Posterior Tibial Nerve Stimulation vs. Sham
A Phase 3 study testing Posterior Tibial Nerve Device in people with Overactive Bladder, run by Corewell Health East at 1 site in United States.
Trial summary
The overall goal of this research is to determine the efficacy of a sham for posterior tibial nerve stimulation (PTNS). This novel design is needed in order to have a sham treatment that is similar to the actual treatment. The PTNS is used to treat urgency and frequency in people with overactive bladder (OAB).

About this study
The overall goal of this research is to determine the efficacy of a sham for posterior tibial nerve stimulation (PTNS). This novel design is needed in order to have a sham treatment that is similar to the actual treatment. The PTNS is used to treat urgency and frequency in people with overactive bladder (OAB). Until research is done using a sham component, we are unable to ascertain if the current use of PTNS is due to a placebo effect.
Read the detailed description
Subjects will be healthy volunteers who are recruited by word of mouth. At their office visit with the Nurse Practitioner (NP), the subject's history and medication list will be reviewed.
The NP will randomize subjects into groups: one group with the PTNS on the right and sham on the left; the other group with the PTNS on the left and sham on the right. There will be a maximum of 30 subjects tested, and up to 50 people screened. The subjects will have 1 session for the testing of the PTNS vs sham that will include 15 minutes of stimulation as noted below. All participants will be blinded to the therapy they receive as described below.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Posterior Tibial Nerve DeviceDevice
Also called PTNS device, Urgent® PC
The PTNS device (Urgent® PC) is a minimally invasive neuromodulation system designed to deliver retrograde access to the sacral nerve through percutaneous electrical stimulation of the tibial nerve (PTNS). It is a combination of a stimulator and a lead set. The stimulator is a battery powered, external pulse generator and is designed, constructed, and manufactured for multiple use in conjunction with the lead set. The lead set (comprised of the lead wires, needle electrode, and alcohol pad) transfers the electrical current from the stimulator to the tibial nerve via the needle electrode. The tibial nerve travels up the leg to the sacral nerve plexus which regulates the bladder and pelvic floor function.
ShamDevice
Also called Streitberger needle
This 2- piece needle, comprised of a needle handle and blunt-tip shaft feels like a slight prick when touched to the skin. However the shaft retracts as it appears to enter the skin but the skin is not punctured. The Streitberger needle specifically activates the dorsolateral prefrontal cortex, which is associated with the placebo effect.
| Study group | Role | What they receive |
|---|---|---|
| Active Treatment Arm | Active comparator | Subjects will have their leg and foot draped to remain blinded to the test. They will be in a supine position with the knees abducted and flexed. The medial aspect of the lower extremity is palpated and a needle insertion site is identified. Between the posterior margin of the tibia and the soleus muscle, an acupuncture-like needle is inserted. An adhesive grounding pad is placed on the bottom of the foot just below the smallest toe. The needle and grounding pad are connected to the stimulator and the stimulation is increased as tolerated. Receives: Device: Posterior Tibial Nerve Device |
| Sham Arm | Sham comparator | Since subjects with the PTNS will feel foot stimulation, the sham was devised to mimic this feeling without the tibial nerve being stimulated. Again the leg and foot will be draped and out of view from the subject. The medial aspect of the lower extremity is palpated (Figure 4) and the tibial nerve site is identified approximately 5 cm cephalad from the medial malleolus. A Streitberger needle is used at the tibial nerve insertion site to simulate needle placement without puncturing the skin. The needle will be taped in place as in the PTNS procedure. The "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. Receives: Device: Sham |

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Posterior Tibial Nerve Device in people with Overactive Bladder, run by Corewell Health East at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Sep 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The objective of this study is to determine the efficacy of a sham for posterior tibial nerve stimulation (PTNS). (time frame: Prospective). 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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Sep 2007.
