For each stroke patient is indicated: age, gender, lesion location, hemiparetic side, etiology (type of stroke: H = hemorrhagic; I = ischemic), time since lesion (days), total ARAT (Action Research Arm Test) score, MVC grip force in kg in the hemiparetic and non-affected hand, % MVC in the hemiparetic hand compared to the non-paretic hand, performance of the Moberg pick-up Test (time in s) for both hands, % of proprioception, and tactile sensibility (Semmes-Weinstein mono-filament test) for both hands. Bottom two lines: mean and standard deviation in stroke patients and control subjects
