等速肌力测试评价断裂跟腱修复后的肌肉力量

Isokinetic muscle strength test for the muscular force after repair of ruptured Achilles tendon

背景:恢复跟腱的完整性和坚韧性以及踝关节的灵活性对跟腱断裂的结局尤为重要。目的:实验采用等速肌力测试系统测试跟腱断裂修复后的肌肉力量,评价其修复效果。方法:采用Biodex System 4多关节等速肌力测试系统,以60(°)/s,120(°)/s两种速度测定17例跟腱断裂修复后三四个月患者的屈踝和伸踝肌力,指标包括峰力矩、峰力矩/体质量比值、总功、平均峰力矩和单次最大功。结果与结论:断裂跟腱修复后患者患侧屈肌群的峰力矩、峰力矩/体质量比、总功、平均峰力矩和单次最大功5项检测指标在60(°)/s和120(°)/s时较健侧均显著降低(P<0.05)。结果证实,等速肌力测试可有效反映跟腱断裂修复后的肌肉力量情况,能评价跟腱断裂修复后的效果。

BACKGROUND：Restoration of tendon integrity and tenacity, and maintenance of ankle joint flexibility, play a crucial role on the rupture of Achiles tendon. OBJECTIVE： To evaluate the muscular force using isokinetic muscle strength test after the ruptured Achiles tendon is repaired, and to assess the repairing effect. METHODS： Muscle power including peak torque, peak torque/body weight, total work, average peak torque, set total work of flexor and extensor of 17 patients with Achiles tendon rupture were assessed after reconstruction using Biodex system 4 at 60 （°）/s and 120（°）/s. RESULTS AND CONCLUSION：The peak torque, peak torque/body weight, total work, average peak torque, set total work of flexor muscle group at the injured side were significantly decreased compared with uninjured side at 60 （°）/s and 120 （°）/s （P 〈 0.05）. Isokinetic muscle strength test can reflect the muscular force after the ruptured Achiles tendon is repaired, and evaluate the repairing effect.
