The mean square jerk (mean ± standard deviation) grouped by feedback condition (A) and pin stiffness (B). The solid-colored bars are for the EMG feedback condition, while the striped bars are for the condition with incidental feedback only. The performance of the amputee participant is denoted with red asterisks. Statistically significant pairs are marked with horizontal bars (∗∗p < 0.01, ∗∗∗p < 0.001)
