This group consists of 25 individuals diagnosed with chronic migraine. They will undergo cervical joint repositioning error assessment in different head positions.

This group consists of 25 age-matched healthy controls without a history of migraine. They will undergo the same cervical joint repositioning error assessment in different head positions.

The cervical joint repositioning error assessment is a non-invasive diagnostic test used to measure the ability of an individual to accurately reproduce a specific head position in different orientations (flexion, neutral position, 50% range of motion of left rotation, and 50% range of motion of right rotation). Participants in both the chronic migraine group and the control group will undergo this assessment using a digital inclinometer. The primary outcome of this study is the difference between the initial and repositioned cervical joint angles, measured in degrees.
