ABSTRACT:
A novel form of crutch is provided which can be used, particularly by paraplegics, to move between sitting and standing positions. The crutch includes a unique foot mechanism which gives added stability to the user of a pair of the crutches during such sitting/standing transitions, and which can be retracted so as to avoid interference with normal crutch-aided walking. A set of such powered crutches, incorporating both power extension/retraction and power foot adjustment, are capable of extended powered operation with on-board electrical power, and use power only for adjustment and are self-locking into adjusted positions. The power assist of the crutches are controllable from switches strategically located by the crutch handles so the user can manipulate the control switches without releasing his/her hold on the crutch handles. Also disclosed is a unique method of assisting disabled persons, using such crutches, to move between seated and standing positions without further assistance.
