Clinical Efficacy Of Electroacupuncture Combined With Constant Velocity Myocardial Training In The Treatment Of Knee Osteoarthritis

Objective and purpose:This study is a randomized controlled clinical study,using electro acupuncture,isokinetic training and electro acupuncture combined with isokinetic training to observe the clinical effect of these three different methods of treatment in Knee Osteoarthritis(KOA),in order to explore the best treatment method of this disease and to find the possible mechanism to provide clinical guidance for the treatment of KOA.Method:90 patients where selected from the department of Rehabilitation in Beijing University of Chinese Medicine Third Affiliated Hospital since January 2016 to February 2017.They are divided in three groups of 30 patients:A(Electro Acupuncture),B(Isokinetic Training)and C(Electro Acupuncture combined with Isokinetic Training).The diagnostic criteria is based on the KOA criteria of American College of Rheumatology in 1986 by Kellgren Lawranee(K-L)grading scale Xray rating to classified KOA’s patients.The treatment is 3 times per week,and 4 weeks per session,and verified the treatment effect after each session.And the specific pattern to observe in this project including:Visual Analogue Scale(VAS),the Peak Torque(PT),the Total Work(TW),the Average Power(AP),and the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC).Result:Before the treatment all groups submit in a statistical analyze in gender,age,duration of the disease,body weight,height,K-L Xray classification,VAS score,Isokinetic test with flexion and extension muscles groups(PT,TW and AP value),knee osteoarthritis score by WOMAC After analyzing there were no significant statistical difference between these three groups(p<0.05)which means the baseline data of these three groups were comparable.1)VAS comparison:the tree treatment methods can reduce the VAS score(p<0.05).The group A and C have a better VAS improvement than group B with statistical significance(p=0.000<0.05);there are no significant difference between group A and C(p=0.074>0.05),means the Electro Acupuncture may have better clinical effect in pain relieve than Isokinetic Training.2)WOMAC score comparison:after treatment the WOMAC scores(including Pain,Stiffness,Joint Function)in these 3 groups decreased significantly(p<0.05).And comparing between them,group C has the advantage,and group A and B had no difference(p=0.326).The Pain score had significant difference between the tree groups before and after treatment(p<0.05),which the decreased level were more visible in the group C,otherwise the group A and B had no difference(p=0.215>0.05);the Stiffness score in comparing with overall difference(p=0.041)after treatment,but there is a dispute in the statistical method,it’s not showing the comparison between groups;and the Joint Function score were significant difference(p<0.05)specifically in the group C;and group A and B were no difference(p=0.052>0.05).3)Comparison of the three group in PT,TW and AP value after treatment:these three method of treatment can improved the PT,TW and AP value in the flexor and extensor muscle group,there are also have statistical significance(p<0.05).The knee extension and flexion muscle in PT value has better improvement,the group C is the best,then group B,and the group A is the worst;TW value in flexor muscle comparing group A with B p=0.031<0.05,group A with C p=0.026<0.05 and group B with C p=0.048<0.05.The order of the knee flexion muscles with TW value improvement from high to low is:group C,B and A at the end.The knee extensor muscles with TW value comparison with three groups were found with more significant difference,the group C is better than group A and B,and the group B than the group A.For the flexor and extensor muscle group the AP value improvement were also statistically significant(p<0.05),the group C was better than group A and B,the group B was better than group A.Conclusion:Based on the results,all these three methods of treatment had significant effects on KOA patients,they can improve the patient’s VAS score,WOMAC score,also the PT,TW and AP value in the Isokinetic test.The Electro Acupuncture combined with Isokinetic Training group(group C)was shown a better effect value in above results than Electro Acupuncture group and Isokinetic Training group;but the Electro Acupuncture is better in the relief of pain than Isokinetic Training;the Isokinetic Training can increase patient’s PT,TW and AP value;and there are no difference in the improvement of WOMAC score between the Electro Acupuncture and Isokinetic Training.
