ABSTRACT:
A therapeutic traction chair for extending the middle and lower back including a seat receiving the patient and a backrest. The seat and backrest comprise a subframe pivotally mounted to a supporting frame wherein the angle of the backrest to the vertical may be adjusted. Arm supports extend from the backrest under the armpits of a seated patient, and the seat is vertically adjustable relative to the backrest to drop the seat away from the backrest transferring the patient's weight to the arm supports placing the spine and back under traction and extension. The adjustment of the subframe and seat position is through an electric-powered actuator, and the arm supports may be positioned to an inactive storage condition.
