Effect of Progressive Neck Motor Control Exercises on Temporomandibular Joint Dysfunction

This study is testing whether specific neck muscle exercises can help relieve jaw pain and dysfunction (a condition called temporomandibular joint dysfunction, or TMD). TMD causes pain in the jaw joint and the muscles that control jaw movement, and researchers want to see if targeting neck muscles through progressive exercises can reduce these symptoms. **You may be eligible if...** - You are 18 to 55 years old - You have had jaw joint complaints for at least 3 months - A dentist has diagnosed you with temporomandibular joint dysfunction through clinical and imaging evaluation - You have neck pain rated 3 or higher on a 0–10 pain scale **You may NOT be eligible if...** - You have cognitive problems - You currently wear a dental splint - You used painkillers or muscle relaxants for your jaw in the past week - You have a systemic joint or muscle disease (e.g., fibromyalgia, rheumatoid arthritis) - You have a serious systemic illness - You have a neurological disorder (e.g., trigeminal neuralgia) - You are pregnant or breastfeeding - You received treatment for jaw or facial muscle pain in the last 3 months - You had surgery or trauma to your neck or jaw joint Talk to your doctor to see if this trial is right for you.
