Study On The Correlation Between Acupuncture Efficacy Of Knee Osteoarthritis Of Cold Dampness Bi Obstruction Type And Expectation

Objective:Acupuncture expectation value refers to the degree of hope that patients have for their condition improvement and acupuncture treatment,which is one of the important components of the non-specific effect of acupuncture.In this study,patients with knee osteoarthritis were taken as the research objects to observe whether acupuncture expectation value had an impact on the therapeutic effect of acupuncture on this disease.Methods:This study will subject "acupuncture auxiliary breast pain spread transdermal therapy treatment of cold dampness Bi obstruction knee osteoarthritis clinical randomized controlled studies" in the control group of patients included in the study,a total of 73 cases,fall off 6 cases,to patients with acupuncture and moxibustion expectations of high and low,is divided into high expectation and low expectation group,two groups of both the conventional acupuncture,retaining needle 30 min every time.A total of 10 times of treatment,5 times a week,2 weeks of continuous treatment,and 10 days after the end of treatment follow-up.The main evaluation index was WOMAC osteoarthritis Scale,and the secondary evaluation index was Visual Analogus Scale(VAS),anxiety self-rating Scale and depression self-rating Scale.The patients were evaluated before treatment,after treatment and during follow-up to observe the effect of acupuncture expectation on acupuncture efficacy.Results:(1)comparison at baseline:comparison of general conditions of subjects in the two groups:age,gender,X-ray grade,and disease course were all p>0.05,and there was no significant difference between the two groups,which was comparable.There was a significant difference in the optimism score between the two groups.Baseline comparison of pain,stiffness and dysfunction in the WOMAC osteoarthritis scale:p>0.05.There was no significant difference in WOMAC scores between the two groups,suggesting comparability.Secondary evaluation index:baseline comparison of visual analogue scale(VAS)of pain,p>0.05,showed no significant difference in VAS scores between the two groups and was comparable.Baseline comparison of anxiety self-rating scale(SAS)and depression self-rating scale(SDS):p<0.05,the level of patients'expectation was negatively correlated with SAS score and SDS score at baseline.Through the regression analysis,it was found that the factors affecting the level of expectation were baseline optimistic score,SAS score and SDS score,and there was no collinearity among them.(2)comparison in the treatment group:main evaluation indexes:the scores of pain,stiffness and dysfunction in WOMAC osteoarthritis scale before and after treatment,before and after treatment,and after treatment and during follow-up:p<0.05,the difference was statistically significant.VAS scores were compared before and after treatment,before and after treatment,and after treatment and during follow-up:p<0.05,showing statistically significant differences.Comparison of SAS and SDS before and after treatment,before and follow-up,and after treatment and follow-up:p<0.05,the difference was statistically significant.(3)comparison between groups after treatment:the main evaluation index was WOMAC osteoarthritis Scale.After treatment,the scores of pain,stiffness and dysfunction of the two groups were compared:0.01<P<0.05,and the difference was statistically significant.During the follow-up,scores in three aspects were compared:0.01<P<0.05,and the difference was statistically significant.Comparison of efficacy between the two groups after treatment:P<0.05,the difference was statistically significant.Secondary evaluation index:VAS score:Comparison of VAS scores between the two groups after treatment and during follow-up,both 0.01<P<0.05,and the difference was statistically significant.Self-rating Anxiety scale(SAS)and self-rating depression Scale(SDS):Compared with follow-up visits after treatment,P<0.05 was found to be statistically significant.However,there were differences in the condition improvement of the two groups,which could not indicate that the improvement of SAS and SDS after treatment was due to the expected effect of acupuncture.Conclusion:(1)There was a difference in efficacy between the high expectation group and the low expectation group.High expectation may mediate better acupuncture efficacy.(2)The degree of optimism and psychological state of the subjects may influence the level of acupuncture expectations of the subjects.(3)Acupuncture and moxibustion is safe and effective in treating knee osteoarthritis of cold,dampness and stuffiness,and can improve the pain,stiffness and dysfunction of knee osteoarthritis.(4)The psychological state of the subjects improved after treatment,but it could not be determined whether it was due to the expected effect of acupuncture.
