Variability coefficients calculated for gait speed (panel A), stance time (panel B), gait cycle (panel C) and stride length (panel D) under the three walking conditions: UW, FW and DT. In each panel the variability coefficients were reported for both HC (white and light grey) and FSHD (dark grey and striped columns) and for both body side (left: white and dark grey columns, right: light grey and striped columns) except for the gait speed. There was no difference between the two groups. DT, dual tasking; FSHD, facioscapulohumeral dystrophy; FW, fast walking; HC, healthy controls; SD, standard deviation; UW, usual walking.
