Urinary incontinence is a syndrome characterized by involuntary loss of urine.Overactive bladder (OAB) is a syndrome characterized by urgency and frequency, with or without urge incontinence. Extracorporeal electromagnetic stimulation (EMS) has been successfully applied for the treatment of stress urinary incontinence. We report our experience of using extracorporeal electromagnetic stimulation for patients with concurrent OAB and urinary incontinence, and investigate predictors for successful treatment.


Between 2009 and 2017, 162 patients (88 women and 74 men), who presented withOAB symptoms and urinary incontinence treated with EMS treatment, were enrolled in this study. The NeoControl chair (NeoTonus, Marietta, GA, USA) was then used in combination with oral medication, and treatment consisted of 2 sessions per week for 9 weeks. Treatment results were assessed by global response assessment. The overactive bladder symptom score (OAB-SS) questionnaire was recorded before and after treatment.


The mean age of the enrolled patients was 66.9 ± 13.8 years. All patients tolerated the treatment without any adverse event. Total 103 patients (63.6%) reported improved outcomes (GRA ≧ 1). The mean total OABSS score decreased significantly after treatment (10.4 ± 3.1 versus 6.1 ± 3.5, p < 0.01). Pure stress urinary incontinence patients showed less improvement when compared to patients with mixed urinary incontinence or pure urgency urinary incontinence.


Treatment course involving EMS of the pelvic floor can improve the symptoms of most OAB patients with synchronous incontinence symptoms. EMS could therefore be considered as an alternative treatment for patients with OAB and urinary incontinence.
