To assess the excitability of the motor system, we studied 11 patients with task-specific dystonia and 11 age-matched normal subjects. The dominant side was affected in nine of the patients. We delivered transcranial magnetic stimuli at different stimulus intensities and with different levels of muscle facilitation to the side contralateral to the side of electromyographic recording, and recorded motor evoked potentials (MEPs) from the flexor carpi radialis muscles bilaterally. The threshold intensity for eliciting MEPs at rest did not differ between patients and normal subjects. We compared the affected side in patients with the dominant side in normal subjects. With facilitation, the percentage of the area of the MEP to the M wave (MEP area%) was similar in both groups at low stimulus intensities, but with increasing stimulus intensity the increase in the MEP area% was greater in patients than in normal subjects (ANOVA, p < 0.001). The increase in MEP area% was similar in both groups with increasing facilitation levels. The duration of the silent period was similar in patients and normal subjects. We conclude that cortical motor excitability is increased in dystonia.
