Abstract

Provided is a novel physical therapy system and device that can be manually operated by a post-operative patient without the need of professional on site assistance, wherein the degree of movement of the limb or joint of interest is measured and recorded so as to provide a record of the progress of the prescribed post-operative therapy for immediate feedback to the patient as well as for long term data recordation for the therapist or physician.
