Note that patients are not ordered chronologically (No.), but according to the following tables 3 and 4 for continuity. The two lowest rows show descriptive statistics for patient (Pat) and control (Ctr) groups. Abbreviations: GF = grip force, Hem = affected hemisphere; LQ = laterality quotient for handedness according to the Edinburgh Handedness Questionnaire (where +100 denotes strongly right-handed); JTT = Jebsen Taylor Test score; MI = primary motor cortex (precentral gyrus); NIHSS = National Institutes of Health Stroke Scale; TOR = tactile object recognition; 2PD = two-point discrimination; PM = premotor cortex (superior and middle frontal gyri anterior to precentral gyrus); PPT = pressure perception threshold; PPC = posterior parietal cortex (superior and inferior parietal lobe); SI = primary somatosensory cortex (postcentral gyrus).
*Values are mean (SD) for ratio data, median (interquantile range) for ordinal data, and number for count data. ° As identified on routine diffusion-weighted and fluid-attenuated inversion recovery scans. -, data not available (task could not be performed).
