We claim:
1. A walking system for assisting a person to stand in an upright position and for alternately moving the legs to cause a walking movement, comprising:
- (a) a wheeled walker of a height permitting its upper part to be grasped by the hands of an erect user of the system,
- (b) a normally vertical leg brace extending along the outside of each leg which is pivotally supported at its upper end in relation to the body at the level of the hip joint, and is connected to the leg below the knee joint,
- (c) pneumatically operated means for moving the brace of each of the legs in a counter-clockwise direction about the pivotal support at its upper end from its normal vertical position to a position inclined forwardly from that support, and
- (d) pneumatically operated means for then moving the brace of the same leg in a clockwise direction about the pivotal support at its upper end from the forwardly inclined position to a vertical position.
