Mean (± SE) Stride Length when subjects walked at 1.25 m/s using the exoskeleton (Exo) with no ropes engaged, the exoskeleton with r2-long engaged without and with ankle assistance (Ankle), the exoskeleton with r2-short engaged without and with ankle assistance, and without the exoskeleton. * represents a significant difference compared to Exo not engaged (p < 0.05) and # represents a significant difference compared to No Exo (p < 0.05)
