NCT ID NCT07468786
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study will use ultrasound to measure the thickness of the masseter (jaw) muscle in 90 adults—45 with chronic neck pain and 45 healthy. The goal is to see if the muscle is different in those with neck pain and how it relates to pain intensity and disability. No treatment is given; it is purely an observational study to gather knowledge.
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 help identify a measurable physical difference in neck pain patients, potentially guiding future diagnostic or treatment approaches.
- What could go wrong
- This is an early observational study with no treatment being tested. It only looks at a possible link, not a cause or cure, so results may not lead to any direct benefit.
