Resumen

Three-dimensional human range motion measurement system is developed by inertial sensor technology and wireless bluetooth acquisition technology. This paper describes the internal structure and the data processing method of the measurement system in detail. This measurement system is capable of testing the range of each joint motion, and can be easily carried to the rehabilitation hall, wards and other occasions for test and evaluation. It plays an extremely important role in its application in monitoring rehabilitation process, assessing disability, doing scientific research, and in many other fields. Three experienced teachers tested the range of motion of cervical spine, lumbar spine, right side of the shoulder, elbow, wrist, hip, knee, ankle, and other joints of ten college students. Through comparing the test results and the obtained results of this measurement system by using the method of paired samples T-test, they got the results that the bilateral significance level (Sig) was greater than 0.05, which can be considered that there were no significant differences between these two sets of results. Then it verifies the validity of the data in this system.
