thesis / dissertation description
Assumptions regarding the bilateral symmetry of normal gait are common in both clinical and research settings. When assessing any aspect of human gait, the effect of horizontal velocity (HV) on the biomechanical characteristics of the activity is of great importance. The purpose of the present study was to investigate the influence of horizontal walking velocity on the bilateral symmetry of gait in a normal population. Multiple peak and temporal ground reaction force (GRF) parameters were collected from a pre-screened subject pool of 21 able-bodied individuals at each of three HV conditions (slow, normal & fast) and two contact foot (CF) conditions (right & left). Statistical analysis of this GRF data was accomplished by means of a series of 2 x 3 repeated measures ANOVAs. The most interesting findings were two significant interaction effects of HV and CF for the stance time and the maximum vertical force at push-off (Fz3) parameters. (Abstract shortened by UMI.)
