背景调查的协调肱骨，肩胛骨和胸腰椎脊柱运动在一定范围内的运动conditions.Methods的单侧和双侧上肢运动的32名健康女性进行单侧和双侧手臂抬高在三个平面，矢状面，冠状面和肩胛骨。使用多传感器、6自由度电磁跟踪系统在100 Hz下测量肩胛骨、肱骨和脊柱方向。根据国际生物力学学会的研究结果计算节段位移。肱骨、肩胛骨和胸段表现出一致的同步相互作用。肩胛骨向上旋转是显着更大的非优势侧比优势在所有平面的运动，在单侧和双侧手臂运动。单侧和双侧手臂运动产生显著不同的脊柱运动范围和模式以及肩胛骨外旋范围。年龄、身高或体重对上臂抬高时肩胛带和脊柱的运动范围或运动模式似乎没有任何影响。手臂向上运动，无论运动平面如何，对肩带和胸椎都有重要意义。肩关节的临床评估应包括胸椎。(C)2007爱思唯尔有限公司保留所有权利。
Background. To investigate the coordination of humeral, scapular and thoracolumbar spine motions during a number of unilateral and bilateral upper limb movements in a range of movement conditions.Methods Thirty-two healthy women performed unilateral and bilateral arm elevations in three planes-sagittal, coronal and scapular. Scapular, humeral and spinal orientations were measured at 100 Hz using a multi-sensor, 6-degree-of-freedom electromagnetic tracking system. Segmental displacements were computed following International Society of Biomechanics recommendations.Findings. Humeral, scapular and thoracic segments demonstrate consistent, synchronous interactions. Scapular upward rotation is significantly greater on the non-dominant side than the dominant in all planes of movement and in both unilateral and bilateral arm movement. Unilateral and bilateral arm movements produce significantly different ranges and patterns of spinal motion and ranges of scapular external rotation. There does not appear to be any effect of age, height or weight on the ranges or patterns of motion of the shoulder girdle and spine during arm elevation.Interpretation. Movement of the arm into elevation, irrespective of the plane of motion, has significant implications for the shoulder girdle and the thoracic spine. Clinical assessment of the shoulder should include the thoracic spine. (C) 2007 Elsevier Ltd. All rights reserved.
