Mean Z-Scores in Ipsilesional and Contralesional Region of Interests for Task-Based Activation, Resting-State Sensorimotor Network Connectivity Maps, and Frequency Domain Metrics

	Motor task (p = 0.0005)	rsfMRI SCA (p = 0.0004)	rsfMRI ALFF (p = 0.02)	rsfMRI fALFF (p = 0.03)
CL ROI (mean Z scores ± SD)	2.14 ± 0.46	0.89 ± 0.23	1.01 ± 0.14	1.07 ± 0.082
IL ROI (mean Z scores ± SD)	1.72 ± 0.42	0.71 ± 0.23	0.87 ± 0.13	0.99 ± 0.076

Group level analysis for all four maps (tbfMRI, SCA, ALFF, and fALFF) of all 12 patients, showing statistically significant differences between IL and contralesional ROIs in each map.

ALFF, amplitude of low-frequency fluctuations; CL, contralesional; fALFF, fractional ALFF; IL, ipsilesional; ROI, region of interest; rsfMRI, resting-state functional MRI; SCA, seed correlation analysis; SD, standard deviation; tbfMRI, task-based functional MRI.
