低频重复经颅磁刺激治疗半侧空间忽略的临床研究

Effect of Low Frequency Repetitive Transcranial Magnetic Stimulation on Unilateral Spatial Neglect

目的探讨低频重复经颅磁刺激治疗半侧空间忽略症的临床疗效。方法将40例脑卒中所致半侧空间忽略症患者分为治疗组及对照组各20例,并对治疗组进行为期2周的低频重复经颅磁刺激治疗。在治疗前后,采用半侧空间忽略评估量表分别对两组患者进行评定。结果治疗前,两组患者半侧空间忽略程度无显著性差异(P>0.05);治疗后,治疗组半侧空间忽略程度较对照组改善(P<0.05);治疗后,治疗组中重度异常率较治疗前明显降低(P<0.05),对照组无显著性差异(P>0.05)。结论通过低频重复经颅磁刺激治疗,脑卒中所致半侧空间忽略程度明显改善。

Objective To explore the effect of low frequency repetitive transranial magnetic stimulation（rTMS） on unilateral spatial ne-glect（USN）.Methods 40 stroke patients with USN were divided into treatment group（n=20） and control group（n=20）.Patients in the treat-ment group were treated with low frequency rTMS for 2 weeks.The USN degree of these groups were evaluated before and after the treat-ment.Results There was no significant difference of USN degree between these groups before the treatment（P〈0.05）;Compared with the control group,the treatment group improved significantly after the treatment（P〈0.05）.The USN degree of patients in the treatment group decreased significantly after the treatment（P〈0.05）,while patients in the controlled group had no difference（P〉0.05）.Conclusion USN in-duced by stroke could be improved obviously through low frequency rTMS.
