摘要： 目的研究慢性非特异性下腰痛患者(CNLBP)悬吊运动疗法(SET)治疗前后站立位腰屈伸运动时竖脊肌、多裂肌表面肌电信号的变化特征。方法30 例CNLBP患者接受SET治疗，每周3 次，持续4 周。分别在治疗前后采集患者在站立位做腰屈伸运动时双侧竖脊肌(L1/2水平)和多裂肌(L4/5水平)在站立位、前屈运动、最大屈曲及回到直立位的表面肌电信号，分析平均肌电值(AEMG)，计算屈伸比(FRR)。结果治疗前患侧竖脊肌和多裂肌FRR均小于对侧(P<0.05)；治疗后双侧竖脊肌和多裂肌FRR无显著性差异(P>0.05)。结论SET治疗后，CNLBP患者患侧竖脊肌、多裂肌的主动活动机能得到改善，屈曲-放松现象部分恢复。

Abstract: Objective To investigate the changes of surface electromyographic signal during lumbar flexion-extension after sling exercise therapy (SET) in patients with chronic nonspecific low back pain (CNLBP). Methods 30 patients with CNLBP received SET, 3 times a week for 4 weeks. The surface electromyographic signals of erector spinae and multifidus of both sides were collected, when they were in erect position, flexion motion, maximum voluntary flexion, and back to erect position, before and after intervention. The average electromyogram (AEMG) was analyzed, and the flexion-relaxion ratio (FRR) was compared. Results The FRRs of both erector spinae and multifidus were lower in the painful side than in the healthy side before intervention (P<0.05). There was no significant difference in the FRRs of both erector spinae and multifidus between 2 sides after intervention. Conclusion SET may improve the active motion function of the erector spinae and multifidus of the painful side and recovery of flexion-relaxation phenomenon.
