概括
手术前的血流限制阻力训练 (BFR-RT) 没有改善膝关节全关节整形术 (TKA) 后的身体功能或患者的结果. 然而,BFR-RT确实在手术后三个月提高了下肢肌肉力量,与通常的护理相比.
科学领域:
- 整形外科 整形外科 整形外科
- 康复医学 康复医学 康复医学
- 运动医学 运动医学
背景情况:
- 骨关节炎 (OA) 是导致膝盖疼痛和残疾的主要原因.
- 全膝关节整形术 (TKA) 是一种常见的手术干预,用于晚期膝关节OA.
- 优化手术前的身体条件对于TKA结果至关重要.
研究的目的:
- 评估8周的手术前低负荷血流限制阻力训练 (BFR-RT) 对身体功能,下肢力量和患者报告结果的影响.
- 为了将BFR-RT与接受TKA的患者的通常手术前护理进行比较.
- 评估TKA后3个月和12个月的结果.
主要方法:
- 评估者盲目的随机对照试验 (RCT) 涉及86名预定接受TKA的患者.
- 干预组:在受影响的腿部进行8周的BFR-RT (3次/周).
- 控制组:通常的手术前护理 (没有运动).
- 主要结果:30秒的坐到站 (30STS).
- 二级结局包括强度测量 (1RM,MVIC),功能测试 (TUG,40mWT) 和患者报告的结局 (KOOS,EQ-5D-L5).
主要成果:
- 在TKA后3个月或12个月,在30STS,定时上行 (TUG) 或40米步行测试 (40mWT) 中,群体之间没有显著差异.
- 显著的改善有利于BFR-RT在1次重复最大 (1RM) 腿部按压,1RM膝盖延伸器强度和TKA后3个月的最大同位数收缩 (MVIC) 膝盖延伸器,但在12个月后没有.
- 在任何时间点,两组之间膝盖运动范围 (ROM),膝盖损伤和骨关节炎结局得分 (KOOS) 或Euroqol 5维 (EQ-5D-L5) 没有显著差异.
结论:
- 在术前的BFR-RT并没有为TKA患者的术后身体功能或患者报告的结果提供比通常护理更好的好处.
- 在TKA后3个月内,BFR-RT显示下肢肌肉强度的短期增长.
- 进一步的研究可能会探索最佳的BFR-RT协议或对TKA的患者选择.
