目的：尺侧腕伸肌（ECU）肌腱协同试验是一种用于评价慢性尺侧腕背疼痛的简单而独特的诊断方法，该方法对ECU施加单独的张力，而不会对其他结构施加很大的应力。本研究的目的是探讨ECU协同测试的诊断性能，以检测ECU异常的sonography.Methods-Forty受影响的手腕，从39个连续的慢性背尺侧手腕疼痛，持续超过1个月的ECU协同测试和超声检查。评价ECU协同试验检测ECU异常的敏感性、特异性、阳性预测值和阴性预测值。我们比较了ECU协同试验在ECU异常组和非ECU异常组之间的结果，还比较了ECU协同试验结果阳性组和阴性组以及ECU异常组和非ECU异常组之间患者的年龄、性别和症状持续时间。82.4%和78.3%。ECU协同试验结果在ECU异常组和无ECU异常组之间有显著差异（P <0.01）。任何groups. Conclusions之间的年龄，性别，或症状持续时间没有显着差异，这项前瞻性研究的结果支持这一假设，即ECU协同测试可能是一个有用的挑衅机动检测慢性背侧尺侧腕关节疼痛患者的ECU异常。
Objectives-The extensor carpi ulnaris (ECU) tendon synergy test is a simple and unique diagnostic maneuver for evaluation of chronic dorsal ulnar-sided wrist pain, which applies isolated tension to the ECU without greatly stressing other structures. This study aimed to investigate the diagnostic performance of the ECU synergy test to detect ECU abnormalities on sonography.Methods-Forty affected wrists from 39 consecutive patients with chronic dorsal ulnar-sided wrist pain that continued for greater than 1 month were examined with the ECU synergy test and sonography. The sensitivity, specificity, positive predictive value, and negative predictive value of the ECU synergy test to detect ECU abnormalities were evaluated. We compared the results of the ECU synergy test between groups with and without ECU abnormalities and also compared the ages, sexes, and symptomatic durations of the patients between groups with positive and negative ECU synergy test results and between the groups with and without ECU abnormalities.Results-The sensitivity, specificity, positive predictive value, and negative predictive value were 73.7%, 85.7%, 82.4%, and 78.3%, respectively. There was significant difference in the ECU synergy test results between the groups with and without ECU abnormalities (P < .01). There was no significant difference in age, sex, or symptomatic duration between any of the groups.Conclusions-The results of this prospective study support the hypothesis that the ECU synergy test could be a useful provocative maneuver to detect ECU abnormalities in patients with chronic dorsal ulnar-sided wrist pain.
