Hands-On therapy vs. injection: which eases tailbone pain best?
NCT ID NCT07642167
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two treatments for chronic tailbone pain (coccygodynia) in 100 adults. One group received osteopathic manual therapy—gentle hands-on techniques to mobilize the tailbone and relax muscles—over 6 weeks. The other group got a nerve block injection guided by X-ray. Researchers measured pain, disability, and quality of life before treatment and at 3 weeks and 3 months after. The goal was to see which approach provides better and longer-lasting relief.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could show which treatment—manual therapy or a nerve block—works better for long-lasting tailbone pain, helping doctors choose the best option.
- What could go wrong
- This is a small, completed trial with 100 people. Results may not apply to everyone, and neither treatment may prove clearly superior.
