Abstract
Abstract A back traction device is disclosed that allows a patient or person to be seated in any type of seat and will relieve the pressure and tension on the disc of the lower back of the patient as much as possible. The back traction device comprises a halter with ribs that serve to transfer some of the pressure that is associated with setting in a chair when the patient is seated in the chair. The back traction device includes a halter and a traction member. The halter has strips of Velcro™ at an outward rear position that mate with Velcro™ portions on the traction device that is attached to a chair or the like. In one embodiment, the traction device comprises a member that has straps that allow it to be removably attached to a chair and, in a second embodiment, the Velcro™ traction device is permanently attached to the back of a chair. The second embodiment is particularly useful in a dedicated chair, for frequent use by people wearing such halter, such as a wheelchair.
