Numerical calculate analysis method of ankle joint stretching treatment

Abstract

In this paper, a method of simple geometrical analysis method during ankle joint stretching treatment using numerical calculation was proposed. The stretching of the ankle joint is an important medical treatment that physical therapist (PT's) help their patients to recover their ability to walk and to prevent contracture. Since the ankle treatment requires a large amount of force (nearly equal to the subject's weight) and precise angle control at the same time, manual treatment by PTs has not been replaced by mechanical treatment systems and the mechanism of the treatment has not been analyzed mathematically. In order to realize developing the effective mechanism of the treatment, numerical calculation analyze the geometrical relationships between Ankle joint, Hip joint, Thenar and pushing device rotation center during the treatment. The proposed numerical calculation method will effectively work to develop the mechanical systems of ankle joint stretching treatment. of proceedings paper for the 56th Conference of Japanese Society for Medical and Biological.
