This study aims to investigate the mediating role of kinesiophobia in the relationship between pain intensity and disability in individuals with chronic neck pain. Chronic neck pain is a multidimensional clinical condition influenced not only by biological factors but also by psychological components such as fear of movement. Understanding the mechanisms underlying disability may contribute to more targeted rehabilitation strategies. Participants with chronic neck pain lasting at least three months will be assessed using validated self-report questionnaires measuring pain intensity, kinesiophobia, disability, and physical activity levels.

Chronic neck pain is a common musculoskeletal disorder associated with significant functional limitations and reduced quality of life. While pain intensity is considered an important determinant of disability, it does not fully explain variations in functional outcomes among individuals. Psychological factors, particularly kinesiophobia, may influence the relationship between pain and disability through fear-avoidance mechanisms.

The purpose of this cross-sectional observational study is to examine whether kinesiophobia mediates the relationship between pain intensity and disability in individuals with chronic neck pain. Disability will be assessed in a multidimensional framework including neck-related and upper extremity functional limitations. Findings from this study may provide clinical implications for rehabilitation approaches targeting psychological components of chronic pain.
