Temporal-Spatial Parameters. Data is shown for the rock surface (RS; black) and level ground (LG; cyan) at four, evenly-spaced, controlled speeds. Data for the prosthetic limb (P) is given by ‘○’ while data for the intact limb (I) is given by ‘×’. A) The average and B) within-subject variability of step length (SL), step time (ST), and step width (SW) across subjects are shown for each condition. Error bars represent ± 95% confidence intervals about the mean. *Statistically significant main effects for walking speed (p < 0.05), =Statistically significant main effects for walking surface (p < 0.05), §Statistically significant main effects for limb (p < 0.05)
