Sway parameters of healthy adults (HA), Parkinson's disease (PD) and multiple sclerosis (MS) patients. (A) sway area, (B) velocity in antero-posterior (AP) direction, (C) velocity in medio-lateral (ML) direction, (D) acceleration in AP direction, (E) acceleration in ML direction, (F) jerk in AP direction and (G) jerk in ML direction. The black horizontal lines indicate a significant difference between the groups, the grey horizontal lines indicate a tendency toward a difference between the groups. * indicates a significant difference compared to the side-by-side stance, # indicates a significant difference compared to the semi-tandem stance.
