Abstract

This report focuses on investigating the data related to the human walk cycle with various perturbations. Then various muscle models, such as the Hill's muscle model, are examined. The human gait and all sub-phases of the gait cycle are presented. In the data, the ankle angle, center of pressure, and ground reaction force are compared between 2 degrees and 5 degrees perturbations that occur at 3 different time points in the gait. A perturbation is a deviation from the normal state caused by the tilt of the platform. It examines the reaction of the ankle with respect to the change in the gait from perturbations. Minimums, maximums, correlation coefficient, slope and different statistical tests were conducted. Calculations were completed to understand the influence of a perturbation on gait.
