| 目的：探索血流量限制结合低强度抗阻训练对下肢骨科术后肌肉功能的影响。方法：选取下肢骨科术后4～12周患者39例，随机将患者分为观察组19例和对照组20例。2组患者均接受为期4周的康复训练，对照组根据渐进抗阻原则进行肌力训练，观察组使用血流量限制结合低强度抗阻肌力训练。等速伸膝峰力矩、超声下股四头肌肌肉形态、肢体围度、静态稳定极限用于评估治疗前后患者的肌肉力量、肌肉形态、运动功能。结果：治疗4周后，2组患者伸膝峰力矩、股直肌厚度及横截面积、静态稳定极限、肢体围度均较治疗前明显提高（P<0.05），且治疗后观察组患者伸膝峰力矩显著优于对照组（P<0.01）；仅观察组患者股中间肌厚度较治疗前有明显增加（P<0.05），2组患者静态稳定极限及肢体围度治疗后比较差异无统计学意义。结论：血流限制性运动结合低强度抗阻肌力训练有助于下肢术后患者肌肉功能，且增加肌肉力量及大小效果优于常规训练。 |

| Objective: To observe the effect of blood flow restriction combined with low-intensity resistance training on muscle function after lower limb orthopedic surgery. Methods: A total of 40 patients undergoing lower limb orthopedic operation within 4-12 weeks were selected, and randomly divided into treatment group (n=19, 1 dropout) and control group (n=20). Patients in both groups received 4 weeks of rehabilitation training. Patients in control group was given general resistant muscle strength training based on the principle of progressive resistance, and those in treatment group were subjected to blood flow restriction combined with low-intensity resistance muscle training. The isokinetic knee extensor peak torque (PT), quadriceps muscle morphology under ultrasound, limb circumference, static stability limit before and after treatment were used to evaluate the muscle strength, muscle shape, and motor function of patients. Results: Patients in the treatment group and the control group were significantly improved in PT, the thickness of the rectus femoris, the cross-sectional area of the rectus femoris, static stability limit, and limb circumference after treatment as compared with those before treatment (P<0.05). The improvement of PT in the treatment group was significantly better than that in the control group (P<0.001). The thickness of the vastus intermedius in the treatment group was significantly improved as compared with that before treatment (P<0.05). Conclusion: Blood flow restrictive exercise combined with low-intensity resistance training can improve the muscle function of patients after lower limb surgery, and the effect of increasing muscle mass and muscle strotu are better than conventional training. |
