摘要: 目的探讨疲劳诱发试验中肌肉疲劳与疼痛发生的相关性。方法2016年7月至10月,招募21例青年女性健康志愿者进行疲劳诱发试验,采集试验前、试验过程中和试验后表面肌电信号的均方根(RMS)和中值频率(MF),采用Borg疲劳量表、疲劳视觉模拟评分(VAS)评价疲劳程度,测定最大自主收缩力(MVC)、压力疼痛阈值(PPT)等数据。根据试验后是否诱发疼痛分为两组,比较试验前后差值。结果Borg疲劳量表评分、疲劳VAS评分、MVC、RMS和MF在疲劳诱发前后有非常高度显著性差异(Z>6.064, P<0.001)。两组间疲劳诱发试验前各项指标无显著性差异,试验前后VAS评分差(t=-4.112, P=0.001)、部分测试点RMS差(t>2.385, P<0.05)有显著性差异;接受者操作特征曲线分析显示疲劳VAS评分差预测疼痛发生的最佳临界点为3.45,敏感性100%,特异性81.8%。结论疲劳诱发试验中,疲劳VAS评分差对疼痛发生有一定的预测价值;RMS差与疼痛发生存在一定关联;未发现Borg疲劳量表和PPT在预测疼痛发生中的价值。

Abstract: ObjectiveTo explore the relationship between muscle fatigue and pain in lumbar muscle fatigue induced test. MethodsFrom July to October, 21 healthy female volunteers were subjected to the fatigue induced test. Their root mean square (RMS) and median frequency (MF) of the surface electromyography were collected, their fatigue were assessed with Borg Fatigue Scale and Visual Analogue Scale (VAS), and their maximal voluntary contraction (MVC) and pressure pain threshold (PPT) were measured, before, during and after experiment. They were divided into pain or no-pain groups according to the symptom, and the differences before and after test were compared. ResultsThere was significant difference in the scores of Borg Fatigue Scale and VAS, MVC, RMS, and MF after test (Z>6.064, P<0.001). There was significant difference between two groups in all the data before test, and there was significant difference between two groups in the difference before and after test of the VAS score (t=-4.112, P=0.001) and RMS (t>2.385, P<0.05) in some points. Receiver operating characteristic curve analysis showed that the optimal cut-off point of VAS score difference was 3.45 in predicting the pain onset, with sensitivity of 100% and specificity of 81.8%. ConclusionFor the fatigue induced test, the fatigue VAS score difference may predict the induced pain, and RMS difference associate with the occurrence of pain. No significant is observed of the Borg Fatigue Scale and PPT.
