Fig. 2From: Effects of supraspinal feedback on human gait: rhythmic auditory distortionStep time (in ms) for all participants under the different experimental conditions: No Metronome, Isochronous Condition A, Increasing and Decreasing Frequency or vice-versa (see Fig. 1). The vertical lines indicate the instants of the metronome frequency transitions. The horizontal lines represent the mean (solid) and standard deviation (dashed). Top row left panel shows a wide variation representing different combinations of step length for the prescribed treadmill speed. Top row right panel shows the narrow band resulting from the introduction of the metronome beat. Lower row panels show the subliminal increase and decrease (and vice-versa) which are closely followed by the subjectsBack to article page
