Purpose: To assess the efficacy of combined transcutaneous interferential (IF) electrical stimulation and pelvic floor muscle training through biofeedback on non-neuropathic urinary incontinence in children.
Methods: This prospective study comprised of 46 anatomically and neurologically normal children (9 boys, 37 girls; mean age of 8.4 ± 2.2 years old) with non-neuropathic urinary incontinence. All children were evaluated by kidney and bladder ultrasounds, uroflowmetry with electromyography (EMG), a complete voiding diary and a dysfunctional voiding scoring questionnaire at the baseline. Children were randomly allocated into two treatment groups including group A (n = 23) who underwent biofeedback therapy in addition to IF electrical stimulation and group B (n = 23) who received only biofeedback therapy. Re-evaluation was performed 6 months and one year after completion of the treatment sessions.
Results: Improvement of non-neuropathic urinary incontinence was significantly higher in group A in comparison to group B at two follow ups (P < 0.05). Daytime incontinence was improved in 19/23(82%) and 13/23(56.5%) of children in groups A and B respectively after the treatment (P < 0.01). There was no significant difference in uroflowmetry measures between two groups after the treatment.
Conclusions: Combination of biofeedback therapy and transcutaneous IF electrical stimulation is a potential effective modality in treating non-neuropathic urinary incontinence in children.
Level of evidence: Type of study: Treatment study. Level I: Randomized controlled trials with adequate statistical power to detect differences (narrow confidence intervals) and follow up >80%.
