| Objective and methods:Neurogenic bladder is one of the common complications after spinal cord injury.Functional magnetic stimulation has been shown to be effective in the treatment of patients with neurogenic bladder,but there is no standard treatment for this technique.This study on the sacral merger of neurogenic bladder after spinal cord injury patients as the main research object,on the basis of the conventional treatment methods,gives the different frequencies of functional magnetic stimulation treatment,observing the index,the assessment of functional magnetic stimulation in the intervention of patients with neurogenic bladder after spinal cord injury clinical curative effect,comparing the influence of different frequency magnetic stimulation of micturition function of patients with,To provide reference for the selection of clinical treatment parameters.Methods:A total of 85 patients with neurogenic bladder caused by supresacral spinal cord injury who were hospitalized in the Department of Rehabilitation Medicine of the First Affiliated Hospital of Guangxi Medical University from January 2019 to March 2021 and met the inclusion criteria were selected and randomly divided into the control group(n=22)and the observation group(n=63)(n=21 in the 15Hz group,21 in the 20Hz group,and 21 in the 25Hz group).On the basis of the same comprehensive treatment,observation group was treated with three different frequencies of functional magnetic stimulation of sacral 3 nerve roots.The treatment was observed for 2 weeks,and the efficacy was evaluated after treatment.Results:A total of 85 eligible subjects were included in this study,of which 5 cases were shed during the study,and 80 cases were finally completed(20 cases in the control group,19 cases in the 15Hz group,21 cases in the 20Hz group,and 20 cases in the 25Hz group).After treatment with different intervention regimens,there were significant differences in the indicators related to bladder function in each group before and after treatment,with statistical significance(P<0.05),suggesting that bladder function in all 4 groups was improved after treatment.The results of multiple comparisons between groups showed that there was a statistically significant difference in the maximum bladder volume between the control group and the 20Hz group(P<0.05),while there was no statistically significant difference in the pairwise comparison between the other groups(P>0.05).In terms of residual urine volume,the 20Hz group was lower than the other three groups,and the difference was statistically significant(P<0.05),while the pairwise comparison among the other groups showed no statistically significant difference(P>0.05).There were no significant differences in bladder filling pressure,24h frequency of urination and incidence of urinary tract infection among all groups(P>0.05).Neurogenic bladder symptom rating scale The total score of bladder symptom in the 4 groups was statistically significant(P<0.05),among which,there were statistically significant differences in scores between the control group and the 20Hz group,the control group and the 25Hz group,and the 15Hz group and the 25Hz group(P<0.05),and there was no statistical significance in the scores of other groups(P>0.05);In terms of quality of life score of neurogenic bladder symptom scale,the difference of quality of life score after different interventions was statistically significant(P<0.05),there was a statistically significant difference in the quality of life scores between the control group and the 20Hz group(P<0.05),while there was no statistically significant difference in the scores of patients in the other groups(P>0.05).Conclusion:Setting the frequency of functional magnetic stimulation to the sacral 3 nerve root at 20Hz can improve the urination function of patients with supracacral spinal cord injury complicated with neurogenic bladder and improve the quality of life of patients. |
