Apparatus for use in rehabilitation of a patient with a weight bearing restriction on one or both legs includes a pair of vertically movable horizontally elongated platforms and a pair of corresponding vertically fixed platforms. The movable platforms are connected to a mechanism which applies an upwardly directed preselected force so that as the patient walks with a foot on the movable platform, the movable platform will descend if the patient places a greater weight corresponding to the preselected force. A patient may walk with both feet on movable platforms in which case the weights may be selected for each platform or the patient may walk with one foot on the movable platform and one foot on a fixed platform. The platforms move in a vertical plane arcuately in one embodiment and in a vertical plane linearly in a second embodiment. The weights may be moved relatively to the pivot point and, in addition, the movable platform may be locked in its upward position in this latter embodiment.
