Clinical Study Of Muscle Strength Training In The Treatment Of Knee Osteoarthritis

Background:Knee osteoarthritis is a chronic degenerative disease,which is more common in middle-aged and elderly people.It is commonly associated with knee pain,decreased muscle strength in the lower extremities,and progressive knee dysfunction.According to research,exercise therapy can effectively reduce pain and improve dysfunction.Sling exercise therapy,as a new exercise therapy in recent years,is mainly used to improve the function of musculoskeletal.The use of advanced training methods can improve muscle strength,muscle endurance,joint mobility,flexibility,balance and so on.Objective:To observe the clinical effect of sling exercise therapy on knee osteoarthritis.Methods:40 patients with knee osteoarthritis were randomly divided into an experimental group and a control group,with 20 cases in each group.Thecontrol group used two physical therapies,ultrashort wave and wax therapy.The experimental group added sling exercise therapy on the basis of the control group,mainly training the strength of the quadriceps and hamstring muscles.Both groups were treated once a day,10 times as a course of treatment,rested for 3 days between treatment sessions,2 courses were limited to statistical effect.Rehabilitation assessment tests and comparisons were performed before treatment and after 2 courses of treatment.The rehabilitation assessment was performed by manual muscle test(MMT),Japanese orthopaedic association(JOA)score on ADL of the knee joint,AROM of the knee joint,and visual analogue scale(VAS)of pain.Results:After treatment,the muscle strength,ADL,AROM and VAS of the two groups of patients were improved compared with before treatment,and the difference was statistically significant(P <0.05);compared between the groups,the muscles around the knee joint The scores of force,ADL,AROM and VAS were better than those of the control group,the difference was statistically significant(P <0.05).Conclusion:Sling exercise therapy can effectively improve the clinical symptoms and functions of patients with knee osteoarthritis.Traditional physical therapy combined with active muscle training can achieve better results.
