Outline of Final Research Achievements |
We recorded electroencephalograms (EEGs) over the bilateral sensorimotor cortex from a patient suffering from chronic writer’s cramp. The patient was asked to suppress an exaggerated beta frequency component in the EEG during EEG control via brain-machine (brain-computer) interface (BMI) system. Significant decrease of the beta frequency component during handwriting was confirmed, and was associated with clear functional improvement. The current study suggests that a BMI can give explicit feedback of ongoing cortical excitability to patients with dystonia and allow them to suppress exaggerated neural activity, resulting in functional recovery.
