前十字带重建 (ACLR) 患者表现出改变的步态生物力学,经过手术的肢体缺陷在24个月内得到改善,但持续的双边缺陷出现. 建议早期和持续地重新训练步态.
科学领域:
- 整形外科 整形外科 整形外科
- 生物力学 生物力学
- 康复科学 康复科学 康复科学
背景情况:
- 双边步态生物力学改变前十字带重建后 (ACLR),可能导致骨关节炎.
- 在ACLR发生后24个月内,双边步态生物力学的纵向变化尚未得到充分研究.
研究的目的:
- 在ACLR后24个月内,与健康的对照组相比,评估双边步态生物力学的纵向变化.
主要方法:
- 一项受控实验室研究包括24名ACLR患者和24名健康对照.
- 3D膝盖步态和地面反应力 (GRF) 在ACLR后3,6,12和24个月收集.
- 线性混合效应模型和双向ANOVA用于统计分析.
主要成果:
- 经过手术的肢体参数 (峰值膝盖伸展角度,峰值膝盖伸展时刻,峰值膝盖曲时刻,垂直地面反应力) 在ACLR后3个月低于对照组.
- 大多数参数在12个月后正常化,但双边赤字在24个月后再次出现.
- 在整个24个月的随访期间,观察到膝盖屈曲时刻的持续双边减少.
结论:
- 步行生物力学在ACLR后显示部分恢复,手术肢体缺陷有所改善,但双边补偿性减少出现并持续存在.
- 推在ACLR后至少24个月进行早期和持续的步行重新训练和神经肌肉控制训练.
