Abstract:
Objective To investigate the effect of manual therapy based on surface electromyography on knee osteoarthritis(KOA)in the older people. Methods A total of 106 outpatient with unilateral KOA were selected from Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine,from August,2023 to June,2024,and were randomly divided into control group(n=53)and experimental group(n=53).The control group accepted routine manual therapy,and the experimental group accepted manual therapy based on the analysis of average electromyography(AEMG).They were assessed with Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC),Visual An-alogue Scale(VAS)for pain,Tinetti Balance and Gait Score,and 6-minute walk test(6-MWT)distances before and after treatment. Results One case dropped down in each group.Before treatment,AEMG decreased in the rectus femoris,medial femoris and medial head of gastrocnemius on the affected side in the experimental group(|Z|>8.647,P<0.001),and it increased in the lateral femoris,semitendinosus and biceps femoris(|Z|>4.808,P<0.001).The scores of WOMAC,VAS,Tinetti Balance and Gait Score,and distances of 6-MWT improved in both groups after treat-ment(|t|>3.987,P<0.001),and improved more in the experimental group than in the control group,except the VAS score(|t|>2.213,P<0.05). Conclusion Manual therapy focusing on activation of rectus femoris,medial femoris and medial head of gastrocnemius,inhibition of the lateral femoris,semitendinosus and biceps femoris,and releasing the tension of the medial and lateral collateral ligaments,according to the results of surface electromyography,can alleviate the pain of the KOA in the older people and improve the mobility of the knee.
