One therapy concept. Several different approaches.

Tibial nerve stimulation (TNS) is receiving increasing attention worldwide as a treatment for overactive bladder (OAB) symptoms.

Published studies suggest that approximately one-half to two-thirds of patients who try TNS experience meaningful improvement. However, TNS does not work for everyone.

Several different methods stimulate the same tibial nerve. They differ in how stimulation is delivered, cost, convenience, physician involvement, regulatory status, and history.

History: TNS therapies have evolved rapidly over the last two decades, compared with some of the approaches previously listed, which have antecedents dating back centuries.

If your physician agrees there are no contraindications or reasons preventing your TNS trial, will one TNS approach fit your circumstances better than another?

If you've reached this fifth category of OAB therapy alternatives, your list of therapies to discuss with your physician is probably not yet complete.

Before comparing the TNS therapies, general observations worth considering are:

1. Commercial and clinical interest in TNS therapy for OAB symptoms is growing. TNS clearly works for some patients.
2. Patients may reasonably ask if success with one approach predicts success with another.
3. We are unaware of statistical evidence, but some anecdotes suggest it may.
4. If you have no contraindications to TNS, deciding whether to try a TNS alternative is a knowledge-based decision.
5. Knowing whether the therapy mitigates your OAB symptoms requires experience.
6. If you want to switch to another TNS therapy later, try it. If the results are unsatisfactory, you may consider returning to a previously successful approach.
7. Whether patients can always successfully migrate between TNS alternatives is unknown. The author successfully migrated from PTNS to TTNS.
8. Much remains to be learned about TNS. Every patient's experience contributes to that understanding.

Tibial Nerve Stimulation (TNS) Alternatives

Vivally – Big news: In 2024, the FDA cleared its first surface-electrode TNS device. Its Velcro ankle cuff places surface electrodes similar to PTNS and TTNS. According to the manufacturer, integrated electronics verify stimulation during treatment. It is expensive (Cost: $ Thousands).

Revi, an implantable neuromodulation system, is an FDA-cleared therapy. It wirelessly stimulates the Tibial nerve. (Think of the way an electric toothbrush recharges through its base - Cost: $ Tens of Thousands).

PTNS (Percutaneous TNS) - A clinician places a very thin acupuncture needle in the correct anatomical region of the lower leg and then confirms that electrical stimulation is likely to be successful by observing your response. Annual costs may exceed $1,500, with patient copays often exceeding $500/A. Access and scheduling are issues, but it is the most widely used, FDA-cleared, TNS approach in the U.S. (Cost: < $1000/A up to a $ few thousand per annum without insurance.)

TTNS (Transcutaneous TNS) has been extensively studied and is commonly used in many countries outside the U.S. It uses surface electrodes that can be placed in the lower leg/foot similar to PTNS. Published studies support its efficacy. Costs: device ~$50; at-home treatment <$1. A few Americans have used this therapy, but it is not FDA-cleared. (Cost < $100/A.)

This next chart summarizes the major differences among the current TNS alternatives at the end of 2025. It compares the available TNS approaches to facilitate your decision on which, if any, to discuss with your physician. You should confirm the information is current before making a final treatment decision.
