肌电生物反馈配合抗阻训练对老年膝骨关节炎患者康复的影响

Effect of electromyographic biofeedback complicated with resistance training on rehabilitation of elderly patients with knee osteoarthritis

目的分析对老年膝骨关节炎(KOA)患者采用肌电生物反馈配合抗阻训练的效果。方法选取2019年7月至2021年1月四川大学华西医院收治的100例老年KOA患者作为研究对象,采用随机数字表法将其分为观察组与对照组,各50例。对照组采用常规康复治疗和抗阻训练,观察组采用常规康复治疗和肌电生物反馈配合抗阻训练,两组均连续干预21 d。评估两组干预前后的视觉模拟评分法(VAS)、西安大略和麦克马斯特大学(WOMAC)骨关节炎指数量表、Lysholm膝关节评分及等速肌力参数[峰力矩(PT)、总做功量(TW)、疲劳指数(WF)]。统计两组干预期间不良事件发生情况。结果干预后,两组Lysholm膝关节评分均高于干预前,且观察组高于对照组(P<0.05)。干预后,两组VAS、WOMAC骨关节炎指数量表评分均低于干预前,且观察组低于对照组(P<0.05)。干预后,两组伸膝PT、TW、WF均高于干预前,且观察组高于对照组(P<0.05)。两组干预期间不良事件总发生率比较,差异无统计学意义(P>0.05)。结论老年KOA患者采用肌电生物反馈配合抗阻训练可有效减轻疼痛程度,增强抗疲劳能力,改善膝关节功能,值得临床推广。

Objective To analyze the effect of electromyographic biofeedback complicated with resistance training in elderly patients with knee osteoarthritis(KOA).Methods A total of 100 elderly patients with KOA admitted to West China Hospital,Sichuan University from July 2019 to January 2021 were selected as the research subjects.They were divided into observation group and control group by random number table method,with 50 cases in each group.The control group received routine rehabilitation therapy and resistance training,and the observation group received routine rehabilitation therapy and electromyographic biofeedback combined with resistance training.The intervention lasted for 21 days.Visual analog scale(VAS),Western Ontario and McMaster University(WOMAC)osteoarthritis index scale,Lysholm knee score,and isokinetic muscle force parameters(peak moment[PT],total work[TW],work fatigue[WF])were assessed before and after intervention.The incidence of adverse events in the two groups during intervention was analyzed.Results After intervention,Lysholm knee score in both groups was higher than before intervention,and the observation group was higher than the control group(P<0.05).After intervention,VAS and WOMAC osteoarthritis index scale scores of the two groups were lower than before intervention,and the observation group was lower than the control group(P<0.05).After intervention,PT,TW,and WF of knee extension in both groups were higher than before intervention,and the observation group was higher than the control group(P<0.05).There was no significant difference in the total incidence of adverse events between the two groups(P>0.05).Conclusion Electromyographic biofeedback combined with resistance training in elderly patients with KOA can effectively reduce pain,enhance anti-fatigue ability,and improve knee function,which is worthy of clinical promotion.
