Clinical efficacy of electroacupuncture combined with blood flow restriction training for knee osteoarthritis and how to impact on pain swelling and functional recovery

目的观察电针联合血流限制训练(BFRT)治疗膝骨关节炎(KOA)的临床疗效及对患者疼痛肿胀和功能恢复的影响。方法选取2019年6月至2021年6月江苏省盐城市大丰中医院针灸康复科KOA门诊患者104例,按照随机数字表法分为观察组52例和对照组52例。对照组给予电针治疗,观察组给予电针联合BFRT治疗,2组均治疗3个月。采用视觉模拟评分(VAS)评价2组患者活动关节舒适度,Lysholm下肢关节功能评分评价下肢关节运动功能,测试2组患者伸膝最大角度及屈膝最大角度,并测量2组标准伸膝肌力,比较2组疗效以及治疗期间并发症发生情况。结果治疗后2组膝关节活动度比较,观察组伸膝最大角度、屈膝最大角度均大于对照组(P<0.05)。治疗后2组活动关节舒适度VAS与本组治疗前比较明显下降,Lysholm下肢关节功能评分与本组治疗前比较明显升高,且观察组治疗后活动关节舒适度VAS低于对照组,Lysholm下肢关节功能评分高于对照组(P<0.05)。治疗后2组标准伸膝肌力比较,观察组大于对照组(P<0.05)。观察组有效率为94.23%(49/52),对照组78.85%(41/52),观察组疗效优于对照组(P<0.05)。观察组并发症发生率3.85%(2/52),对照组15.38%(8/52),观察组低于对照组(P<0.05)。结论KOA患者采用电针联合BFRT康复治疗,有利于减轻患者关节疼痛及肿胀,增加膝关节活动度,并促进关节功能恢复,效果显著,安全可靠。

Objective To observe the clinical efficacy of electroacupuncture combined with blood flow restriction training(BFRT)for knee osteoarthritis(KOA)and how to impact on pain swelling and functional recovery.Methods From June 2019 to June 2021,a total of 104 KOA outpatients admitted to the Department of Acupuncture and Rehabilitation,Yancheng Dafeng Hospital of Traditional Chinese Medicine were randomly divided into the observation group(n=52)and the control group(n=52).The observation group was treated with electroacupuncture combined with BFRT,the control group with electroacupuncture only.A 3-month treatment was performed;the visual analogue scale(VAS)was used to evaluate the comfortable degree of joint activities;lower limb joint motion function was evaluated using Lysholm lower limb joint function score;maximum angle of knee joint extension and flexion,and knee extensor strength was measured.The curative effect and complication were assessed.Results In the comparison of the knee joint mobility,maximum angle of knee joint extension and flexion was increased in the observation group compared with the control group(P<0.05).After treatment,VAS for comfortable degree of joint activities in groups was decreased,the observation group was more common(P<0.05);Lysholm lower limb joint function scores in groups were increased,the observation group was more prevalent(P<0.05);standard knee extensor muscle strength in the observation group was higher than that in the control group(P<0.05).The overall effective rate in observation group was better than that in control group(94.23%[49/52]vs 78.85%[41/52],[P<0.05],respectively).The postoperative morbidity was 3.85%(2/52)in the observation group,lower than that of 15.38%(8/52)in the control group(P<0.05).Conclusion For KOA patients,electroacupuncture combined with BFRT is conducive to reduce joint pain and swelling,increase knee joint mobility and promote joint function recovery,with remarkable effect,safety and reliability.
