Abstract

This study explored the directional specificity of fear of falling (FoF) effects on the stabilizing function of anticipatory postural adjustments (APA). Participants (N = 71) performed a series of lateral leg raises from an elevated surface in three conditions: in the “Control condition”, participants stood at the middle of the surface; in the two test conditions, participants were positioned at the lateral edge of the surface so that the shift of the whole-body centre-of-mass during APA for leg raising was directed towards the edge (“Approach condition”) or was directed away from the edge (“Avoidance condition”). Results showed that the amplitude of APA was lower in the “Approach condition” than in the “Control condition” (p
