Clinical Study Of Electromyographic Biofeedback Therapy Combined With Trunk Control Training On Shoulder Subluxation In Stroke Patients

Objective: This study was conducted to observe the therapeutic effects of electromyographic biofeedback combined with trunk control training on shoulder subluxation in stroke patients by measuring the distance between shoulder peak and humeral head,scapular position and upper limb motor function score,and to explore its mechanism of action to provide theoretical basis for clinical treatment.Methods:Thirty stroke patients with shoulder subluxation were chosen as test subjects and,using the random number table method,were split into 15 cases each for the experimental group and the control group.The experimental group got trunk control training based on myoelectric biofeedback five times per week for the course of the intervention,whereas the control group received standard rehabilitation therapy.In order to compare the affected upper limb muscle strength,pain visual analog score,affected Fugl-Meyer(FMA)upper limb function score,and modified Barthel index score between the two groups,X-rays,assessment scales,and soft ruler measurements were used before and after treatment.SPSS 25.0 statistical software was used to analyze the data.P 0.05 was considered statistically significant when the data were examined using the statistical program SPSS 25.0.Results:1.There was no significant difference in general information such as age,course of disease,gender,and stroke type between the two groups of patients through statistical analysis,and there was also no significant difference in evaluation indicators such as AHI and FMA before intervention(P>0.05).2.The AHI values of the patients in both groups,control group(20.9±2.1)mm and test group(18.9±2.6)mm,were decreased after the intervention of 4weeks.The test group significantly underperformed the control group(P = 0.027 < 0.05),and the difference was statistically significant(P < 0.05).3.The test group significantly outperformed the control group(P=0.017<0.05)after the intervention lasted for 4 weeks,with the vertex distance of the subscapularis angle measuring(16.1±2.0)cm in the control group and(18.3±2.4)cm in the test group with statistically significant differences(P<0.05).4.Following the intervention,the injured upper limb’s muscle strength was improved in both groups(P<0.05),with the test group outperforming the control group(P=0.01<0.05).5.Following the intervention,the visual analogue pain score was considerably reduced in both groups(P < 0.05),with the test group having a lower score than the control group(P < 0.05).6.After 4 weeks of intervention,the FMA score increased to(20.7±3.82)in the control group and(26.9±3.16)in the test group,and the FMA score was statistically significant in both groups(P<0.05),and the test group was more significant than the control group(P=0.000<0.05).7.After 4 weeks of intervention,the MBI score results were(28.33±6.7)in the control group and(38.33±6.5)in the test group,and both groups showed a significant increase(P<0.05),and the test group was higher than the control group(P=0.000<0.05).)score in the control group and(38.33±6.5)score in the test group,both groups showed a significant increase(P<0.05),and the test group was higher than the control group(P=0.000<0.05).Conclusion:It is worthy of therapeutic promotion that electromyographic biofeedback and trunk control training can effectively enhance the rehabilitation of shoulder subluxation.
