Table note: PVI - periventricular venous infarction, AIS - arterial ischemic stroke, TDC - typically developing control, DM1 - distal M1 occlusion, PM1 - proximal M1 occlusion, AHA - assisting hand assessment, BBTA - box-and-blocks test of the affected hand, BBTU - box-and-blocks test of the unaffected hand. Vascular territory for the AIS group was categorized using T1-weighed MRI scans.
