5. Study Description

Brief Summary
This study evaluates the effect of a unique session of inhibitory rTMS (cTBS) over the contralesional posterio parietal cortex (PPC) on the spatio-temporal parameters of a pointing movement performed by stroke patients with their paretic upper limb. It will also assess the effects on the resting motor threshold of both hemispheres and on parietopremotor connectivity. To achieve theses aims, the real cTBS stimulation will be randomly counterbalanced with a SHAM stimulation (in a second session) in a crossover design. Assessments will be performed before and after each stimulation session.
