  • Patent number: 6666796
    Abstract: Apparatus to assist human walking, incorporating in combination first and second longitudinally extending strut members that are relatively movable, longitudinally, and adapted to transmit body associated loading; the first strut member or members operatively connected to a rack and/or to the user's body; the second strut member or members slaved, i.e. operatively connected to the user's foot or feet, ankles or shoes, to move therewith; and a control that responds to step-by-step treading to control relative movement of the strut members. Such loading is controllably transferred back and forth between left and right pairs of strut members, in response to treading.
