重复性经颅磁刺激联合感知提醒对脑卒中患者单侧忽略的影响研究

Treatment of Unilateral Neglect using Repetitive Transcranial Magnetic Stimulation (rTMS) and Sensory Cueing (SC) in Stroke Patients

  • 摘要: 【摘要】 目的 对比低频重复性经颅磁刺激(rTMS)联合感知提醒(SC)治疗与单独使用rTMS治疗对脑卒中亚急性期单侧忽略患者忽略严重程度、上肢功能以及日常生活活动能力的影响。方法 采用随机对照研究、评定者盲法设计,将33例右侧脑卒中后单侧忽略患者随机分为rTMS+SC组(n =16)和rTMS组(n =17)。在常规康复治疗基础上,rTMS+SC组患者同时接受rTMS以及SC治疗,rTMS组患者仅接受rTMS治疗。rTMS治疗采用经颅磁刺激仪,刺激左侧后顶叶皮层,刺激频率1 Hz,刺激强度为90%静息运动阈值,治疗时间为1次/d,5 d/周,连续治疗2周;SC治疗采用佩戴提醒腕表,每天累计提醒时间为3 h, 5 d/周,连续佩戴2周。治疗前及治疗2周后分别评定单侧忽略严重程度〔单侧行为忽略常规子量表(BIT-C)和凯瑟琳博格量表(CBS)〕,上肢运动功能〔上肢运动评分量表(FMA)、上肢活动量表(ARAT)〕以及日常生活自理能力〔改良巴氏指数(MBI)〕。结果 治疗2周后,两组患者各项指标均较治疗前有改善。与单纯rTMS治疗比较,rTMS+SC组在BIT-C方面改善更好(P <0.05)。其余CBS、上肢功能(FMA、ARAT)指标治疗后两组差异无统计学意义。结论 rTMS联合SC能更有效的改善脑卒中患者单侧忽略症状, 可望作为单侧忽略的多技术联合治疗策略之一在临床推广应用。

     

    Abstract: 【Abstract】 Objective To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) and sensory cueing (SC) for improving hemi-spatial attention deficits related to unilateral neglect, upper limb function and independence of stroke patients. Methods An assessor-blinded randomized controlled trial (RCT) was conducted. Eligible stroke patients were treated with rTMS (n =17) or rTMS combined with SC (n =16) in addition to conventional rehabilitation measures. rTMS was applied with low frequency (1 Hz) over the posterior parietal cortex (P5) of the lefthemisphere, 90% resting motor threshold, 900 pulses each session,one session per day, and 5 d per week for 2 weeks. SC was emitted using a wristwatch device attached to the hemiplegic arm for 2 weeks with a cumulative wear time of 3 h per day. The severity of unilateral neglect 〔behavioral inattention test conventional subtests (BITC), Catherine Bergego scale (CBS)〕, activity of daily living 〔modified Barthel index (MBI)〕, and upper limb function 〔Fugl-Meyer assessment (FMA), action research arm test (ARAT)〕 of the patients were measured pre- and post-interventions (immediately after 2 weeks' treatment) by an occupational therapist. Results BIT-C was relieved significantly over time in both groups. But rTMS+SC had greater improvement than rTMS alone (P <0.05). No significant differences was found between the two groups in other outcomes (CBS, FMA, ARAT). Conclusion rTMS combined with SC is better than rTMS alone for treating unilateral neglect in stroke patients.
