| 目的 探讨血流限制(BFR)训练联合常规功能训练对前交叉韧带重建(ACLR)术后患者膝关节功能及平衡能力的影响。 方法 采用随机数字表法将29例ACLR术后患者分为观察组(共15例)及对照组(共14例)。2组患者均给予30 min常规功能训练，在此基础上观察组患者辅以BFR训练，对照组则同期辅以假BFR训练（即训练过程中BFR设备不加压），2组患者均每周治疗3次，连续治疗8周。于治疗前、治疗2周及治疗8周后分别对2组患者膝关节功能、股四头肌肌力及静态平衡能力进行评定。 结果 治疗2周、8周后观察组患者Lysholm膝关节评分［分别为（58.20±3.97）分和（89.87±2.72）分］、股四头肌峰力矩（PT）［分别为（55.13±7.92）N·m和（80.87±12.65）N·m］、峰力矩体重百分比（PT/BW）［分别为（81.80±5.83）%和（119.73±8.24）%］、睁眼时足底压力中心椭圆面积（AR）［分别为（130.07±13.46）mm2和（85.13±17.36）mm2］、足底压力中心（centre of pressure, COP）移动速度［分别为（12.40±0.98）mm/s和（8.69±0.99）mm/s］、闭眼时AR ［分别为（208.33±18.60）mm2和（156.07±10.09）mm2］、闭眼时COP移动速度［分别为（15.01±0.94）mm/s和（12.05±0.99）mm/s］均显著优于治疗前水平（P<0.05），治疗8周后观察组上述各项指标结果亦显著优于同期对照组水平（P＜0.05）。 结论 BFR训练联合常规功能训练能进一步增强ACLR术后患者股四头肌肌力，改善膝关节功能及静态平衡能力，该联合疗法值得临床推广、应用。 |

| Objective To test the effect of combining blood flow restriction(BFR) with conventional functional training in rehabilitation following anterior cruciate ligament reconstruction(ACLR). Methods Twenty-nine post-ACLR patients were randomly assigned to an observation group(n=15) or a control group(n=14). Both groups received 30 minutes of conventional functional training daily. The observation group also received BFR, while the control group received sham BFR(cuffs applied without pressure). The interventions were administered three times per week for 8 consecutive weeks. Knee function, quadriceps strength and static balance were measured at baseline and after 2 and 8 weeks. Results At 2 and 8 weeks, the observation group demonstrated significant improvements in its average Lysholm knee score(from 58.20±3.97 to 89.87±2.72), quadriceps peak torque(PT)(from 55.13±7.92 to 80.87±12.65Nm), and peak torque to body weight percentage(PT/BW)(from 81.80±5.83% to 119.73±8.24%). Significant improvements in static balance were also observed. The average 95% confidence ellipse area for the center of pressure and the average center of pressure velocity with the eyes both open and closed had all improved significantly. At the 8-weeks mark, all of the observation group′s outcome measures were significantly superior to those of the control group. Conclusions Combining BFR training with conventional functional training effectively enhances quadriceps strength, knee joint function, and static balance after ACLR. This combined therapy warrants clinical promotion. |
