40 acute subjects will be split into 5 groups. Each group will receive one of the following tDCS montages : anodal, bilateral, cathodal, extracephalic or placebo.

Subjects will receive, in addition to conventional rehabilitation, 2mA for 20 mins of their attributed tDCS, 5 times a week.

Evaluations will take place before the first stimulation period (48h post stroke), after 1, 2, 3 and 4 weeks. Evaluations consist of the Wolf Motor Function Test, the Fugl Meyer, and the Semmes Weinstein Monofilament Test

40 acute subjects will be randomized and split into 5 groups.

Each group will receive one of the following tDCS montages :

Anodal : Anode placer over the affected primary motor cortex, cathode over contralateral supra orbital area Bilateral : Anode placer over the affected primary motor cortex, cathode over unaffected motor cortex Cathodal : Cathode placer over the unaffected primary motor cortex, anode over contralateral supra orbital area Extracephalic : Anode placer over the affected primary motor cortex, cathode over right shoulder Placebo : anode montage but current is ramped up over 15 secondes, then ramped down.

Subjects will receive, in addition to conventional rehabilitation (±1.5h/weekday), 2mA for 20 mins of their attributed tDCS, 5 times a week.

Evaluations will take place before the first stimulation period (48h post stroke), after 1, 2, 3 and 4 weeks. Evaluations consist of the Wolf Motor Function Test, the Fugl Meyer, and the Semmes Weinstein Monofilament Test

All researchers, therapists, data analysis and patients are blinded by a code system implemented in the tDCS machine
