本研究的主要目的是建立基于灰度的定量超声（QUS）测量肱二头肌和冈上肌肌腱的有效性。从67名轮椅使用者的超声图像中计算了肱二头肌和冈上肌的9个QUS测量值。采用问卷调查、体格检查和临床超声分级量表来测量肩部病理。年龄、轮椅使用时间和体重的增加与肌腱颜色更深、更均匀相关。体格检查二头肌压痛和肩锁关节压痛时疼痛的受试者表现出显著不同的冈上肌QUS值。即使在控制肌腱深度的情况下，肱二头肌肌腱的QUS测量结果在健康肌腱、轻度肌腱病和严重肌腱病的受试者之间也存在显著差异。冈上肌腱健康的临床分级与QUS测量的冈上肌腱相关。定量超声是量化肌腱病变的有效方法，可以允许早期发现肌腱病。手动轮椅使用者发生肩腱病变的风险很高，基于定量超声的研究可能会受益，该研究侧重于确定旨在降低这种风险的干预措施。
The primary aim of this study is to establish the validity of greyscale-based quantitative ultrasound (QUS) measures of the biceps and supraspinatus tendons. Nine QUS measures of the biceps and supraspinatus tendons were computed from ultrasound images collected from sixty-seven manual wheelchair users. Shoulder pathology was measured using questionnaires, physical examination maneuvers, and a clinical ultrasound grading scale. Increased age, duration of wheelchair use, and body mass correlated with a darker, more homogenous tendon appearance. Subjects with pain during physical examination tests for biceps tenderness and acromioclavicular joint tenderness exhibited significantly different supraspinatus QUS values. Even when controlling for tendon depth, QUS measures of the biceps tendon differed significantly between subjects with healthy tendons, mild tendinosis, and severe tendinosis. Clinical grading of supraspinatus tendon health was correlated with QUS measures of the supraspinatus tendon. Quantitative ultrasound is valid method to quantify tendinopathy and may allow for early detection of tendinosis. Manual wheelchair users are at a high risk for developing shoulder tendon pathology and may benefit from quantitative ultrasound-based research that focuses on identifying interventions designed to reduce this risk.
