年龄会影响肩关节的总体活动范围（ROM），但一生中的生物力学变化通常仅表现为肩胸关节的特征。为了进一步了解肩关节损伤和病理学，需要肩胛胸和盂肱对肱骨胸运动的贡献的合适的年龄相关基线。值得注意的是，年轻或老年人群之间的生物力学比较可能会掩盖潜在肩部运动的差异。在此，双平面荧光透视和皮肤标记运动分析量化了3种静态姿势（静止中立、内旋至L4-L5和内旋至最大伸展）和2种动态活动（肩胛平面外展和内收时外旋）期间的肱骨、肩胛胸和盂肱运动。在45岁的受试者（每组N = 10例受试者）之间比较静态姿势期间的定向和主动ROM期间的旋转。<35 years and >测量了许多与年龄相关的运动学差异，范围为5 - 25 °，其中一致观察到肩胛骨方向和运动的变化。这些差异等于或超过临床ROM的平均临床重要差异和测量标准误，这表明需要高分辨率技术和适当匹配的对照，以避免混淆研究肩关节运动学的研究结果。了解这些差异将有助于临床医生管理的期望和治疗方案的适应症和患病率之间的年龄组往往不同。在可能的情况下，建议在研究肩关节损伤的运动学、病理学或手术/物理治疗干预时选择年龄匹配的对照队列，以确保不忽视临床上重要的差异。
Age affects gross shoulder range of motion (ROM), but biomechanical changes over a lifetime are typically only characterized for the humerothoracic joint. Suitable age-related baselines for the scapulothoracic and glenohumeral contributions to humerothoracic motion are needed to advance understanding of shoulder injuries and pathology. Notably, biomechanical comparisons between younger or older populations may obscure detected differences in underlying shoulder motion. Herein, biplane fluoroscopy and skin-marker motion analysis quantified humerothoracic, scapulothoracic, and glenohumeral motion during 3 static poses (resting neutral, internal rotation to L4-L5, and internal rotation to maximum reach) and 2 dynamic activities (scapular plane abduction and external rotation in adduction). Orientations during static poses and rotations during active ROM were compared between subjects <35 years and >45 years of age (N=10 subjects per group). Numerous age-related kinematic differences were measured, ranging 5–25°, where variations in scapular orientation and motion were consistently observed. These disparities are on par with or exceed mean clinically important differences and standard error of measurement of clinical ROM, which indicates that high resolution techniques and appropriately matched controls are required to avoid confounding results of studies that investigate shoulder kinematics. Understanding these dissimilarities will help clinicians manage expectations and treatment protocols where indications and prevalence between age groups tend to differ. Where possible, it is advised to select age-matched control cohorts when studying the kinematics of shoulder injury, pathology, or surgical/physical therapy interventions to ensure clinically important differences are not overlooked.
