Abstract: Disclosed is portable and easily securable mobilization belt for performing physical therapy on an affected joint comprising a continuous loop of inelastic woven material. The loop comprises an expanded section for securing in a door jamb and a cushioned section for contact with the patient's affected joint. Alternatively, the loop can be secured by wrapping around a vertical stanchion of a heavy piece of furniture or other solid object that will not move. In use, the affected joint is placed in the loop adjacent the cushioned section. With the loop taut, the patient provides resistance against the belt to create mobilization of the affected joint.
