Brief Summary:
This pilot clinical study, which focuses on feasibility and proof-of-principle, will be conducted in 11 female subjects (55-100 years old) with UI. Subjects will use the device three times a week for 8 weeks and complete 3-day "voiding diaries" to record instances of UI episodes and OAB quality of life.

Arm Intervention/treatment
Experimental: TENS Treatment Arm
This study is an early feasibility study which will be treating all patients at least 3 times per week, for 8 weeks, using the device.
Device: TENS
Transcutaneous electrical nerve stimulation

Primary Outcome Measures :
  1. Change in Urge Incontinence Episodes [ Time Frame: Baseline and 8 weeks ]

Secondary Outcome Measures :
  1. Change in Micturitions Per Day [ Time Frame: Baseline and 8 weeks ]
    Mean number of urinary voids per day (taken over a 3-day period)

  2. Change in Health-related Quality of Life (HRQL) [ Time Frame: Baseline and 8 weeks ]
    Change in incontinence health-related quality of life (HRQL) scores compared to pre-treatment. The survey consists of 13 questions that can be scored from 1 to 6. Lower scores correspond with better quality of life. The lowest score possible is 13 and the highest is 78.
