and racket position for swings such as a forehand ground stroke, two-handed backhand stroke, or volley. A training aid includes a forearm attachment member that can be quickly and easily attached to a player's forearm. A wrist positioning member can be attached between the forearm attachment member and the player's racket to maintain proper wrist angle and racket position. A first wrist positioning member can be used for a forehand ground stroke or two-handed backhand stroke, while a second wrist positioning member can be used for volleys. The forearm attachment member can include a rotatable member, and the wrist positioning member can be slightly elastic, in order to allow the racket to move slightly with respect to the wrist, and to allow for slight wrist movement, in order to provide a natural feel for the player.
