目的:采用表面肌电图(sEMG)检测技术对青少年特发性脊柱侧弯症(AIS)患者脊柱旁凸、凹侧椎旁肌肌电活动时域指标变化规律进行初步探讨.方法:AIS患者25例,男7例,女18例,年龄11-21岁;正常对照组少年14例,男4例,女10例,年龄12-19岁;两组受试者均执行BST实验、抬物实验,采用ME6000型表面肌电仪记录受试者双侧椎旁肌表面肌电信号时域指标平均肌电值(AEMG)、频谱面积(SPA).结果:AIS患者脊柱旁顶椎区凸、凹侧椎旁肌AEMG(凸侧 106.76±47.73μV/s,凹侧67.93±26.1 μV/s,P＜0.01),SPA(凸侧 11.01±8.81 m2,凹侧4.38±3.14m2,P＜0.01),差异具有显著性意义;正常对照组椎旁肌左、右侧表面肌电值差异无显著性意义.结论:AIS患者脊柱旁顶椎区凸、凹侧椎旁肌肌电活动不对称,表面肌电图可用作评定AIS脊柱旁凸、凹侧肌电活动差别的客观检查之一,具有较好的临床应用价值.

Objective: Using surface electromyographic (sEMG) techniques to investigate the patterns of time domain indexes of surface electromyographic signals of adolescent idiopathic scoliosis (AIS) patients' paraspinal muscles. Method: Twenty-five AIS patients were enrolled, included 7 males and 18 females, aged 11 to 21 years. Forteen healthy adolescents, included 4 males and 10 females, aged 12 to 19 years, were set as control. Adolescents in both groups undertook the Biering Sorensen test (BST), the object-lifting test and semi-bridge test. A ME3000P sEMG instrument was applied to record the electromyographic activities of paraspinal muscles (convex /concave) of all subjects, and the time domain indexes: averaged EMG parameters (AEMG) and spectrum area (SPA) were analyzed. Result: The differences of AEMGs and SPAs between the convex side and the concave side of paraspinal muscles at the zone of apex vertebrae of AIS patients were of statistic significance (AEMGs: convex side 106.76± 47.73μV/s vs concave side 67.93±26.11μV/s, SPAs: convex side 11.01±8.81m~2 vs concave side 4.38±3.14 m~2, both P＜0.01). The AEMGs of healthy controls' paraspinal muscles on both sides showed no significant difference. Conclusion: Electromyographic activities of paraspinal muscles (convex /concave) at the zone of apex vertebrae of AIS patients are asymmetric. sEMG can be one of the objective examinations used to evaluate the differences of electromyographic activities of paraspinal muscles(convex /concave) of AIS patients, and may have a promising value in clinical practice.
