Study Design. An in vivo rat-tail model was used to study the effects of static compression with different loading magnitudes and durations on the intervertebral disc.
研究设计：使用一种活体大鼠的尾部模型，来研究不同强度和持续时间的静态压力对椎间盘的影响。
The results showed that the static stiffness from theoretical model is more suitable for small compression deformation.
研究表明，当压缩量较小时，理论模型对空气垫静态刚度的预测较为准确。
