Acute stroke patient will undergo one month (20 sessions) of physical therapy and anodal tDCS.

Patients will undergo functional outcomes measured at 48h post onset, 7,14,21,28 days, 3 and 6 months and one year post onset.

Recruitment :

Patients with acute stroke (24-48h after stroke) who have upper and / or lower sensorimotor deficits

• Treatment : After being selected according to the inclusion and exclusion criteria of this study, patients will be randomized and placed in one of two groups: placebo (P) or transcranial anodic stimulation (A).

Once placed in one of two groups, patients will all receive intensive physiotherapy for functional improvement in order to increase motor, postural and motor control. This physiotherapy will be established 5 times a week (Monday to Friday).

In addition to physiotherapy, the patient will have electrodes placed on his head, attached via a system of straps, to deliver either a continuous current (A) or no current (P) and at a rate of 5 times per week for 4 weeks. Neither the physiotherapist nor the patient will know what treatment he will have received.

• Evaluations and measurements:

Patients will be required to perform functional tests of the upper limb (Wolf Motor Function Test (WMFT)), filmed and timed, a test of spasticity (Tardieu) as well as to answer certain questionnaires concerning their perception of the evolution of the disease and their disability (Stroke Impact Scale, Barthel Index), their emotional state (HADS), if they have experienced side effects, sensitivity test with monofilaments or Semmes and Weinstein test, the Fugl Meyer, the timed up and go, the test of 10m, the four step square test, the berg balance scale, the postural assessment scale and the trunk impairment scale. These evaluations will take place at Day 0 (corresponding to the first day after the 48h of strict bedtime), Day 7, 15, 30, 90, 6 months and 1 year. They will be done in two stages, on two successive days, so as not to exhaust the patient.

Inclusion Criteria:

• Woman or man
• Between 18 and 80 years old
• First ever stroke
• Capable of signing the consent form

Exclusion Criteria:

• One on the TSST (in high and relatively high risk sections)
• Previous neurological or orthopedic pathologies affecting limbs
• Cognitive deficits

The device is preprogrammed by a third party non participating in any element in the study. They then chose (using opaque envelopes) the treatment code for each participant.
