A pilot study of the home application of transcutaneous neuromodulation in children with urgency or urge incontinence

Purpose: We evaluated the efficacy of transcutaneous neuromodulation to treat urinary urgency and urge incontinence in children with nonneurological bladder dysfunction. Materials and Methods: Surface neuromodulation was delivered via skin electrodes away from the genital region for a short duration daily on a home treatment basis. Clinical outcome was measured by 3 tools previously tested for reliability including the frequency volume chart, urgency visual analog scale and accident diary ("Dry Pie"). Results: After at least 1 month of application dryness had improved in 73.3% of children, mean urgency score had improved to equate action at urge as being 'easy to hold on' and there was a significant increase in mean voided volume. Conclusions: Initial evaluation of the home application of surface neuromodulation in children with urgency and/or urge incontinence revealed positive results and warrants a randomized controlled investigation. The finding that children were not completely dry with this treatment in isolation suggests that further study is needed to identify optimal treatment duration and stimulus intensity.
