| 摘要： |
| 目的: 对青少年特发性脊柱侧弯症(AIS)患者凸凹侧椎旁肌表面肌电比值与相应的Cobb角度进行相关关系分析研究。 方法: AIS患者25例，男7例，女18例，年龄11—21岁；所有患者均执行BST实验，采用芬兰ME6000型表面肌电仪记录患者凸、凹侧椎旁肌表面肌电信号时域指标平均肌电值（AEMG），计算凸凹侧AEMG比值，并与相应Cobb角度进行相关分析。 结果: AEMG比值与Cobb角度之间的相关系数为0.534，（P<0.01），有显著性意义。结论: AIS患者AEMG比值与Cobb角呈正相关，表明Cobb角度越大，凸凹侧的肌力差异越大，失衡越明显。 |

| Abstract: |
| Objective:To investigate the possible correlation between the convex/concave averaged electromyogram（AEMG） ratio of paravertebral muscles and Cobb′s angle in adolescent idiopathic scoliosis (AIS) patients.Method: Twenty five AIS patients were enrolled. 7 males, 18 females, with an age range from 11 to 21 years old. BST was carried out in all the patients enrolled. AEMG, a time domain index of surface electromyographic signals, of both the convex and the concave paravertebral muscles were recorded with a ME6000 sEMG instrument (Finland) in AIS patients, and the convex/ concave AEMG ratios were calculated accordingly. A correlative analysis between the convey concave AEMG ratio and the Cobb′s angles was performed. Results: the correlation index between the AEMG ratio and Cobb′s angle was 0.534(P<0.01). Conclusion: The convex/concave AEMG ratio of the AIS patients is positive correlated with it′s Cobb angle, suggesting that the bigger the Cobb angle is, the more significant the bilateral unbalance of muscle strength of paravertebral muscles of AIS patients is. |
