摘要:
Objective To identify the surface electromyographic (sEMG) characteristics of bilateral stemocleidomastoid muscles in infants with congenital muscular torticollis (CMT) after rehabilitation.Methods One hundred and twenty two infants were enrolled from Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine between January 2013 and December 2015,including 63 cases receiving rehabilitation (treatment group) and 59 cases without rehabilitation (control group).The sEMG parameters of bilateral sternocleidomastoid muscles in cervical neutral,left and right rotation and stretching posture in the supine position were retrospectively collected before and after treatment/follow-up;and the root mean square (RMS) was analyzed.Results Before treatment,the RMS values of the affected side in cervical neutral position,cervical rotation and stretching posture were significantly lower than those of the unaffected side in both groups(t=15.758 and 11.950,4.871 and 4.746,4.142 and 4.318,P<0.01).In the follow-up for control group,the RMS values of the affected side in cervical neutral position,cervical rotation and stretching posture were significantly lower than those of the unaffected side (t=10.692,2.198 and 3.239;P<0.01,=0.03 and <0.01).In the treatment group there were no significant differences in the RMS values in cervical neutral position,cervical rotation and stretching posture between affected side and unaffected side after treatment(t=1.647,1.090 and 0.136,P=0.10,0.28 and 0.89).Conclusion Rehabilitation reduces the difference of the RMS values between the affected and unaffected sternocleidomastoid muscles in infants with CMT.%目的 研究康复治疗后先天性肌性斜颈患儿双侧胸锁乳突肌表面肌电信号特征变化.方法 回顾性选择2013年1月至2015年12月在上海交通大学医学院附属新华医院进行康复治疗的先天性肌性斜颈患儿63例作为康复治疗组,选择同期59例未进行康复治疗的先天性肌性斜颈患儿作为对照组,比较分析随访/治疗前后仰卧中立位、颈部旋转和颈部牵伸下双侧胸锁乳突肌的肌电信号,计算时域均方根值(RMS).结果 治疗前,对照组和康复治疗组患儿中立位、颈部旋转和牵伸时患侧胸锁乳突肌的RMS值均低于健侧,差异均有统计学意义(t=15.758、11.950、4.871、4.746、4.142、4.318,均P<0.01).随访时,对照组患儿中立位患侧胸锁乳突肌的RMS值低于健侧(t=10.692,P<0.01),颈部旋转和牵伸时患侧胸锁乳突肌的RMS值低于健侧,差异均有统计学意义(t=2.198、3.239,P=0.03、<0.01);治疗后,康复治疗组患儿中立位、颈部旋转和牵伸时双侧胸锁乳突肌RMS值差异均无统计学意义(t=1.647、1.090、0.136,P=0.10、0.28、0.89).结论 康复治疗可以改善先天性肌性斜颈患儿双侧胸锁乳突肌兴奋性差异.
