Epidural electrical stimulation for the treatment of chronic poststroke aphasia: still compulsory 6 years later!

Implanted cortical stimulation is foreseen to facilitate functional poststroke recovery. Until now, no study has concluded on its pathophysiological mechanism. We report a case of a 58-year-old patient for whom cortical stimulation triggered a drastic enhancement of speech performances. The effects remain reversible after 6 years of stimulation, reflecting intra/inter-hemispheric modulation.
