核心肌群渐进式训练联合中频理疗在老年膝骨关节炎患者中的应用效果

Application effects of core muscle group progressive training combined with medium frequency physiotherapy in elderly patients with knee osteoarthritis

目的:观察核心肌群渐进式训练联合中频理疗在老年膝骨关节炎患者中的应用效果。方法:选取2021年3月至2023年2月该院收治的90例膝骨关节炎患者进行前瞻性研究,按随机数字表法将其分为对照组(n=45)与观察组(n=45)。对照组予以中频理疗,观察组在对照组基础上联合核心肌群渐进式训练。比较两组干预前后疼痛程度[视觉模拟评分法(VAS)]评分、膝关节功能[Lysholm膝关节功能、美国特种外科医院(HSS)]评分和股四头肌肌力[股四头肌表面积分肌电值(iEMG)、中位频率(MF)]水平。结果:干预4、8周后,两组VAS评分均低于干预前,且观察组低于对照组,差异有统计学意义(P<0.05);两组Lysholm、HSS评分均高于干预前,且观察组高于对照组,差异有统计学意义(P<0.05);两组股四头肌iEMG、MF水平均高于干预前,且观察组高于对照组,差异有统计学意义(P<0.05)。结论:核心肌群渐进式训练联合中频理疗应用于老年膝骨关节炎患者可提高膝关节功能评分和股四头肌肌力水平,降低疼痛程度评分,其效果优于单纯中频理疗。

Objective:To observe application effects of core muscle group progressive training combined with medium frequency physiotherapy in elderly patients with knee osteoarthritis.Methods:A prospective study was conducted on 90 patients with knee osteoarthritis admitted to the hospital from March 2021 to February 2023.According to the random number table method,they were divided into control group(n=45)and observation group(n=45).The control group was given medium frequency physiotherapy,while the observation group was combined with the core muscle group progressive training on the basis of that of the control group.The pain degree[visual analogue scale(VAS)]score,the knee function[Lysholm knee function,American Hospital for Special Surgery(HSS)]score,and the quadriceps femoris muscle strength[quadriceps femoris surface integral electromyography(iEMG),median frequency(MF)]were compared between the two group before and after the intervention.Results:After 4 and 8 weeks of intervention,the VAS scores of the two groups were lower than those before the intervention,those in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).The Lysholm and HSS scores of the two groups were higher than those before the intervention,those in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).Further,the levels of iEMG and MF of quadriceps femoris in the two groups were higher than those before the intervention,those in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).Conclusions:The core muscle group progressive training combined with the medium frequency physiotherapy in the elderly patients with knee osteoarthritis can improve the knee joint function scores and the quadriceps femoris muscle strength levels,and reduce the pain scores.Moreover,it is superior to single medium frequency physiotherapy.
