The rotator cuff is loaded under static as well as dynamic conditions. Whilst the static properties of the rotator cuff muscle-tendon junctions have been reported, the dynamic mechanical behaviour has not. This study reports the dynamic mechanical properties with varying abduction angles in a human cadaver rotator cuff. No significant effect was found with varying the angle of testing or in the presence of a tear in the tendon. The supraspinatus was found to be the stiffest of the rotator cuff tendons followed by the subscapularis and infraspinatus.
肩袖在静态和动态条件下均承受负荷。虽然已有关于肩袖肌腱-肌肉连接处静态特性的报道，但动态力学行为尚未见报道。本研究报告了人体尸体肩袖在不同外展角度下的动态力学特性。研究发现，测试角度的变化或肌腱存在撕裂对结果均无显著影响。结果显示，冈上肌是肩袖肌腱中最僵硬的，其次是肩胛下肌和冈下肌。
