A method for obtaining a synthetic representation of the joint angle time-courses at different walking velocities is presented, based on a computerized procedure. Hip, knee and ankle joint angles are measured by electrogoniometric devices and checked on line for their reliability. One stride only for each walking speed is selected as representative of the adopted cadence. For each joint a tridimensional representation of angle time-course versus stride frequency or versus gait speed is performed so that speed-dependent variations can be analyzed. Ten normal (seven males and three females) and three prosthetized subjects have been tested by this method. In normal as well as in pathological subjects individual features could be easily detected and the method proved to be useful for a functional gait evaluation.
