  1. BG: Basal Ganglia. MCA: Middle Cerebral Artery. ACA: Anterior Cerebral Artery. PCA: Posterior Cerebral Artery. V4: intradural vertebral artery. ICA: Internal Carotid Artery. NA: No Data Available. FMA-LE: Fugl-Meyer Assessment Lower Extremity. JND: Just-Noticeable-Difference. IU: Interval of Uncertainty
  2. * Based on the normality, JND threshold, lesion volume, and FMA-LE data are presented as the mean, and IU data as the median in this table. † Measures of proprioceptive acuity (JND threshold/IU) were above the control group indicating impaired ankle proprioception. For S12 no brain MRI data were available and lesion volume could not be computed. S08 had impaired ankle position sense assessed by Erasmus MC modified Nottingham Sensory Assessment
