肌电生物反馈联合抗阻训练对老年骨关节炎患者膝关节功能的影响

Effect of Myoelectric Biofeedback Combined with Resistance Training on Knee Joint Function in Elderly Patients with Osteoarthritis

目的:探讨肌电生物反馈联合抗阻训练对老年骨关节炎患者膝关节功能的影响。方法:选取2020年1月—2023年1月九江市第一人民医院收治的老年骨关节炎患者102例,随机分为两组,其中对照组(n=51)采用抗阻训练治疗,观察组(n=51)在对照组基础上联合肌电生物反馈治疗,比较两组临床疗效、疼痛评分、膝关节功能及等速肌力参数水平。结果:观察组总有效率为90.20%,高于对照组的74.51%,差异有统计学意义(P<0.05)。干预8周,观察组视觉模拟评分法(VAS)评分、改良版西安大略和麦克马斯特大学骨关节炎指数(WOMAC)评分均低于对照组,Lysholm膝关节评分量表(LKSS)评分高于对照组,差异均有统计学意义(P<0.05)。干预8周,观察组等速肌力参数峰力矩(PT)、总做功量(TW)、疲劳指数(WF)水平均高于对照组,差异均有统计学意义(P<0.05)。结论:老年骨关节炎患者采用肌电生物反馈联合抗阻训练疗效显著,能有效减轻患膝疼痛程度,改善膝关节屈伸肌力及活动功能。

Objective:To investigate the effect of myoelectric biofeedback combined with resistance training on knee joint function in elderly patients with osteoarthritis.Method:A total of 102 elderly patients with osteoarthritis admitted to Jiujiang NO.1 People's Hospital from January 2020 to January 2023 were selected and randomly divided into two groups.The control group(n=51)received resistance training treatment,and the observation group(n=51)combined with myoelectric biofeedback treatment.The clinical efficacy,pain score,knee joint function and isokinetic muscle strength parameters of the two groups were compared.Result:The total effective rate of observation group was 90.20%,which was higher than 74.51%of control group,the difference was statistically significant(P<0.05).8 weeks of intervention,the visual analogue scale(VAS)score and the modified Western Ontario and McMaster University osteoarthritis index(WOMAC)score in the observation group were lower than those in the control group,and the Lysholm knee joint score scale(LKSS)score was higher than that in the control group,the differences were statistically significant(P<0.05).8 weeks of intervention,isokinetic muscle force parameters peak moment(PT),total work done(TW)and work fatigue(WF)in observation group were higher than those in control group,the differences were statistically significant(P<0.05).Conclusion:The effect of myoelectric biofeedback combined with resistance training in elderly patients with osteoarthritis is significant,which can effectively reduce the degree of knee pain,improve knee flexion and extension muscle strength and activity function.
