Does variability of footfall kinematics correlate with dynamic stability of the centre of mass during walking?

Gait variability is a sensitive metric for assessing functional deficits in individuals with mobility impairments. To correctly represent the temporal evolution of gait kinematics, nonlinear measures require extended and uninterrupted time series.<br>The full-body gait patterns of twenty healthy subjects were captured during five walking trials (at least 5 minutes) on a treadmill under different weight perturbation conditions with both weight reductions (of 40 and 20% using a harness labelled har40 and har20) as well as weight additions (of 40% and 20% using weight vests labelled wei40 and wei20) and these were compared against normal weight condition (normg).<br><br>Data is presented at .mat files for all subjects and conditions.<br><br>
