BackgroundThis study aimed to investigate the changes in the bladder neck (BN) and urinary symptoms using extracorporeal magnetic innervation (ExMI) therapy before and after performing passive pelvic floor exercises.MethodsTwenty women with stress urinary incontinence (SUI) were assessed by transperineal ultrasound and questionnaires before and after the ExMI therapy from January 2011 to February 2021.ResultsThe incidence of urinary frequency and SUI were significantly decreased after the therapy (McNemar test, p < 0.01). The therapeutic efficacy of SUI was 75%. A significant decrease was noted in pad test results (paired t test, p < 0.05). At the same time, there was a considerable difference in Urinary Distress Inventory-6 scale measures (paired t test, p < 0.001). However, results for the Incontinence Impact Questionnaire-7 showed a marginally significant difference (paired t test, p = 0.066). Three domains of lubrication, orgasm, and satisfaction in the Female Sexual Function Index showed significant differences (paired t test, p < 0.05). Transperineal ultrasound found that BN mobility and Q-tip straining angle were not statistically significant (paired t test, p > 0.05).ConclusionThe ExMI is effective for SUI by strengthening the pelvic floor muscle without significantly decreasing BN mobility.Copyright © 2023, the Chinese Medical Association.
