目的探索完全性脊髓损伤后肠道功能障碍患者的盆底肌表面肌电信号特征.方法 15例完伞性脊髓损伤患者(观察组)和15例正常人(对照组)参加本项研究,应用表面肌电生物反馈刺激仪经盲肠内采集盆底肌静息状念(10 s)、快速收缩(2 s×3)、持续收缩(10 s)时的表面肌电均方根值(RMS),并对2组盆底肌不同状念下的数值进行分析与比较.结果与对照组相比,观察组在盆底肌静息时的RMS最大值(16.61±2.83)和平均值(13.52±2.22)均明显高于对照组[(8.41±5.55)和(3.45±1.53)],组间相比差异有统计学意义(P<0.01);脱察组组内比较,持续收缩时RMS最大值(20.24±13.99)和平均值(13.36±2.39)、快速收缩时的RMS平均值(13.40±2.31)与静息时RMS最大值和平均值比较,差异无统计学意义(P>0.05).结论表面肌电可作为评定完伞性脊髓损伤后神经源性肠道功能障碍状况和盆底肌功能的量化指标,对进一步制定脊髓损伤患者盆底肌协调训练计划,改善肠道功能障碍具有一定的临床应用价值.

Objective To investigate changes of surface electromyogr8phic(sEM G)signal of pelvic floor muscles in complete spinal cord injury(cSCI)patients with neurogenic bowel dysfunction.Methods Fifteen hospitalized patients with cSCI(observation group)and fifteen normal subjects(control group)were involved in this study.The root mean square(RMS)of sEMG signals were collected at pelvic floor muscles with rectal surface electrode when subjects'pelvic floor muscles were rest(10 s),fleetly contract(2 s×3),continually contract(10 s).Both groups'data of different contracting states of pelvic floor muscles were analyzed and compared.Results The max RMS and average RMS(16.61±2.83,13.52±2.22)at pelvic floor muscles'rest in observation group were higher than that in control group(8.41±5.55,3.45±1.53).There was statistical difference between two groups(P<0.01).In the subjects of observation group max RMS and average RMS(20.24±13.99,13.36±2.39)at continual contraction and average RMS(13.40±2.31)at fleet contraction were nearly the same as RMS value at pelvic floor muscles'rest.There was no statistical difference between these two states(P>0.05).Conclusion The sEMG could be a quantitative index in assessing function of pelvic floor muscles and the neurogenic bowel dysfunction after cSCI.It can supply some clinical value in framing the training of pelvic floor muscles and improving the bowel dysfunction.
