About this study

Official title: Percutaneous Tibial Nerve Stimulation (PTNS) Therapy for Female Patients Suffering From Multiple Sclerosis

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PTNS TreatmentDevice

    Also called Urgent PC Neuromodulation System

    Patients will be placed in a comfortable position, sitting or supine. The treatment leg will be propped up comfortably on a footrest but draped and out of view from the patient. A 34-gauge needle electrode will be inserted at a 60-degree angle 5 cm cephalad to the medial malleolus and slightly posterior to the tibia. A PTNS surface electrode will be placed on the ipsilateral calcaneus as well as 2 inactive sham surface electrodes, 1 under the little toe and 1 on the top of the foot. When the PTNS lead set is connected to the Urgent PC stimulator, a current level of 0.5 to 9 mA at 20 Hz is selected based on each patient's foot and plantar motor and sensory responses. Treatment lasts 30 minutes and given once weekly for 12 consecutive weeks.

  • Sham PTNS TreatmentDevice

    Also called Biostim Transcutaneous electrical nerve stimulation (TENS) Unit

    Patients will be positioned similarly as PTNS patients. A Streitberger needle will be used at the tibial nerve insertion site as described above to simulate needle placement. Three electrodes will be placed on the patient's foot, two active TENS electrodes and one inactive TENS electrode. The TENS "grounding pad" will be a gel electrode pad from a TENS unit device that is placed on the bottom of the foot just below the smallest toe. Another gel electrode will be placed on the top of the foot just above the small toe for conduction. These two electrodes will be connected to the TENS unit lead wires for sham stimulation. A third, inactive, gel electrode, will be placed near the medial aspect of the calcaneus to mimic the PTNS treatment. The TENS electrode will be connected by lead wires to the TENS unit set at 20 HZ. The TENS unit will be turned on and stimulation slowly increased to the patient's first sensory level and then turned off.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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

    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.

    Measured: One week after completing all 12 treatments

Secondary outcomes (4)
  1. Change in Urinary Voids in Response to the Treatment Using a 3-day Voiding Diary

    Study participants will complete a 3-day voiding diary to record number of voids. Investigators will analyze the change in urinary voids from before to after treatment. A positive number indicates more voids, and a negative number indicates fewer voids.

    Measured: At baseline and one week after completing all 12 treatments, Visit 13

  2. Change in Urinary Incontinence Episodes in Response to the Treatment Using a 3-day Voiding Diary

    Study participants will complete a 3-day voiding diary to record number of urinary incontinence episodes over a 3-day period. Investigators will analyze the change in urinary incontinence episodes from before to after treatment. A positive number indicates more episodes, and a negative number indicates fewer episodes.

    Measured: At baseline and one week after completing all 12 treatments, Visit 13

  3. Change in Urinary Urgency Episodes in Response to the Treatment Using a 3-day Voiding Diary

    Study participants will complete a 3-day voiding diary to record the number of urgency episodes over a 3-day period. Investigators will analyze the change in urinary urgency episodes from before to after treatment. A positive number indicates more episodes, and a negative number indicates fewer episodes.

    Measured: At baseline and one week after completing all 12 treatments, Visit 13

  4. Change in Overactive Bladder Symptoms in Response to the Treatment Using the Overactive Bladder Quality of Life Short Form Questionnaire.

    The Overactive Bladder quality of life questionnaire measures the impact of PTNS treatment on patient quality of life. Patients score symptom severity and impact on quality of life on a scale 1-6, with 1=not at all, 2=a little bit, 3=somewhat, 4=quite a bit, 5=a great deal, and 6=a very great deal. Symptom severity raw score is calculated from questions 1-6; the lowest possible raw score is 6, the highest score is 36. The health-related quality of life (HRQL) raw score is calculated similarly from questions 1-13; the lowest possible score is 13 and highest score is 78. The formula (actual raw score - lowest possible raw score)/highest possible raw score times 100 is applied to each raw score, which are added to give a final score in the range 0 to 166.6, with low scores indicating fewer symptoms and impact, and high scores indicating more symptoms and impact. Change from baseline is reported, with a positive number indicating worsening and a negative number indicating improvement.

    Measured: At baseline and one week after completing all 12 treatments, Visit 13

What does the primary outcome measure?

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). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
