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 1Hz, 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.
目的
评估低频重复经颅磁刺激（rTMS）对一名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，以1Hz的频率，在运动前区皮质施加1200次经颅磁刺激脉冲，强度为运动阈值（MT）的90%；共进行5次治疗。
结果
我们的患者在伯克、法恩和马斯登扭转肌张力障碍量表（BFM）的颈部亚组中观察到50%的改善。
结论
BFM量表的改善支持了运动前区皮质的rTMS可能减轻PSD特定运动症状的观点。
