Abstract

Gait observations of normal subjects and patients with knee disabilities are presented. Time-distance measurements and ground reaction force parameters are reported in relation to walking speed. Regression analysis is used to establish simple functional relations between ground reaction force amplitudes and walking speed.

It is shown that basic time distance measurements observed over a range of walking speeds can be useful indicators of gait abnormalities associated with knee disabilities. For example, clinical improvement after treatment is found to be consistent with changes in these gait parameters. These results indicate the usefulness and importance of considering gait measurements in relation to walking speed when attempting to classify gait abnormalities.
