| Objective:To observe the rehabilitation effect of pelvic floor magnetic stimulation combined with biofeedback electrical stimulation on pelvic floor dysfunction in parturient women with spontaneous delivery,so as to provide a basis for combined magnetic and electrical intervention in the rehabilitation of postpartum pelvic floor dysfunction,and to provide a new scheme for postpartum pelvic floor rehabilitation.Methods:A total of 142 parturients who met the inclusion and exclusion criteria in the pelvic floor muscle clinic of a Grade 3A Hospital in Changchun City,Jilin Province from October 2019 to July 2020 were randomly divided into combined intervention group(n=71)and control group(n=71).Subjects in the combined intervention group received magnetic stimulation and biofeedback electrical stimulation on the basis of standard nursing intervention,while subjects in the control group received only biofeedback electrical stimulation on the basis of standard nursing intervention.Before intervention,the muscle strength of the pelvic floor was measured by hand,the prolapse of pelvic organs was observed,the grade of urinary incontinence was confirmed by urinary incontinence questionnaire,and the value of pelvic floor EMG was detected by surface EMG of pelvic floor muscle.All data analysis was performed using SPSS 24.0 statistical software.The data conforming to the normal distribution adopts the paired sample T test,and the data of non-normal distribution adopts the Wilcoxon paired rank test.and P<0.05 was taken as the difference with statistical significance.The pelvic floor muscle strength,pelvic organ prolapse,urinary incontinence and surface electromyography were compared before and after treatment.Results:1.Effect of combined magnetic and electrical intervention on pelvic floor muscle strength:before intervention,the pelvic floor muscle strength of the combined intervention group and the control group were 1.00(1.00,1.75)and 1.00(1.00,2.00)respectively,and there was no significant difference between the two groups(P>0.05).After intervention,the pelvic floor muscle strength of the combined intervention group and the control group were 3.00(2.00,3.00)and 2.00(2.00,3.00)respectively.Compared with before intervention,the muscle strength of pelvic floor muscle in both groups was significantly improved,and the difference was statistically significant(P<0.05).After intervention,the pelvic floor muscle strength of the combined intervention group was significantly higher than that of the control group(P<0.05).2.Effect of combined magnetic and electrical intervention on pelvic organ prolapse:before the intervention,the degree of pelvic organ prolapse in the combined intervention group were:28 cases of degree Ⅰ,33 cases of degree Ⅱ,and 3 cases of degree Ⅲ;the degree of pelvic organ prolapse in the control group were:29 cases of degree I,31 cases of degree Ⅱ,and 3 cases of degree Ⅲ.There was no significant difference between the two groups before the intervention(P>0.05).After intervention,the degree of pelvic organ prolapse in combined intervention group were:3 cases of 0 degree,50 cases of degree Ⅰ,and 11 cases of degree Ⅱ;the control group pelvic organ prolapse degree:35 cases of degree Ⅰ,27 cases of degree Ⅱ,and 1 case of degree Ⅲ.Compared with before intervention,the degree of pelvic organ prolapse of the two groups of subjects was significantly improved(P<0.05).After intervention,the prolapse of pelvic organs in the combined intervention group was significantly better than that in the control group,and the difference was statistically significant(P<0.05).3.The ICI-Q-SF score of the combined intervention group decreased from 4(0,5)points before treatment to 0(0,0)points(P<0.05).After biofeedback electrical stimulation,the ICI-Q-SF score of the control group decreased from 4(0,6)to 0(0,0)(P<0.05).Compared before treatment,the ICI-Q-SF were significantly reduced after treatment in the two groups(P<0.05),and the reduction in the intervention group was superior to that in the control group(P<0.05).4.The effect of the combined magnetic and electrical intervention on the average value of EMG in the pre-resting stage of pelvic floor muscle:before intervention,the average value of EMG in the combined intervention group and the control group was 2.09(1.42,3.22)μV and 1.77(1.40,2.20)μV,respectively,and there was no significant difference(P>0.05).After intervention,the average value of EMG before rest in the combined intervention group and the control group was 2.57(1.48,3.23)μV and 1.87(1.60,2.50)μV,respectively,which was significantly higher than that of the intervention(P<0.05),and there was significant difference between the two groups(P<0.05).5.The effect of the combined magnetic and electrical intervention on the maximum EMG of pelvic floor muscle during rapid contraction:before intervention,the maximum EMG of the combined intervention group and the control group during rapid contraction were(20.51±8.49)μV and(22.20±4.99)μV,respectively,and there was no significant difference between the two groups(P>0.05).After intervention,the maximum value of EMG in the rapid contraction phase of the combined intervention group and the control group was(36.42±7.68)μV and(31.66±4.27)μV,respectively,which was significantly higher than that of the intervention(P<0.05),and there was significant difference between the two groups(P<0.05).6.The effect of the combined magnetic and electrical intervention on the average EMG of the pelvic floor muscle during tension and contraction:before intervention,the average EMG of the combined intervention group and the control group were 13.14(8.11,18.80)μV and 16.00(11.50,19.00)μV,respectively,and there was no significant difference between the two groups(P>0.05).After intervention,the average value of EMG in the combined intervention group and the control group were 22.90(19.72,29.02)μV and 22.00(16.80,23.60)μV,respectively,which was significantly higher than that before intervention(P<0.05).The average value of EMG in the combined intervention group was significantly higher than that in the control group(P<0.05).7.The effect of the combined magnetic and electrical intervention on the average EMG of pelvic floor muscle during endurance contraction:before intervention,the average EMG of the combined intervention group and the control group were 11.08(8.27,17.04)μV and 14.50(11.00,17.00)μV,respectively,and there was no significant difference between the two groups(P>0.05).After intervention,the average values of EMG in the endurance contraction phase of the combined intervention group and the control group were 22.46(17.17,26.84)μV and 19.30(16.54,22.40)μV,respectively,which was significantly higher than those before intervention(P<0.05).There was a significant difference in the average value of EMG during endurance contraction between the two groups after intervention(P<0.05).8.The effect of the combined magnetic and electrical intervention on the average value of EMG in the post-resting stage of pelvic floor muscle:before intervention,the average value of EMG in the combined intervention group and the control group were 2.00(1.64,3.20)μV and 2.00(1.68,2.31)μV,respectively,and there was no significant difference between the two groups(P>0.05).After intervention,the average value of EMG in the combined intervention group and the control group was 2.82(1.52,3.28)μV and 2.40(2.00,3.20)μV,respectively,which was significantly higher than that of the intervention(P<0.05),and there was significant difference between the two groups(P<0.05).Conclusion:1.Biofeedback electrical stimulation can promote the recovery of the pelvic floor muscle function of parturient women.2.Compared with single biofeedback electrical stimulation,the combined application of magnetic stimulation and biofeedback electrical stimulation enhances the recovery of the pelvic floor muscle function of parturient women. |
