Cortical reorganization in multiple sclerosis after intrathecal baclofen therapy

Our objective was to assess the role of Intrathecal Baclofen Therapy (ITB) in the cortical reorganization in a patient affected by multiple sclerosis (MS) undergoing physical therapy. We reported a case of a woman affected by MS and severe spasticity, who performed an fMRI examination, before and after the ITB implantation. The subject showed controlateral motor cortex activation after motor task. After a month of ITB implantation, patient showed ipsilateral and controlateral motor cortex activation although with a broader extension. fMRI examination supported the hypothesis of a central influence in patients who undergo physiotherapy and therapy with ITB.
