A new system for three-dimensional kinematic trajectory acquisition and analysis--I. The application of an ultrasonic technique to human gait analysis.
This paper discusses some techniques of kinematics analysis, and describes a new system for movement recording and analysis. The new system, which is inexpensive and easy to use, consists mainly of some ultrasonic wave transmitters, receivers, a distributive multiprocessor system and software. The system can record kinematics parameters of anatomical landmarks (e.g. space coordinates, movement trajectories and angles of hips, knees and ankles). Such a system, combined with foot pressure equipment and a force plate, forms an advanced gait analysis system.
