Biomarkers to Predict Gain From Therapy in Motor Stroke

The aim is to determine predictors of treatment response, i.e gain from rehabilitation training, in post stroke upper limb deficits. The investigators will like to answer the following question: "What is this patient's potential for recovery, given his profile?" The investigators propose to conduct a longitudinal physiopathological study on the stroke patients with motor deficits who entered the rehab center of Pitié Salpêtrière hospital. The investigators will benefit from the organization, which is already in place (clinical asssessments and training) to add MRI, TMS and EEG recordings, as well as genotype analysis before the training offered in the rehabilitation unit. The investigators will repeat these assessments after the training (immeadiately and 6 weeks after).
