Development of measurement system for range of motion of wrist

Abstract

Goniometer and flexible Goniometer are used for measuring range of motion (ROM). However the method of measuring ROM of wrist with Goniometer has many problems. For examples, it can not measure wrist's motion mixed with motion of ulnar and radial flexion and palmar and dorsal flexion, it is difficult for dividing wrist's motion from motion of pronation and supination by arm and it has limitation on measurable ROM due to low elasticity of Goniometer. Therefore, we are developing the new type measurement system for ROM of wrist. In this paper we explain the measurement system for ROM of wrist. And we measure the ROM of healthy parson by using the measurement system. From measured data, we confirmed that measurement system can measure the ROM.
