| Popis: | 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. ________________________________________________________________________________ RESUMO Objetivo: Investigar o efeito da estimulação magnética transcraniana repetitiva (EMTr) de baixa freqüência nos sintomas de um paciente com distonia segmentar primária (DSP). Método: 1200 pulsos a uma freqüência de 1Hz, sobre o córtex pré-motor, a uma intensidade de 90% do limiar motor (LM), usando uma bobina em forma de 8. Foram realizadas 5 sessões. Resultados: Uma redução de 50% no sub-item "pescoço" na escala de distonia de torção de Burke, Fahn e Marsden (BFM) foi observada no paciente em questão. Conclusão: A redução na escala BFM corrobora a idéia de que a EMTr sobre o córtex pré-motor pode reduzir sintomas motores específicos na DSP. |
