- W4387662008 abstract "Objective: To analyze the efficacy of different targets low-frequency repetitive transcranial magnetic stimulation (rTMS) for the treatment of tremor Parkinson's disease(PD). Method: A total of 82 patients with primary PD who were admitted to the Department of Neurology, Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 1, 2020 to March 31, 2021 were prospectively collected. According to the clinical characteristics of major movement disorders, 82 patients with tremor type (TD) were selected to enroll.The patients were randomly divided into 3 groups at a 1∶1∶1 ratio according to the randomized coding sequence of the trial: the primary motor cortex (M1) group with 26 cases, the cerebellum group with 26 cases and the dual-site (M1, cerebellum) group with 30 cases. All patients were treated with 1 Hz low-frequency stimulation of the corresponding target once a day for 5 days a week for 2 weeks, a total of 10 times; The dosage remained unchanged during the treatment for all groups. Before and after 2 weeks' treatment, the patients were assessed with the Unified PD Rating Scale (UPDRS) and PD Quality of Life Questionnaire-39 (PDQ-39) without medication. Cortical excitability, namely transcranial magnetic stimulation motor evoked potential (TMS-MEP), [including resting motor threshold (rMT) and active motor threshold (aMT) examinations], timed up and go (TUG) and electromyographic tremor were conducted. Result: There were 82 patients, 39 males and 43 females, with an average age of (67±8) years. Before the treatment, there was no statistically significant difference in the evaluation indicators among the three groups (all P>0.05). After the treatment, the differences of the UPDRS-Ⅲ score [(38.9±2.5) vs (29.2±3.6) ], UPDRS tremor score [(23.7±2.1) vs (14.6±3.1) ], TUG time [(44.8±3.1) s vs (33.7±4.1) s], tremor amplitude [(480±126) μV vs (276±94) μV], PDQ-39 score [(51±13) vs (45±13) ], rMT [(36±17)% vs (43±13)%], and aMT [(26±16)% vs (31±12)%] were statistically significant (all P<0.01) from those before the treatment. There was no statistical difference in the above factors between the M1 group and cerebellum group (all P>0.05). There was no statistically significant difference in tremor peak frequency among the three groups before and after the treatment (all P>0.05). Conclusions: Dual-site low-frequency rTMS can improve PD tremor, while M1 or cerebellar low-frequency rTMS does not significantly improve PD tremor. Its mechanism may be to improve PD tremor symptoms by regulating cortical excitability.目的: 分析不同靶点重复经颅磁刺激(rTMS)治疗震颤型帕金森病(PD)的疗效。 方法: 前瞻性收集2020年4月1日至2021年3月31日就诊于上海交通大学医学院附属新华医院神经内科门诊的原发性PD患者,依据主要运动障碍临床特征选择震颤型(TD)82例入组,受试者按1∶1∶1比例根据试验随机编码的序列分为3组,即初级运动皮质区(M1)组26例、小脑组26例和双靶点(M1、小脑)组30例,每组均给予相应靶点1 Hz低频刺激,每天治疗1次,每周治疗5 d,持续治疗2周,共10次;所有组的常规药物治疗期间剂量保持不变。治疗前、治疗后2周在患者未服药状态下进行统一PD评定量表(UPDRS)、PD生活质量问卷-39(PDQ-39)评定,并测量皮质兴奋性即经颅磁刺激运动诱发电位(TMS-MEP)[包括静息运动阈值(rMT)和活动运动阈值(aMT)检查]、“起立-行走”计时测试(TUG)及肌电图震颤分析检查。 结果: 82例患者,男39例,女43例,年龄(67±8)岁。治疗前,3组患者的评价指标差异均无统计学意义(均P>0.05)。治疗后双靶点组的UPDRS-Ⅲ评分[(38.9±2.5)分 比(29.2±3.6)分]、UPDRS-震颤子评分[(23.7±2.1)分比(14.6±3.1)分]、TUG时间[(44.8±3.1)s比(33.7±4.1)s]、震颤波幅(480±126)μV比(276±94)μV、PDQ-39评分[(51±13)分比(45±13)分]、rMT[(36±17)%比(43±13)%]、aMT[(26±16)%比(31±12)%],与治疗前比较差异均有统计学意义(均P<0.01),而M1组和小脑组上述各指标差异均无统计学意义(均P>0.05)。震颤峰频率3组治疗前后差异均无统计学意义(均P>0.05)。 结论: 双靶点低频rTMS能改善PD震颤,而M1或小脑低频rTMS对PD震颤改善不明显,其机制可能是通过调节皮质兴奋性从而改善PD震颤症状。." @default.
