摘要:
      摘要 目的:评估不同水平BFR结合LIRT对KOA患者疼痛、肌肉激活及平衡功能的影响。 方法:将100例KOA患者随机分为LIRT组、LIRT+BFR30%组、LIRT+BFR50%组和LIRT+BFR80%组。LIRT组仅接受30% 1RM的LIRT训练,而LIRT+BFR30%、LIRT+BFR50%和LIRT+BFR80%组分别在动脉闭塞压(AOP)30%、50%和80%时应用BFR进行30% 1RM的LIRT。每组均进行每周3次,共8周的干预。在干预前后评估视觉模拟评分(VAS),股外侧肌、股内侧肌和股直肌均方根振幅(RMS)以及睁眼/闭眼状态下的静态平衡功能。 结果:双向重复测量方差分析显示,VAS(P<0.001,η2p=0.190)、股直肌RMS(P<0.001,η2p=0.259)、股内侧肌RMS(P<0.001,η2p=0.348)、股外侧肌RMS(P<0.001,η2p=0.230)、闭眼运动椭圆面积(P<0.001,η2p=0.183)、睁眼运动长度(P=0.010,η2p=0.111)、闭眼运动长度(P<0.001,η2p=0.260)结果中存在显著的“组别×时间”交互效应。干预后,LIRT+BFR80%组的股直肌RMS、股内侧肌RMS、股外侧肌RMS显著高于LIRT组(P<0.001)、LIRT+BFR30%组(P<0.001)、LIRT+BFR50%组(P<0.05),同时,LIRT+BFR80%组的闭眼运动长度显著低于LIRT组(P<0.001)、LIRT+BFR30%组(P<0.001)、LIRT+BFR50%组(P=0.004),另外,LIRT+BFR80%组的闭眼运动椭圆面积有显著低于LIRT+BFR50%组的趋势(P=0.052)。 结论:在BFR为AOP 80%时进行LIRT可显著缓解KOA患者的疼痛程度,并提高肌肉激活水平和平衡能力。

Abstract:
      Abstract Objective: To evaluate the effects of different levels of blood flow restriction (BFR) combined with low-intensity resistance training(LIRT) on pain, muscle activation, and balance function in patients with knee osteoarthritis(KOA). Method: One hundred patients with KOA were randomly divided into four groups: LIRT group, LIRT+BFR30% group, LIRT+BFR50% group, and LIRT+BFR80% group. The LIRT group received only LIRT at 30% one-repetition maximum (1RM), while the LIRT+BFR30%, LIRT+BFR50%, and LIRT+BFR80% groups performed LIRT at 30% 1RM with BFR applied at 30%, 50%, and 80% of arterial occlusion pressure(AOP), respectively. Each group underwent the intervention three times per week for eight weeks, and assessments were conducted before and after the intervention. The assessment indicators included visual analog scale(VAS), root mean square amplitude (RMS) of the vastus lateralis, vastus medialis, and rectus femoris muscles, as well as static balance function under open-eye/closed-eye conditions. Result: Two-way repeated measures analysis of variance showed significant "group × time" interaction effects of the VAS (P<0.001,η2p=0.190), rectus femoris RMS (P<0.001, η2p=0.259), vastus medialis RMS (P<0.001, η2p=0.348), vastus lateralis RMS (P<0.001, η2p=0.230), closed-eye motion ellipse area (P<0.001, η2p=0.183), open-eye motion length (P=0.010, η2p=0.111), and closed-eye motion length (P<0.001, η2p=0.260). After intervention, the rectus femoris RMS, vastus medialis RMS, and vastus lateralis RMS of the LIRT+BFR80% group were significantly higher than those of the LIRT group (P<0.001), LIRT+BFR30% group (P<0.001), and LIRT+BFR50% group (P<0.05). Meanwhile, the closed-eye motion length of the LIRT+BFR80% group was significantly lower than that of the LIRT group (P<0.001), LIRT+BFR30% group (P<0.001), and LIRT+BFR50% group (P=0.004). In addition, there was a trend for the closed-eye motion ellipse area of the LIRT+BFR80% group to be significantly lower than that of the LIRT+BFR50% group (P=0.052). Conclusion: Performing LIRT with BFR is at 80% of AOP can significantly relieve pain level of KOA patients and improve muscle activation and balance ability in patients with KOA.
