Abstrakt		Normal gait is characterised by a high level of inter-leg symmetry of gait parameters. Therefore, efforts in rehabilitation of amputees are directed at the construction of a prosthesis which provides normal leg function and allows a more symmetrical gait. Analysis of the gait of trans-tibial amputes was performed when they were ambulating at their own freely selected speed and at a faster speed. The effect of speed on selected gait parameters in each was evaluated and the influence on symmetry established by comparing the inter-changes for each of the selected parameters. The faster gait trail effected significantly all temporal and distance parameters in both legs but not the level of symmetry between legs. At the faster speed, the hip angles at heel-strike and during swing and the knee angle during load response, in the normal leg, and the knee angle during, swing in the amputed leg, all increased significantly. Speed of gait significantly affected symmetry between knee angles as reflected by the increased differences measured during load response (from 2.62+_.5.2 to 7.06 +_4.2 degrees) and during toe-off (from 1.80 +_7.4 to 9.50 +_9.1 degrees). Timing and sequence of selected gait events, as related to stride time, were not significantly affected by speed of gait. These results might contribe to a better understanding of gait characteristics in trans-tibial amputes and provide design guidance for prosthetic components.
