Abstract: A multipositioning power mobility aid for physically challenged children is provided. The power mobility aid provides a transition to a power wheelchair. The power mobility aid includes a multipositioning main frame that allows a child to be placed in a sitting, semi-standing or standing position without requiring multiple adjustments. The back support rotates to a nonsupporting position to facilitate placing a child in or removing a child from the power mobility aid. The back support then locks into an upright supporting position after the child is positioned in the power mobility aid. The power mobility aid includes an adjustable arm that supports the user-operable input device in multiple locations.

Abstract: 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.
