There is also a significant difference with SS metric and a strong trend in the differences with PTT (p = 0.149) and SM (p = 0.105) metrics between control and high functional stroke group, which suggest that the performance of able-bodied subjects in the trajectory tracking task tend to be more accurate (PTT), stable (PTT) and with better speed consistency (SM, SS) than high functional stroke subjects.
