Example of YHP step time data as quantified by the GaitRite (white square) and BWM (black diamonds): (a) all steps, arrows indicate the greater variability of estimated step times for the GaitRite (small) and BWM (large); (b) correct allocation of left steps and right steps, some step times are closely matched (good agreement and correlations); (c) an example of where incorrect allocation of left and right steps may have occurred (poor agreement and correlation), e.g. P1 of left step. P1–P5 indicate the numerous passes the YHP completed over the GaitRite.
