Task performance of able-bodied individuals and amputees. (a) The number of foot placement errors per trial is depicted for able-bodied individuals (‘AB’) and below-knee amputees (‘BKA’). For BKAs, the error rate bar plots are stacked to illustrate that the majority of the errors were made by the prosthetic foot rather than the intact foot. The black bracket indicates that the error rate between the participant groups was significantly different. (b) Trial completion times for able-bodied individuals and below-knee amputees were not significantly different.
