The coracoid pain test (CPT) could contribute to the diagnosis of frozen shoulder (FS) with palpation. However, due to assessor performance these values might be unreliable. Therefore, the aim was to explore the diagnostic accuracy of an instrument-assisted CPT and two alternative approaches (pain severity and side comparison) for assistance in the diagnosis of FS. Patients with FS and healthy age-matched controls were recruited. All participants underwent the instrument-assisted CPT on both shoulders with a pressure algometer. Sensitivity, specificity, and likelihood ratios were determined for the three approaches. In total, 35 patients with FS and 35 healthy participants were included. The original approach was positive in eight participants (11.4%), with only sufficient specificity to draw a conclusion. The pain severity approach was positive in 31 participants (44.3%) with sufficient sensitivity, specificity and likelihood ratios. The side comparison approach was positive in 10 participants (14.3%) with excellent specificity and positive likelihood ratio. The specificity of the instrument-assisted CPT can be used to increase the probability of FS with both the original and alternative approaches. Only the pain severity approach can draw a conclusion with a negative test result. This study should be repeated with a cross-sectional design to strengthen and confirm the conclusions.
喙突压痛试验（CPT）可以通过触诊帮助诊断冻结肩（FS）。然而，由于评估者的表现，这些值可能不可靠。因此，本研究旨在探讨仪器辅助 CPT 以及两种替代方法（疼痛严重程度和侧面对比）在 FS 诊断中的辅助诊断准确性。招募了患有 FS 和年龄匹配的健康对照组的患者。所有参与者均在双肩使用压力测痛计进行仪器辅助 CPT。确定了三种方法的敏感性、特异性和似然比。共纳入 35 名 FS 患者和 35 名健康参与者。原始方法在 8 名参与者（11.4%）中呈阳性，仅有足够的特异性得出结论。疼痛严重程度方法在 31 名参与者（44.3%）中呈阳性，具有足够的敏感性、特异性和似然比。侧面对比方法在 10 名参与者（14.3%）中呈阳性，具有极好的特异性和阳性似然比。仪器辅助 CPT 的特异性可用于增加原始和替代方法的 FS 概率。只有疼痛严重程度方法可以通过阴性测试结果得出结论。应使用横断面设计重复这项研究以加强和确认结论。
