背景资料。肩部运动过程中的肩胛骨活动对于正常的肩部功能至关重要。随着年龄的增长，几乎所有人的肌肉功能都会恶化，这可能会导致肩部撞击综合征。44名正常人参加了这项研究，其中23名男性和21名女性年龄在16岁到73岁之间，平均年龄为48岁。分别拍摄外展0度和90度的静态前后位X线片，用皮尔逊相关系数检验年龄与肩胛骨方向的相关性。本研究的目的是探讨年龄与肩-胸方向的关系。年龄和肩胛骨方向之间存在显著的相关关系。肩关节外展0度时，后倾角与年龄呈显著负相关。外展90度时，后倾角和向上旋转角均与年龄呈负相关。这种相关性在90度外展时很明显。结果表明，肩关节的老化与肩胛骨方向的改变密切相关，主要表现为外展0度和90度时肩关节后倾角减小，90度时肩关节向上旋转角度减小。目前的研究表明，衰老对肩部的影响之一是后倾角和向上旋转角的减少，如外展姿势所见；这些变化类似于肩部撞击综合征的肩关节运动学。通过考虑这一概念，可以适当地评估老化对肩部运动学的影响。(C)2004爱思唯尔有限公司。保留所有权利。
Background. Scapular activity during shoulder motion is critical for normal shoulder function. With aging, muscle function deteriorates in almost all people, which may lead to shoulder impingement syndrome.Methods. Forty-four normal subjects, 23 men and 21 women aged front 16 to 73 years with a mean age 48, were enrolled in the study. Static antero-posterior radiography at both 0degrees and 90degrees of abduction were undertaken and correlation between age and scapular orientations were evaluated by Pearson's correlation coefficient test. The purpose of this study is to investigate the relationship between aging and scapulo-thoracic orientation.Findings. Significant correlation coefficients were observed between aging and scapular orientations. With the shoulder at 0degrees abduction, posterior tilt showed significant negative correlation with aging. At 90degrees abduction, both posterior tilt and upward rotation angle correlated negatively with aging. The correlation was apparent at 90degrees abduction.Interpretation. The results indicate that shoulder aging closely relates to changes of scapular orientation, which consist of decreases of the posterior tilt at 0degrees and 90degrees abduction and the upward rotation angle at 90degrees. The current study indicated that one of the effects of aging on the shoulder is a decrease of posterior tilt and upward rotation angle as seen in an abducted position; and that these alterations are similar to the scapular kinematics of shoulder impingement syndrome. By taking this concept into consideration, the effects of aging on shoulder kinematics can be appropriately evaluated. (C) 2004 Elsevier Ltd. All rights reserved.
