Fig. 4.
Mean and standard deviations of the overall perturbation effect 6S (see text for details) for medio-lateral (ML) and anterior-posterior (AP) margins of stability (MoS) after the ipsi-lateral sway (SwyI), contra-lateral sway (SwyC), acceleration (Acc), deceleration (Dec), visual (Viz) and auditory (Aud) perturbations. Black dots represent values for young adults whereas white dots represent older adults. Significantly different pairwise comparisons are indicated at the top per perturbation type in italic
