Research and Construction of Trajectory Measurement System for Limb Joints Motion of Human Body

Li Zheng(Dept of Engineering Physics,Tsinghua University,Beijing,100084)Yang Yanming;Yuan Bo(Dept of Modern Physics,USTC,Hefei,230027)  
Gait analysis is an important subject in modern biomedical engineering. This article introduces the trajectorymeasurement system for limb joints motion of human body in tri-dimensional space by using the ultrasonic princi-ple of determination of distance,pulse modulation and districts encoding. The system is easy to use,fast,accu-rate and inexpensive.(
