Efficacy of Transcutaneous Functional Electrical Stimulation on Urinary Incontinence in Myelomeningocele: Results of a Pilot Study

Purpose To investigate the efficacy of transcutaneous functional electrical stimulation (FES) on voiding symptoms in children with myelomeningocele (MMC) suffering from neuropathic urinary incontinence Materials and Methods Six girls and 6 boys with moderate to severe urinary incontinence secondary to MMC were included Median age of children was 5 04 (range 3-11) years They underwent a urodynamic study (UDS) before and 3 months after FES with special attention to detrusor leak point pressure (DLPP) and maximal bladder capacity (MBC) Daily incontinence score, frequency of pad changing, and enuresis were also assessed before and three months after treatment Fifteen courses of FES for 15 minutes 3 times per week were performed with low frequency (40 Hz) electrical current, duration of 250 mu s, with hold and rest time of 2 seconds Results Nine children had improvement on urinary incontinence score, while three children had no improvement Median DLPP was significantly increased from 38 5 (range 12-50) cm H2O to 59 5 (range 18-83) cm H2O (P = 0 003) MBC was significantly increased from median value of 155 (range 60-250) mL to 200 (range 110-300) mL (P = 0 007) Conclusions This is a pilot study showing that FES therapy might have positive effects on improvement of voiding symptoms of MMC children with neurogenic urinary incontinence in terms of daily incontinence score and UDS parameters
