Posterior Tibial Nerve Stimulation's Effectiveness in UI Frequency in Overactive Patients in Home

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.

Inclusion Criteria:

1. Females
2. 55-100 years old
3. Have an average urinary frequency of ≥ 8 voids per 24 hours (based on a pre-treatment 3-day voiding "training" diary)
4. Have self-reported bladder symptoms of more than 3 months
5. Are ambulatory and able to use the toilet independently
6. Have been off antimuscarinics, anticholinergics or beta-3 agonists for at least 2 weeks prior to enrollment OR on a stable dose for the prior 3 months
7. Patient has urinary urge incontinence of ≥ 8 episodes from a 3-day diary (with incontinence associated at urge level moderate or severe)
8. Able to provide informed consent
9. Capable and willing to follow all study-related procedures

Exclusion Criteria:

1. Have primary complaint of stress urinary incontinence
2. Have a pacemaker or implantable defibrillator
3. Had botox injections in the bladder or pelvic floor muscles in the past 12 months
4. Have a current urinary tract or vaginal infection
5. Have an active implantable SNS device (InterStim & Bion)
6. Have been diagnosed with peripheral neuropathy or nerve damage
7. Currently pregnant
8. Deemed unsuitable for enrollment in study by the investigator based on subjects' history or physical examination
