摘要
目的评估不同损伤程度的脊髓损伤（SCI）患者肛门括约肌表面肌电的变化。方法根据美国脊柱损伤协会（ASIA）2006年颁发的SCI神经学分类国际标准，110例残损分级为A级、B级、c级和D级的SCI患者分别为A组、B组、C组和D组，应用标准的Glazer盆底表面肌电评估方案及设备，对患者进行肛门括约肌表面肌电测定，并对检测结果进行统计。结果B组与A组之间表面肌电的差异无显著性意义（P〉0．05）；而c组、D组与A组相比，在快速收缩、持续10s收缩、持续60s收缩阶段的表面肌电平均值和最大值的差异均具有统计学意义（P〈0．01）；D组与c组相比，上述指标的差异也具有统计学意义（P〈0．05或P〈0．01）。结论SCI患者在快速收缩、持续10s收缩、持续60s收缩阶段肛门括约肌的表面肌电检测值明显低于正常；Glazer盆底肌表面肌电评估方案的检测是一种非侵入性、便捷、实时的检测方法，有助于定量地评估SCI患者盆底肌的变化。
Objective To identify differences in the anal sphincter surface electromyography （sEMG） variables in spinal cord injury （SCI） subjects with different severities. Methods One hundred and ten SCI patients＇ impairments were classified as ASIA A, B, C or D using the International Standards for the Neurological Classification of Spinal Cord Injury. The evaluation was performed using sEMG equipment with an inserted anal sensor electrode and the Glazer pelvic floor muscle sEMG protocol. The sEMG variables were recorded and compared. Results There was no significant difference in sEMG variables between groups A and B, but the mean and maximum sEMG values of groups C and D in flick contractions （ 1 s） , tonic contractions （ 10 s） , and endurance contractions （60 s） were significantly higher than those of group A. Compared with group C, the mean and maximum sEMG values of group D were all significantly higher. Conclusions The sEMG data from the anal sphincter during contractions decreases significantly after SCI. Glazer＇s pelvic floor muscle sEMG protocol is a noninvasive and convenient real-time assessment. It is a useful complementary tool for quantitative assessment of the pelvic floor muscles of SCI patients.
