| Objective:To observe the effects of electroacupuncture at the abdominal acupoints of the Spleen Meridian on the balance function of patients with stroke,and to analyze the changes of core muscle groups before and after treatment with surface electromyography.Methods:According to the principle of random grouping,68 patients with stroke and hemiplegia were randomly divided into electroacupuncture group and control group,with 34 cases in each group,and 64 cases were completed,32 in each group.Control group:basic medical disease treatment combined with conventional acupuncture and conventional rehabilitation training;electro-acupuncture group:electro-acupuncture at SP13,SP14,SP15,SP16(both sides)based on the control group.The above two groups were treated for 4 weeks.The two groups were evaluated by the Berg Balance Scale(BBS),the Tinetti Performance Oriented Mobility Assessment(Tinetti POMA),and the Modified Barthel Index(MBI)before treatment,after 2weeks,and after 4 weeks.Surface electromyography was performed before and 4 weeks after treatment.Results:(1)The results of the Berg Balance Scale(BBS)scoring study:Compared with before treatment,the scores of the two groups of patients increased after 4 weeks of treatment(P<0.01);there was no statistical difference between the two groups before treatment and after2 weeks of treatment(P>0.05);after 4 weeks of treatment,the electroacupuncture group score was higher than the control group(P<0.01).(2)The results of the Tinetti Performance Oriented Mobility Assessment(Tinetti POMA)scoring study:Compared with before treatment,the scores of the two groups of patients increased after 4 weeks of treatment(P<0.01);there was no statistical difference between the two groups before treatment and after 2 weeks of treatment(P>0.05);after 4 weeks of treatment,the electroacupuncture group score was higher than the control group(P<0.01).(3)The results of the Modified Barthel Index(MBI)scoring study:Compared with before treatment,the scores of the two groups of patients increased after 4 weeks of treatment(P<0.01);there was no statistical difference between the two groups before treatment and after2 weeks of treatment(P>0.05);after 4 weeks of treatment,the electroacupuncture group score was higher than the control group(P<0.01).(4)Electromyographic findings from sitting to standing surface:Compared within the group,the RMS of transverse abdominal muscles muscle and multifidus muscles in both groups were higher than before treatment(P<0.01 in the electroacupuncture group and P<0.05 in the control group);The RMS of both external abdominal oblique muscles in the electroacupuncture group were higher than before treatment(P<0.01 on the hemiplegic side,P<0.05 on the non-hemiparalytic side),and the RMS on both external abdominal oblique muscles in the control group was also higher than before treatment(P<0.05);The RMS of the erector spinae muscles in the non-hemiplegic side of both groups was higher than before treatment(P<0.05),and the electro-acupuncture group had lower RMS of hemiplegic erector spinae compared with before treatment(P<0.05);the RMS of the erector spinae muscle in thehemiplegic side of the control group was lower than before treatment,but the difference was not statistically significant(P>0.05).Compared between groups,the RMS of both abdominal transverse muscle and multifidus muscles in the electroacupuncture group were higher than those in the control group(P<0.01 on the hemiplegic side,P<0.05 on the non-hemiplegic side);the RMS of hemiplegic external oblique muscles after treatment in electroacupuncture group was higher than control group(P<0.05);There was no statistically significant difference between the RMS of bilateral erector spinae and non-hemiplegic external oblique muscles after treatment with the control group(P>0.05).Compared with the non-hemiplegic side and the hemiplegic side,the RMS about non-hemiparalysis side of the transverse abdominal muscle,multifidus muscle,and external oblique muscles of the two groups was higher than the hemiplegic side before treatment(P<0.05,P<0.01),the RMS about hemiplegic side of the erector spinae was higher than the non-hemiplegic side before treatment(P<0.01);there was no statistically significant difference between the two sides in the RMS of abdominal transverse muscles and multifidus muscles after treatment in the electroacupuncture group(P>0.05),the RMS about non-hemiparalysis side of the transverse abdominis and multifidus muscles of the control group was higher than that of the hemiplegic side after treatment(P<0.05);The non-hemiplegic side of the two groups of external oblique muscles RMS after treatment was higher than that of the hemiplegic side(P<0.05 in the electroacupuncture group,P<0.01 in the control group);the hemiplegic side of the erector spinae RMS after treatment in both groups was higher than that in the non-hemiplegic side(P<0.05 in the electroacupuncture group and P<0.01 in the control group).(5)Study results of sEMG by turning back:Compared within the group,the RMS of bilateral abdominal transverse muscle and multifidus muscles in both groups were higher than before treatment(P<0.01 in the electroacupuncture group and P<0.05 in the control group);The RMS of bilateral erector spinae in both groups was lower than before treatment,but compared with before treatment,the difference was not statistically significant(P>0.05).Compared between groups,the RMS of bilateral abdominal transverse muscles and multifidus muscles in the electroacupuncture group were higher than those in the control group(P<0.01);the RMS of bilateral external oblique muscles of the electroacupuncture group was higher than that of the control group after treatment(P<0.05);there was no statistically significant difference between the RMS of bilateral erector spinae after treatment in the electroacupuncture group and the control group(P>0.05).Compared with the non-hemiplegic side and the hemiplegic side,there was no statistically significant difference between the two groups of patients before and after treatment in both sides of the external oblique RMS(P>0.05),the RMS turning side of the transverse abdominal muscles is higher than that of the non-turning side(P<0.05),the RMS turning side of the erector spinae is higher than the non-turning side(P<0.01),and the RMS non-turning side of the multifidus muscles is higher than the turning side(P<0.01).Turning to look behind the non-hemiplegic side,the RMS of both external abdominal oblique muscles in the electroacupuncture group were higher than before treatment(P<0.01 on the hemiplegic side,P<0.05 on the non-hemiplegic side),the RMS of the external oblique muscles of the hemiplegic side on the control group was also higher than before treatment(P<0.05),compared with before treatment,there was no statistically significant difference in the RMS of the external abdominal oblique muscle in the non-hemiplegic side of the control group(P>0.05);Turning to look behind the hemiplegic side,the RMS of bilateral external abdominal oblique muscles in the electroacupuncture group washigher than before treatment(P<0.01 on the non-hemiplegic side,P<0.05 on the hemiplegic side),and the RMS of the external abdominal oblique muscles on the non-hemiplegic side of the control group was also higher elevated before treatment(P<0.05),compared with the pre-treatment RMS of hemiplegic external abdominal oblique muscles in the control group,the difference was not statistically significant(P>0.05).Conclusions:Electroacupuncture of the Spleen Meridian through the abdominal acupoint can effectively improve the balance and gait function,as well as the ability of daily life of stroke patients,which can also effectively promote the recovery of core muscle functions. |
