Figure 4From: Self-selected gait speed - over ground versus self-paced treadmill walking, a solution for a paradox Differential effect of visual virtual scenery on self- selected gait speed. For each subject, gait speed values during TM walking were normalized with respect to the GS value. Box plots for normalized TMS1 – TMS4 are plotted for EXPERIMENT A (gray boxes) and for EXPERIMENT B (light green boxes). The horizontal dashed line represents the GS (i.e., = 1).Back to article page
