Body sway of young healthy subjects assuming each of four postures and either afforded feedback or not. Kinesthetic haptic feedback reduced body sway in young healthy subjects regardless of posture or ground condition. All index values exhibited significant (p < 0.05) reductions in body sway upon application of kinesthetic haptic feedback. Differences (feedback/no feedback) in the MLT data from subjects in posture P2 were of borderline significance (p = 0.055). (a) MVD (b) PD (c) MLT (d) APT. *p-value < 0.05.
