Could a gentle leg tingle replace pain pills during bladder botox?

NCT ID NCT07707791

First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time

Summary

This study tests whether applying mild electrical pulses (TENS) to the shins can reduce pain and anxiety in people receiving Botox injections into the bladder for overactive bladder. Participants are randomly assigned to receive either active TENS or a sham device during the injection. Neither the patient nor the doctor knows which group they are in. The goal is to see if this simple, drug-free approach makes the procedure more comfortable.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
transcutaneous electrical nerve stimulation (TENS) applied to the pretibial area
What this could lead to
If it works, this could offer a simple, drug-free way to reduce pain and anxiety during a common office procedure for overactive bladder.
What could go wrong
This is a small, early-stage trial with only 68 participants, and the placebo effect may be strong. TENS may not provide meaningful relief for everyone.
