It also gives the hardware details of the velocity meter which is used to monitor the muscle activity with speed of walking. Software has been developed for system initialization, data acquisition, processing of acquired data, and data display for five channels. The developed equipment will be useful to clinicians for enhancing the understanding of a patient's dynamic performance.</p>  a0010-4809
