电磁波照射联合等速离心运动对骨性关节炎患者下肢肌力及膝关节功能的影响

Effect of Electromagnetic Wave Irradiation Combined with Isokinetic Centrifugal Motion on Lower Limb Muscle Strength and Knee Joint Function in Patients with Osteoarthritis

目的:探讨电磁波照射联合等速离心运动对骨性关节炎患者下肢肌力及膝关节功能的影响。方法:选取2021年4月—2022年12月新密市中医院收治的84例骨性关节炎患者作为研究对象。采用随机数表法将其分为对照组和观察组,每组各42例。对照组患者接受等速离心运动干预;观察组患者在对照组基础上加用电磁波照射。两组患者均连续干预4周。对比干预前、干预4周后患者膝关节功能[Lysholm膝关节功能评分、骨关节炎指数评分(WOMAC)]、疼痛程度[视觉模拟评分(VAS)];对比两组患者第一次、最后一次进行等速离心运动时的下肢肌力情况(峰力矩、力矩加速能、单次最大做功量、平均功率)。结果:干预后,两组患者Lysholm膝关节功能评分增加,WOMAC、VAS下降,且观察组患者Lysholm膝关节功能评分高于对照组,WOMAC、VAS低于对照组,差异有统计学意义(t=6.165、7.590、3.910,P<0.05)。干预后,两组患者峰力矩、力矩加速能、单次最大做功量、平均功率值均增加,且观察组高于对照组,差异有统计学意义(t=6.103、2.159、5.826、6.752,P<0.05)。结论:电磁波照射联合等速离心运动可改善骨性关节炎患者的膝关节功能,降低疼痛程度,提高下肢肌力。

Objective:To investigate the effect of electromagnetic wave irradiation combined with isokinetic centrifugal motion on lower limb muscle strength and knee joint function in patients with osteoarthritis.Methods:A prospective randomized controlled study was conducted on 84 patients with osteoarthritis in Xinmi Hospital of TCM from April 2021 to December 2022.They were divided into control group and observation group using a random number table method,with 42 patients in each group.The control group received isokinetic centrifugal motion intervention.The observation group received electromagnetic wave irradiation based on the control group.Both groups were continuously intervened for 4 weeks.The knee joint function(Lysholm,WOMAC and VAS)of patients before and after 4 weeks of intervention were compared.The lower limb muscle strength(peak torque,torque acceleration energy,maximum single effort and average power)of two groups during the first and last isokinetic eccentric exercise were compared.Results:After intervention,the Lysholm knee joint function score of the two groups increased.The WOMAC and VAS scores decreased,and the observation group was lower than the control group,with statistically significant difference(t=6.165,7.590,3.910;P<0.05).After intervention,the peak torque,torque acceleration energy,single maximum work amount and average power values of the two groups increased.The observation group was greater than the control group,with statistically significant difference(t=6.103,2.159,5.826,6.752;P<0.05).Conclusion:Electromagnetic wave irradiation combined with isokinetic centrifugal motion can improve knee joint function,reduce pain level,and improve lower limb muscle strength in patients with osteoarthritis.
