Abstract: The present invention utilizes a user's arm strength opposed by large stretch bands attached to the harness to achieve 100% of the traction force or “pull-weight.” The principal components of the device are an anchoring system, such as a frame, and a harness, which are used simultaneously as part of a single system. The user lies upon a body support atop the frame and uses his/her arm strength to slide forward by pulling with his/her hands against a harness fastened around the user's waist. The user accomplishes the sliding forward by pulling on handles attached to the top of the frame, while the harness is attached to the bottom of the frame. The effect is distraction of the lower spine. The unique mode of action of the device utilizes the user's own arm strength to achieve a completely variable traction force. The user is in complete control of the amount of traction force to be delivered at all times without any dependence upon electricity to generate force.

Abstract: For the treatment of spinal damage in medical physiotherapy, the patient's spine is stressed via the pelvis by longitudinal forces on the legs in such a way that the setting of displaced spinal components is promoted and the muscles are strengthened. With this device the tensile forces are applied to the feet by spring components which are tensioned by means of cables from the movements of the pins of linear movement components driven by an electric motor. The frequency and amplitude of these tensile forces can be changed via a control unit and thus phase shifts between the forces acting on the legs can be adjusted. During the exercises the patient can adjust the exercise programme by actuating controls connected to the supporting grips. The success of the therapy can be improved by fitting heating elements in the backrest to provide heat treatment for the patient's muscles.
