Fig. 4From: Improving postural stability among people with lower-limb amputations by tactile sensory substitutionPerformance variables of CoP excursion with and without sensory substitution during quiet standing. The range of CoP in the AP direction (A) and in the ML direction (B) and the average CoP displacement (C) within a second were plotted separately for the control and the amputation group. The error bars denote standard errorsBack to article page
