Experimental Datasets

Data from: A Perturbation Mechanism for Investigations of Phase-Dependent Behavior in Human Locomotion

The dataset contains sagittal-plane leg joint kinematics, ground reaction forces, and EMG activity from one stride starting at heel strike on the perturbation platform, which randomly moved the stance foot in the anterior or posterior direction. These perturbations effected a phase shift in the gait cycle without substantially deviating from the nominal kinematic orbits of the leg joints. Only the right leg of each subject was perturbed, but both legs' kinematics are recorded. This data can be used to test different hypotheses and models of human locomotor control.

Data from: Evidence for a Time-invariant Phase Variable in Human Ankle Control

The data contained herein includes kinetic and kinematic data acquired during walking trials, while a subject walked a across a walkway. A perturbation device was recessed into the walkway and randomly applied a two or five degree incline perturbation to the ankle as subjects walked across the platform. The perturbations occurred at one of four timing intervals, namely 100, 225, 350 and 475 ms following heel strike. During each trial, subject ankle angle and ground reaction force data were acquired, including location of the center of pressure for each subject.
