Tongue Pressure in Middle-Aged and Elderly Individuals With Chronic Cervical Pain

This study is measuring tongue pressure in middle-aged and older adults with chronic neck pain to explore whether neck pain is linked to changes in tongue strength, which may reflect how the deep neck muscles function. **You may be eligible if...** - You are between 50 and 65 years old - You have chronic neck pain (lasting at least 3 months within the past year) caused by neck movement or prolonged posture, with an average pain score of at least 3/10 over the past two weeks - OR you are a healthy adult matching the age, gender, and BMI of participants with neck pain (control group) **You may NOT be eligible if...** - You have a neurological condition that may affect tongue strength (e.g., stroke, Parkinson's disease) - You took anti-inflammatory or pain medications within 48 hours before testing - You have had no neck pain in the past 6 months (for the pain group only) Talk to your doctor to see if this trial is right for you.
