The offline effects of brain stimulation (type tDCS) on balance control after stroke

INTERVENTION: transcranial direct current stimulation (tDCS); 2mA for 15 minutes. Anodal, cathodal and sham stimulation will be applied on M1 in a random order across participants. CONDITION: Stroke, Stroke ; ; PRIMARY OUTCOME: The main outcome variable is the reaction time in a simple reaction time task and the onset of postural responses. SECONDARY OUTCOME: Relation between the effects of tDCS and structural imaging markers in stroke survivors. INCLUSION CRITERIA: People over 18 years old in the chronic phase after experiencing a supratentorial unilateral stroke (> 6 months ago) that resulted in a hemiparesis. Furthermore, healthy controls of similar age and young healthy controls (18‐30 years) will be included.
