The magnitude of humeral torsion (HT) affects the internal and external rotation range of motion at the shoulder. Currently imaging is required to quantify the HT angle, however, factors such as cost and non-availability of imaging to musculoskeletal clinicians limits its use. The aim of this study was to examine the validity of palpation of the bicipital tuberosities as an alternative to imaging for quantifying HT angles. The bicipital-forearm angle, an indirect measure of HT, was measured using palpation and real-time ultrasound imaging in 25 subjects. The agreement among the two methods was excellent with the Intraclass Correlation Coefficient (3,k) = 0.92, and the mean difference between the two methods was -0.2° (SD 4.1°) with 95% limits of agreement of -8.3° to 7.9°. Pearson's correlation coefficient (r) among the two methods was 0.85. In a clinical setting, palpation appears to be a practical alternative to US imaging for measuring HT.
肱骨扭转（HT）的程度会影响肩部的内外旋转活动范围。目前需要通过影像学来定量 HT 角度，但是影像学的成本和可用性限制了其在肌肉骨骼临床医生中的应用。本研究旨在探讨触诊肱二头肌结节作为替代影像学方法来定量 HT 角度的有效性。使用触诊和实时超声成像测量了 25 名受试者的肱前臂角度，该角度是 HT 的间接测量指标。两种方法之间的一致性非常好，组内相关系数（3，k）为 0.92，两种方法之间的平均差异为 -0.2°（标准差为 4.1°），95%一致性界限为-8.3°至 7.9°。两种方法之间的 Pearson 相关系数（r）为 0.85。在临床环境中，触诊似乎是 US 成像测量 HT 的一种实用替代方法。
