The purpose of this study is to understand how the frequency of PTNS sessions impacts their efficacy in the treatment of over active bladder syndrome.

This study aims to evaluate the impact of the periodicity of the PTNS treatments on the efficacy of treating patients with OAB. We will compare the efficacy of a condensed (twice weekly) protocol to the standard (once per week) protocol of PTNS therapy.

Objective #1 (6-wk CP vs. 12-wk SP) is to show that 6 weeks of the condensed protocol (CP) will yield a higher efficacy compared to the standard 12-week protocol (SP). If this 6-week CP is proven effective, candidates for PTNS treatment could potentially experience symptom relief in half the time as the current standard of care, improving their quality of life quicker. Objective #2 (12-wk CP vs. 12-wk SP) is to show that 12 weeks of the CP will have a higher efficacy compared to the 12-week SP. If the superiority of this 12-week CP is proven, it could be beneficial in treating patients with refractory OAB.

Inclusion Criteria:

• Women and men (18 years of age and older) with overactive bladder syndrome, who are interested in receiving PTNS treatment.

Exclusion Criteria:

• Patients with anatomical limitations preventing successful placement of the electrode, medical disorders precluding stimulation (bleeding disorders, cardiac pacemakers, peripheral vascular disease or ulcers, or lower leg cellulitis).
• Pregnant women or women who are planning to become pregnant during the course of the study.

Patients in both CP and SP groups will come to the clinic twice per week, and will not know their group assignment until the end of the study.

All the interventions will be performed by the sub-investigator. The care providing physician will not know the group assignment of the patients.
