| 目的：探讨血流限制肌力训练（BFRT）和常规肌力训练对股四头肌形态及等速伸膝肌力恢复的短期疗效，以及不同性别使用血流限制训练是否存在差异。方法：将50例膝关节镜术后患者随机分成对照组和BFRT组，每组各25例，2组均进行常规康复治疗，以及使用蹬踏推举设备进行下肢力量训练，其中BFRT组在蹬踏训练中使用血流限制训练方法，持续4周。治疗前和治疗后4周进行疗效评估，采用肌骨超声评定术侧下肢股直肌厚度、股直肌横截面积、股中间肌厚度等指标，采用等速评估设备测量伸膝峰力矩与体重比，采用卷尺测量髌骨上缘上10cm肌围度。结果：治疗4周后，BFRT组患者治疗后股直肌厚度、股直肌横截面积及股中间肌厚度均较治疗前显著增加（P<0.01）；2组患者伸膝峰力矩与体重比均较治疗前显著增加（P<0.01），组间差异无统计学意义。在膝峰力矩与体重比的训练前后变化中，训练方式与性别存在联合调节效应（P<0.01）。BFRT组患者治疗后肌围度较治疗前显著增加（P<0.01）。结论：BFRT与常规肌力训练均能增加膝关节镜术后伸膝峰力矩与体重比，女性使用BFRT增加肌力效果优于男性，BFRT可以增加患者超声下股四头肌形态及肌肉围度。 |

| Objective: To investigate the short-term efficacy of blood flow restriction training (BFRT) versus conventional resistance training for the recovery of quadriceps morphology and isokinetic knee extension strength, and to explore potential sex-related differences in the efficacy of BFRT. Methods: A total of 50 patients who had under-gone knee arthroscopy were randomly allocated to a control group (n=25) or a BFRT group (n=25). Both groups followed an identical standard rehabilitation program that included lower-limb strength training on a leg-press device for 4 weeks. The BFRT group performed the leg-press exercises with blood-flow restriction. Outcomes were assessed before and 4 weeks after treatment. Musculoskeletal ultrasound was used to measure the thickness of the rectus femoris, cross-sectional area (CSA) of the rectus femoris, and thickness of the vastus intermedius of the operative limb. An isokinetic dynamometer was used to record peak knee-extension torque normalized to body weight, and a tape measure was used to determine mid-thigh circumference 10 cm above the superior pole of the patella. Results: After 4 weeks, the BFRT group showed significant post-treatment increases in rectus femoris thickness, rectus femoris CSA, and vastus intermedius thickness (all P<0.01). Both groups exhibited significant increases in peak knee-extension torque normalized to body weight (P<0.01), with no statistically significant difference between the two groups in this outcome. A significant interaction effect between training modality and sex was observed for changes in peak knee-extension torque normalized to body weight (P<0.01). Mid-thigh circumference (10 cm above the superior pole of the patella) also increased significantly in the BFRT group (P<0.01). Conclusion: Both BFRT and conventional strength training improved the peak knee-extension torque-to-body weight ratio after knee arthroscopy. BFRT demonstrated superior effects on muscle strength in female participants compared with male participants. Furthermore, BFRT improved ultrasound-assessed quadriceps morphology and increased muscle circumference. |
