| 摘 要： | 目的 观察非周期大强度运动训练和推拿对兔膝关节髌韧带生物力学特性的影响。方法 利用非周期大强度运动的动物训练模型造成关节韧带松驰，在训练的同时予以推拿手法恢复。结果 髌韧带生物力学测试发现运动训练可以明显引起韧带应力松驰加快，应力一应变关系右移，弹性系数降低，应变加大；而训练同时予以推拿恢复手段可明显恢复韧带的松驰。结论 非周期大强度运动训练可造成韧带松驰，推拿恢复手段可明显防止韧带的松驰。

| Abstract: | Objective The purpose of this paper was to investigate the effects of acyclic exercise and manipulation on the biomechanical properties of patellar ligament of rabbits. Methods The rabbits underwent acyclic exercise for 3 weeks by an electric cage method and received the manipulations to the rear limbs at the same periods.Results Acyclic exercise increases the velocity of stress relaxation, reduces the elastic modulus of rabbit patellar ligament. In addition, the strain in stress-strain curve shifted to right. The manipulation had a beneficial effect for recovery of these biomechanical behaviors. Conclusion The acyclic exercise induces the relaxation of ligament and the manipulation can prevent it. |
