Microcomputer-based low-cost method for measurement of spatial and temporal parameters of gait

The instantaneous velocity of the forward-going foot is measured throughout the swing phase during several successive gait cycles using punched paper tapes attached to the feet. The velocity profiles thus obtained show clearly any asymmetry or departure from the normal walking pattern. The data are processed to provide the spatial and temporal parameters of gait, i.e. step lengths, stride times, double-support times, cadence and walking speed. The equipment is low-cost, easy to set up and use, and the results, which are presented on the VDU or as hard copy, are readily interpreted and related to the underlying pathology.
