A new system for three-dimensional kinematic trajectory acquisition and analysis .1. 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. Copyright (C) 1996 Elsevier Science Ltd for IPEMB.
