RHOD and Stroke: These weights were different between stroke subjects and controls for the contralesional (DOTGROUP pathology effect: F(2,47) = 42.21, p < 0.001) and ipsilesional arm (pathology effect: F(2,47) = 35,41, p = 0.001); see Figure 6A. Specifically, for stroke subjects, the DELT-ant had a higher contribution (weight) in the first synergy, the DEL-pos had a higher contribution in the third synergy, while RHOM and INFR had a lower contribution in the first synergy and higher in the third synergy in both arms.
