【摘要】：目的:应用ROC曲线法,探讨超声测量计算腕管综合征(CTS)患者腕管水平和旋前方肌近端1/3处的正中神经横断面积与神经肌电图检测严重程度结果的相关性。方法:84例患者140个手腕经肌电图诊断为CTS。在腕管水平(CSAC)和旋前方肌近端1/3处(CSAP)进行正中神经横断面积的测量。计算CSAC和CSAP横断面积的差值(△CSA)以及CSAC和CSAP横断面积的比值(R-CSA)。结果:CTS患者经NCS诊断分级为轻度、中度、重度三组,三组平均△CSA分别为(4.6±2.5)mm~2、(7.2±2.2)mm~2、(10.9±4.7)mm~2;平均R-CSA分别为(1.5±0.3)、(1.9±0.4)、(2.5±0.8),各组间均有显著差异(P0.01)。△CSA和R-CSA区分轻度和中度CTS的最佳临界值分别为6 mm~2和1.7 mm~2,特异性分别为82.6%和78.3%,敏感性分别为80.0%和76.3%,准确性分别为80.6%和76.7%。区分中度和重度CTS的最佳临界值分别为9 mm~2和2.2 mm~2,特异性分别为87.5%和83.8%,敏感性分别为62.2%和51.4%,准确性分别为79.5%和73.5%。结论:ROC曲线分析表明,△CSA和R-CSA有助于反映CTS患者的严重程度。
[Abstract]:Objective: to investigate the correlation between the level of carpal tunnel and the transverse area of median nerve at 1 / 3 of proximal end of anterior circumflex muscle and the severity of electromyography (EMG) in patients with carpal tunnel syndrome (CTSs) by using ROC curve method. Methods 140 wrists of 84 cases were diagnosed as CTS by electromyography. The transverse area of the median nerve was measured at the level of the carpal tunnel (CSAC) and the proximal end of the anterior circumflex muscle (1 / 3). The difference between CSAC and CSAP and the ratio of CSAC to CSAP were calculated. Results according to NCS, the patients were classified as mild, moderate and severe. The average CSA of the three groups was 4.6 卤2.5 卤2.5 卤2.2mm, respectively, and the average R-CSA of the three groups was 10.9 卤4.7 卤4.7mm2, respectively, and the average R-CSA of the three groups was 1.5 卤0.3 卤0.40, respectively. There were significant differences between the three groups (P 0.01). The best critical values of CSA and R-CSA for differentiating mild and moderate CTS were 6 mm~2 and 1.7 mm-1, the specificity was 82.6% and 78.3%, the sensitivity was 80.0% and 80.0%, respectively. The accuracy was 80.6% and 76.7%, respectively. The best critical value for distinguishing moderate and severe CTS was 9 mm~2 and 2.2 mm-2, the specificity was 87.5% and 83.8%, the sensitivity was 62.2% and 51.4, and the accuracy was 79.5% and 73.5%, respectively. Conclusion CSA and R-CSA are helpful in reflecting the severity of CTS patients.
