Could your neck be making your jaw pain worse?
NCT ID NCT07666360
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is looking at how problems with the jaw, neck, and head position relate to the severity of temporomandibular disorder (TMD), a condition that causes jaw pain and dysfunction. Researchers will assess 60 adults using questionnaires and physical measurements. The goal is to find which factors best predict how severe TMD symptoms are, which could help guide future treatments.
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 key factors that predict TMD severity, leading to more targeted treatments.
- What could go wrong
- This is an observational study with only 60 participants, so findings may not apply to everyone with TMD. It does not test a treatment.
