Baseline and adaptability tests. In Baseline (A), the monitor was switched off when participants walked at their preferred speeds for 10 min. In step length adaptation (B), the monitor displayed a line (step length target) and participants were tasked to match peaks of step length line graphs with the line on the screen, until the line was removed. In minimum toe clearance (MTC) height adaptation (C), the monitor displayed a line (MTC target) for 10 steps, and the task was to match the lowest peak before the highest peak by lifting the foot higher
