Abstract

Abstract A mechanical exercising or physical therapy device for the controlled progressive stretching and exercise of the legs of persons afflicted by diseases characterized by contracture of tendons and muscles of the legs and back. The device includes a table on which the patient may lie. It is provided with a pivoted back rest which can be raised and lowered mechanically and two individual leg rests which can be raised and lowered and also swung to either side, either individually or together. Each leg rest includes a frame in which the leg is supported. At its extremity, there is a mechanism for shackling the foot. An adjustable bridge member over the knee permits application of pressure to the knee in controlled increments to force the knee down to straighten the leg and stretch the muscles. A further adjustable mechanism is provided for pivoting the foot on its ankle to stretch the heel cords.
