| Research Abstract |
In order to know the best stimulation site of repetitive transcranial magnetic stimulation (rTMS) for spinocerebellar degeneration (SCD), we analyzed it using functional magnetic resonance imaging (fMRI). Twelve SCD patients were scanned while performing motor task. In SCD patients, network analysis showed significant interaction from the supplementary motor area (SMA) to the sensory motor cortex compared with control groups, suggesting the SMA as a best stimulation site for rTMS. Next, low-frequency rTMS over the SMA was performed in two SCD patients. Sub-analysis of International Cooperative Ataxia Rating Scale (ICRS) revealed that rTMS over SMA improved "Posture and Gait", and "Coordination movement in limbs" in SCD. These results suggested the efficiency and theoretical background of rTMS over SMA in SCD.
