Fig. 1From: Effects of supraspinal feedback on human gait: rhythmic auditory distortionSchematic representation of the three experimental conditions subdivided into eleven phases. The insert shows the three situations that may occur when trying to synchronize footfall and beep: when the footfall (marked by an x) happens after the auditory cue (positive relative phase), when it happens with the cue (relative phase zero) and when it happens before the cue (negative relative phase)Back to article page
