目的:主要目的是根据本诊断测试研究中的电诊断检查(EDX)参考标准,确定横截面面积肿胀率(CSASR)的诊断和治疗目的。
方法:首先,具有单侧腕管综合征(CTS)等症状的患者,肘管综合征(CuTS),和radial神经压迫(RNC)进行了EDX和超声检查。第二,超声阳性的患者计算病变神经的CSASR。根据先前建立的CSASR标准,每位患者被归类为患有或没有周围神经卡压,对于那些符合诊断标准的人,建议非手术或手术治疗.然后,灵敏度,特异性,阳性预测值(PPV),负预测值(NPV),超声诊断和治疗决策的准确率(ACC)是根据实践中历史上使用的EDX参考标准计算的。
结果:总灵敏度,特异性,PPV,NPV,超声诊断的ACC分别为93.4、85.2、94.7、82.1和91.3%。超声波治疗决策是哪一个,分别,83.3、52.2、78.4、60.0和73.2%。
结论:CSASR对CuTS的诊断阈值的敏感性和Youden\指数高于其他超声方法。CuTS的CSASR诊断阈值具有潜在的诊断作用,但当前日期仍不足以支持CTS或RNS的潜在诊断作用.没有足够的证据表明CuTS的CSASR可以单独用于诊断。需要进一步的研究来确认CSASR的诊断作用。当前结果表明,这种超声检查方法不适用于治疗决策。
OBJECTIVE: The primary goal was to determine the performance of the cross-section area swelling rate (CSASR) for diagnostic and therapeutic purposes based on the reference standard of electrodiagnosis examination (EDX) in this diagnostic test study.
METHODS: First, patients with symptoms like unilateral carpal tunnel syndrome (CTS), cubital tunnel syndrome (CuTS), and radial nerve compression (RNC) underwent EDX and ultrasound examination. Second, patients with positive ultrasound were calculated for the CSASR of diseased nerve. Based on previously established CSASR criteria, each patient was categorized as having or not having peripheral nerve entrapment, and for those meeting diagnostic criteria, non-surgical or surgical treatment was recommended. Then, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy rate (ACC) of ultrasound diagnosis and therapeutic decision-making were calculated based on the reference standard of EDX that had been historically used in the practice.
RESULTS: The total sensitivity, specificity, PPV, NPV, and ACC of ultrasound diagnosis are respectively 93.4, 85.2, 94.7, 82.1, and 91.3%. Which of therapeutic decision-making by ultrasound are, respectively, 83.3, 52.2, 78.4, 60.0, and 73.2%.
CONCLUSIONS: The sensitivity and Youden\'s index of CSASR diagnostic threshold for CuTS is higher than other ultrasound methods. The CSASR diagnostic threshold for CuTS has a potential diagnostic role, but the current date is still not enough to support the potential diagnostic role for CTS or RNS. There is insufficient evidence to suggest that CSASR for CuTS can be used in isolation for diagnosis. Additional research is needed to confirm the diagnostic role of CSASR. The current results suggest that this ultrasound examination method is not suitable for therapeutic decision-making.
