NDPs of the end-effector-pair-wise comparison of individual muscle synergies. NDPs were averaged across participants (means indicated by the black circles) and ranked from the best matching muscle synergies (S) to the least matching muscle synergies between two end-effectors. Each panel presents the results of the comparison of individual muscle synergies between two end-effectors. Vertical bars represent the 95% confidence interval determined with bootstrap statistics, whereas colored dots represent data of individual participants. Asterisks indicate mean NDPs that are significantly different from threshold (horizontal dashed line, significance determined with the 95% confidence interval)
