[Purpose] Examination and treatment of the long head of the biceps tendon (LHBT) requires accurate palpation. The purpose of this study was to determine physical therapists' reliability and ability to accurately palpate the LHBT in two arm positions with ultrasound as the gold standard. [Participants and Methods] Examiners palpated the LHBT within the intertubercular groove (ITG) of the humerus on the bilateral shoulders of 32 asymptomatic (21 female; 24.3 ± 1.9 years) participants in 2 arm positions. The magnitude of distance between a marker and the border of the ITG was compared between 2 positions using an independent t-test. Percent accuracy was calculated. [Results] Inter-rater reliability was poor (position 1, =1.04; position 2, =0.016). Overall accuracy rate was 45.7% (117/256). Accuracy was 49.2% (63/128) and 42.2% (54/128) for testing position 1 and position 2 respectively. Mean distance palpated from the groove was =2.58 mm (± 6.2 mm) for position 1 and =3.77 mm (± 6.6 mm) for position 2. Inaccurate palpation occurred medially 72.3% (47/65) and 93.2% (69/74) in position 1 and position 2 respectively. [Conclusion] Results of this study did not support one arm position being more accurate over another for LHBT palpation.
[目的] 肱二头肌长头肌腱（LHBT）的检查和治疗需要精确的触诊。本研究的目的是以超声作为金标准，确定物理治疗师在两种手臂位置准确触诊LHBT的可靠性和能力。[参与者与方法] 检查者在32名无症状参与者（21名女性；24.3±1.9岁）的双侧肩部，于肱骨结节间沟（ITG）内触诊LHBT，共两种手臂位置。使用独立t检验比较两个位置之间标志物与ITG边界的距离大小。计算准确率。[结果] 评分者间信度较差（位置1，=1.04；位置2，=0.016）。总体准确率为45.7%（117/256）。测试位置1和位置2的准确率分别为49.2%（63/128）和42.2%（54/128）。位置1从沟处触诊的平均距离为=2.58 mm（±6.2 mm），位置2为=3.77 mm（±6.6 mm）。位置1和位置2触诊不准确分别有72.3%（47/65）和93.2%（69/74）发生在内侧。[结论] 本研究结果不支持在LHBT触诊中一种手臂位置比另一种更准确。
