Listed here are parameter estimates for the model variables (and p values). Key: *Significant at p ≤ 0.05. ns, non-significant (p > 0.05); ipsi, ipsilesional; M1, primary motor; SMA, supplementary motor area; LPM, premotor regions; S1, primary somatosensory area; SII, secondary sensory region; AMAT, Arm Motor Ability Test.
