目的：评估低频重复经颅磁刺激（rTMS）对原发性节段性肌张力障碍（PSD）患者症状的影响。方法：使用八字形线圈，在前运动皮层上以 1 Hz 的频率发出 1200 个 TMS 脉冲，强度为运动阈值 (MT) 的 90%；共举办了5次会议。结果：在我们的患者中观察到，Burke、Fahn 和 Marsden 扭转肌张力障碍量表 (BFM) 的颈部子集减少了 50%。结论：BFM 量表的减少支持了运动前皮层的 rTMS 可能减少 PSD 中特定运动症状的概念。
Objective: To evaluate the effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) on the symptoms of a patient with primary segmental dystonia (PSD). Method: 1200 TMS pulses at a frequency of 1 Hz, over the premotor cortex, with an intensity of 90% of the motor threshold (MT), using an eight-shaped coil; a total of 5 sessions were carried out. Results: A reduction of 50 percent in the neck subset of the Burke, Fahn and Marsden torsion dystonia scale (BFM) was observed in our patient. Conclusion: The reduction in the BFM scale supports the concept that rTMS of the premotor cortex may reduce specific motor symptoms in PSD.
