Could simple posture exercises reshape how jaw and neck muscles work?
NCT ID NCT07780396
First seen Aug 21, 2026 · Last updated Aug 21, 2026
Summary
This trial explores whether a structured 10-week exercise program can alter the electrical activity of jaw and neck muscles in people with forward head posture—a common condition where the head sits too far forward. Participants aged 18 to 30 with this posture but no neck pain will be randomly assigned to either a specific exercise routine or general exercises. Researchers will measure muscle activity and head posture before and after the program to see if the targeted exercises make a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A structured 10-week exercise program combining strengthening and stretching exercises for neck and shoulder muscles.
- What this could lead to
- If effective, this exercise program could offer a simple, drug-free way to improve posture and potentially reduce the risk of future neck or jaw problems.
- What could go wrong
- This is a small, early-stage trial, and the results may not apply to everyone. The exercises may not produce meaningful changes in muscle activity or posture.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 1\. Participants aged 18- 30 years. 2. Presence of forward head posture, defined as CVA of less than 50° with no symptoms of neck pain \[18, 19\]. 3. No treatment for TMD or cervical symptoms (e.g., medication, physical therapy, or intra-articular injection) within the previous 2 weeks. Exclusion Criteria: * 1\. Current or previous diagnosis of temporomandibular disorder (TMD), or the presence of TMD-related signs or symptoms (e.g., joint sounds, restricted mouth opening, or orofacial pain) during screening. 2\. History of TMJ subluxation or dislocation that could interfere with mouth opening. 3\. History of recent head or neck trauma. 4. Angle Class II or Class III malocclusion. 5. Postural abnormalities secondary to structural spinal deformities (e.g., scoliosis or kyphosis), rheumatic diseases, or other medical conditions affecting posture. 6\. Missing posterior teeth, recent orthodontic treatment (within the previous 12 months), or dental restorations that altered occlusion.
