System for Knee Extension Therapy

Abstract

The present invention concerns a system that is useful to apply controlled, gradual muscular stretching, and is particularly useful for knee extension therapy.

Description

TECHNICAL FIELD[0001]This application relates to a system for stretching a person's muscles, such as the hamstring muscles as well as the muscles and other tissues comprising the articular capsule of the knee joint.BACKGROUND[0002]The terms “hamstring,”“hamstrings” or “hamstring muscle” are generally used to refer to the three large muscles constituting the back of the upper leg. The hamstrings serve to flex the knee joint and extend the hip. Everyday activities as well as most athletic activities involve the repetitive contraction of the hamstring muscle. The hamstring muscle tightens as a result, and requires effective stretching to retain its full range of motion. In the absence of such stretching, the tight hamstrings will have a deleterious effect on the person's skeletal alignment, typically resulting in lower back and knee pain, as well as problems with posture.[0003]Full extension of the knee is often lost as a result of knee injury and related surgery. Careful and sustained...

Benefits of technology

[0008]In another embodiment, the system can be modified for primarily stretching the hamstring muscles. In this embodiment, the stretched leg extends generally vertically upwardly adjacent to a stationary vertical surface. The stretched leg is supported for controlled, slow, forced rotation abo
