目的：探讨腰部竖脊肌表面肌电指标屈曲伸直比(flexion-extension ratio,FER)诊断非特异性慢性腰背痛的可靠性。
方法：根据诊断性研究方案，选择非特异性慢性腰背痛患者73例和对照者86例，测量屈伸运动时腰部竖脊肌表面肌电指标屈曲伸直比，用SPSS软件绘制受试者工作曲线(ROC),确定屈曲伸直比诊断非特异性慢性腰背痛最佳临界值，计算屈曲伸直比诊断慢性腰背痛的敏感度、特异度、准确度。
结果：根据受试者工作曲线，确定FER≥0.68为慢性腰背痛，FER<0.68为无慢性腰背痛标准，屈曲伸直比对慢性腰背痛诊断的敏感度、特异度、准确度分别为78.1%,95.3%,87.4%.
结论：表面肌电指标屈曲伸直比诊断非特异性慢性腰背痛敏感度、特异度和准确度高，可靠性强，可作为慢性腰背痛诊断的客观指标。 |

Abstract:
Objective: To evaluate the reliability of flexion-extension ratio(FER)of lumbar erector muscle in surface EMG for the diagnosis of nonspecific chronic low back pain.
Methods: According to diagnostic study strategies,73 patients with chronic low back pain and 86 controls were recruited in this study,FER of lumbar erector muscle were recorded in surface EMG for all the subjects.The critical value of FER for the diagnosis of nonspecific chronic low back pain was selected according to the receiver operator characteristic curve by SPSS. Sensitivity,specificity and accuracy were calculated and analyzed as well.
Results: The FER in patients group was significantly higher than that in the control group. The critical value of FER was 0.68 with sensitivity,specificity and accuracy was 78.1%,95.3% and 87.4% respectively.
Conclusion: FER of lumbar erector muscle might be practically applied as an objective indicator on the diagnosis of nonspecific chronic low back pain in surface EMG. |
