Alterations in corticospinal coupling during force generation for supplementary motor area (SMA). Psycho-physiological interaction (PPI) analysis between ipsilesional SMA ( A ) and the spinal cord and overview of the slices displayed along the z axis. B , Comparison control (C) >stroke (S), controlled for maximum grip force. C , Patients with stroke: correlation with motor impairment, controlled for maximum grip force, age, side; Z thresholds, and image presentations are identical to Figure 3 (exception: | Z |>1.9 for the correlation between PPI-SMA and Fugl Meyer assessment of the upper extremity [UEFM]). au indicates arbitrary units; and NHP, Nine-Hole Peg Test.
