The boxplots for the point-by-point variance (PPV) grouped by feedback condition (A) and pin stiffness (B). The solid-colored boxes are for the condition with EMG feedback, while the striped boxes correspond to the condition with incidental feedback only. The performance of the amputee participants is denoted with red asterisks. Statistically significant pairs are marked with horizontal bars (∗p < 0.05, ∗∗∗p < 0.01)
