The high prevalence of shoulder-related dysfunction has focused increased attention on functional activity assessment. This study (1) tested the reliability of three-dimensional shoulder complex movements during four functional tasks representing different levels of task difficulty, (2) characterized the four functional tasks, and (3) examined the relationships between age and shoulder movements. Twenty-five asymptomatic subjects, all veterans aged 30-82, performed the four functional tasks. Good within-session reliability was found (movement pattern: similarity index = 0.81 to 0.97, peak values: intraclass correlation coefficients = 0.88 to 0.99). The raising arm to overhead height task (hard task) placed the greatest demand on scapular motions and humeral elevation (p < 0.005). During the functional tasks, significant correlations existed between age and scapular tipping, humeral elevation, and scapular upward rotation (r = -0.62 to 0.50, p < 0.05). Correlation results indicated that elderly subjects have a greater potential for serratus anterior muscle weakness and shoulder capsule tightness.
肩部相关功能障碍的高患病率使得人们对功能活动评估的关注度日益增加。本研究：（1）测试了在代表不同任务难度水平的四项功能任务中三维肩部复合体运动的可靠性；（2）描述了这四项功能任务的特征；（3）研究了年龄与肩部运动之间的关系。25名无症状受试者均为年龄在30 - 82岁之间的退伍军人，他们完成了这四项功能任务。研究发现各任务期间的可靠性良好（运动模式：相似性指数 = 0.81至0.97，峰值：组内相关系数 = 0.88至0.99）。将手臂举过头顶高度的任务（困难任务）对肩胛骨运动和肱骨抬高的要求最高（p < 0.005）。在功能任务期间，年龄与肩胛骨倾斜、肱骨抬高和肩胛骨向上旋转之间存在显著相关性（r = -0.62至0.50，p < 0.05）。相关结果表明，老年受试者存在更大的前锯肌无力和肩关节囊紧张的可能性。
