Measures are reported as means ± SD (n); t-tests are reported as t(df) = t-value; and F-tests are reported as F(Dfn, DFd) = F-value. WMFT, Wolf Motor Function Test; MAL, Motor Activity Log; Dfn, the degree of freedom for the stroke subjects; DFd, for the healthy subjects; aff, affected; JTT, Jebsen-Taylor Test; FAS, functional ability scale;
