The Effect Of Baduanjin Exercise On Work-related Musculoskeletal Disorders Of The Neck And Shoulder Among Rehabilitation Therapists

Objective:Use electromyography for measuring the neck and shoulder muscles(anterior deltoid,middle deltoid,posterior deltoid,upper trapezius,middle trapezius,infraspinatus,pectoralis major and serratus anterior)surface electromyography before and after baduanjin exercise,quantitatively analyzing the sEMG characteristic of baduanjin exercise on neck and shoulder muscles,and use VAS and SAS to evaluate the fitness effects of baduanjin exercise for preventing work-related musculoskeletal disorders of the neck and shoulder among rehabilitation therapists,which provided theoretical basis for the promotion and application of baduanjin in the future and the relevant research on neck and shoulder diseases.Methods:32 rehabilitation therapists who had work-related musculoskeletal disorders of the neck of shoulder were selected and randomly divided into control group and baduanjin group,with 16 in each group.patients in baduanjin group received the baduanjin exercise for 12 weeks,and those in control group maintained their original activity habit.The main measurement index was electromyography,the secondary index were VAS and SAS.Select anterior deltoid,middle deltoid,posterior deltoid,upper trapezius,middle trapezius,infraspinatus,pectoralis major and serratus anterior of the dominant side,and record their average EMG amplitude(AEMG)during the first movement to the last movement of baduanjin;respectively record the muscles's MVCAEMG,MVCMPF,MVCMF,VAS and SAS of the two groups before experiment and after experiment.Results:There was no significant difference in the general characteristics between the two groups,such as sex ratio,average age,height,weight,disease course and basic exercise time(P>0.05).The AEMG of the upper trapezius was the highest in the first,second,fifth and sixth movements of baduanjin,the AEMG of the anterior deltoid was the largest in the third and seventh movements,the AEMG of the middle trapezius was the largest in the fourth movement,and the AEMG of the pectoralis major from the first movement to the seventh movement was minimum.After experiment,the MVCAEMG,MVCMPF and MVCMF of the muscles in baduanjin group showed no statistical significance(P>0.05)compared with that before experiment,but in the control group,MVCAEMG,MVCMPF and MVCMf of the anterior deltoid,posterior deltoid,upper trapezius and infraspinatus showed significant decrease compared with that before experiment(P<0.05);after experiment,the MVCAEMG,MVCMPF and MVCMF of the anterior deltoid,upper trapezius and middle trapezius in control group were all lower than those in baduanjin group(P<0.05);after experiment,VAS of baduanjin group was significantly improved compared with that of control group,and the difference was statistically significant(P<0.05),the VAS of the control group was significantly increased after experiment compared with that before experiment,and the difference was statistically significant(P<0.05);after experiment,SAS of baduanjin group was significantly improved compared with that of control group,and the difference was statistically significant(P<0.05),the SAS of control group was significantly increased after experiment compared with that before the experiment,and the difference was statistically significant(P<0.05).Conclusion:Regular baduanjin exercise has a good effect for relieving the neck and shoulder muscle fatigue,pain and anxiety of rehabilitation therapists.Baduanjin is a safe,effective,and beneficial daily physical exercise,which is worthy of promotion and application in the occupational population of rehabilitation therapists.
