Baseline epoch muscle activity phase relative to clinical impairment. Values are means for each participant (n = 12, excluding participant J). Relative vastus medialis (VM) muscle activity phase in the paretic limb was calculated in comparison with the average during bilateral pedaling of the nonparetic VM (BNP). A: VM muscle activity phase during bilateral pedaling in the paretic limb (BP), relative to the Fugl-Meyer synergy subscore (FMS). B: VM muscle activity phase during unilateral pedaling in the paretic limb (UP), relative to FMS.
