Overview
Brief Summary
This is a pilot, single blind, randomized, sham-controlled trial to assess the benefit of Percutaneous Tibial Nerve Stimulation (PTNS) in treating bladder overactivity (OAB) symptoms in multiple sclerosis (MS) patients. The data generated by this study would provide support for a future multi-institutional, randomized prospective trial.
Detailed Description
Multiple Sclerosis (MS) is a chronic, progressive inflammatory disorder of the central nervous system. It is caused by loss of myelin, the outer protective layer of the neuron, resulting in a disruption of the signal potentials that flow through the neurons. This can lead to a variety of sensory, visual, and motor disturbances. MS affects almost 1 million people in the United States with the prevalence being two to three times higher in women than in men. Over 80% of MS patients suffer from lower urinary tract symptoms, with OAB and urinary incontinence (UI) being the predominant bladder dysfunctions. OAB is characterized by sudden feeling of urgency, frequent urination, and urge incontinence. PTNS is an FDA approved treatment for OAB and is recommended as third line treatment for OAB by the American Urological Association (AUA) and Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction (SUFU). However, it is not approved for MS and as such these treatments are not covered by insurance. Here the investigators propose a pilot, double blind, randomized, sham-controlled trial to assess the benefit of PTNS in treating OAB symptoms in MS patients. The data generated by this study would provide support for a future multi-institutional, randomized prospective trial.

Outcomes
Primary Outcomes
The Overall Patient Reported Change of Bladder Overactivity (OAB) Symptoms in MS Patients as Reported on the Patient Global Impression of Improvement (PGI-I) Questionnaire
Time Frame: One week after completing all 12 treatments
The PGI-I is a self-reported measure of symptom change after treatment completion. This is a validated 1-question tool. Subjects score their urinary condition now compared to how it was before starting treatment. The score ranges from 1-7. 1= very much better, 2 = much better, 3 = a little better, 4=no change, 5= a little worse, 6= much worse, 7 = very much worse. A higher score indicates a worse outcome. Only one participant completed the primary outcome, thus that subject score will be reported.
Secondary Outcomes
- Change in Urinary Voids in Response to the Treatment Using a 3-day Voiding Diary(At baseline and one week after completing all 12 treatments, Visit 13)
- Change in Urinary Incontinence Episodes in Response to the Treatment Using a 3-day Voiding Diary(At baseline and one week after completing all 12 treatments, Visit 13)
- Change in Urinary Urgency Episodes in Response to the Treatment Using a 3-day Voiding Diary(At baseline and one week after completing all 12 treatments, Visit 13)
- Change in Overactive Bladder Symptoms in Response to the Treatment Using the Overactive Bladder Quality of Life Short Form Questionnaire.(At baseline and one week after completing all 12 treatments, Visit 13)
