Patients with adhesive capsulitis were clinically evaluated to establish whether pain elicited by pressure on the coracoid area may be considered a pathognomonic sign of this condition. The study group included 85 patients with primary adhesive capsulitis, 465 with rotator cuff tear, 48 with calcifying tendonitis, 16 with glenohumeral arthritis, 66 with acromioclavicular arthropathy and 150 asymptomatic subjects. The test was considered positive when pain on the coracoid region was more severe than 3 points (VAS scale) with respect to the acromioclavicular joint and the anterolateral subacromial area. The test was positive in 96.4% of patients with adhesive capsulitis and in 11.1%, 14.5%, 6.2% and 10.6% of patients with the other four conditions, respectively. A positive result was obtained in 3/150 normal subjects (2%). With respect to the other four diseases, the test had a sensitivity of 0.96 and a specificity ranging from 0.87 to 0.89. With respect to controls, the sensitivity and specificity were 0.99 and 0.98, respectively. The coracoid pain test could be considered as a pathognomonic sign in physical examination of patients with stiff and painful shoulder.
患有粘连性肩关节囊炎的患者进行了临床评估，以确定在喙突区域施加压力时引起的疼痛是否可被视为该病症的特有征象。研究组包括 85 例原发性粘连性肩关节囊炎患者、465 例肩袖撕裂患者、48 例钙化性肌腱炎患者、16 例肱盂关节炎患者、66 例肩锁关节炎患者和 150 例无症状受试者。当喙突区域的疼痛比肩锁关节和肩峰前外侧区域的疼痛严重 3 分（VAS 量表）时，测试被认为是阳性。在粘连性肩关节囊炎患者中，96.4%的患者测试结果为阳性，而在其他四种疾病患者中，阳性率分别为 11.1%、14.5%、6.2%和 10.6%。在 150 名正常受试者中，有 3 名（2%）测试结果为阳性。与其他四种疾病相比，该测试的灵敏度为 0.96，特异性范围为 0.87 至 0.89。与对照组相比，灵敏度和特异性分别为 0.99 和 0.98。喙突疼痛试验可被视为肩部僵硬和疼痛患者体格检查中的一种特有征象。
