Effect of pelvic floor muscles exercises by extracorporeal magnetic innervations on the bladder neck and urinary symptoms.

Background: This 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.

Methods: Twenty 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.

Results: The 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).

Conclusion: The ExMI is effective for SUI by strengthening the pelvic floor muscle without significantly decreasing BN mobility.
