Jaw pain linked to weaker neck muscles in young adults, study finds
NCT ID NCT07407127
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 60 university students aged 18-25 to see if those with temporomandibular joint disorder (TMD) have different neck muscle endurance and pain sensitivity compared to healthy students. Researchers measured how long students could hold neck exercises and how much pressure caused pain in jaw and neck muscles. The goal was to better understand how TMD affects the body, not to test a treatment.
