Figure 5From: Stepping stability: effects of sensory perturbationMaximum (Emax) and minimum (Emin) peak squared fractional errors from 2 second interval bins during 10 seconds following the perturbation. Peak error Emax at perturbation (p = .019) and peak error Emin after 10 seconds (p = .028) were greater for balance impaired patients compared to healthy subjects.Back to article page
