摘要： 目的了解非特异性下腰痛患者在行不同桥式运动时腰肌表面肌电活动的变化。方法选取正常对照与非特异性下腰痛患者各18 例，记录两组受试者行桥式运动、单足支撑桥式运动时的腰肌表面肌电信号均方根值。结果对照组行不同桥式运动时，双侧竖脊肌、多裂肌表面肌电配对比较均无显著性差异(P>0.05)；各时段组间同侧同名肌肉表面肌电比较无显著性差异(P>0.05)。患者组行桥式运动时，双侧腰肌表面肌电配对比较无显著性差异(P>0.05)；行单足支撑桥式运动时，支撑足侧竖脊肌肌电值
较对侧大(P<0.05)，前、中、后时段腰肌肌电值无显著性差异(P>0.05)。结论非特异性下腰痛患者行非对称性桥式运动时，双侧竖脊肌收缩力不平衡。

Abstract: Objective To investigate the features of surface electromyography of lumbar muscles in non-specific low back pain (NLBP) patients when they were practicing different types of bridging exercise. Methods 18 healthy subjects (control group) and 18 NLBP patients (NLBP group) were included and asked to practice bridging exercise with single and double feet. The root mean square (RMS) of surface electromyography of both sides of lumbar muscles were recorded. Results No significant difference was found in the control group. The RMS of erector spinae was more in the supported side than in the contra side for NLBP patients in bridging exercise with single foot. There was no significant difference among different time points in the same muscle. Conclusion The contractions of erector spinae in both sides are not equal in asymmetric bridging exercise in NLBP patients.
