Accessory Movements and Associated Factors During Active Cervical Range of Motion

This project aims to quantify accessory movements that occur during cervical range of motion (ROM) assessment in young adults and to examine their relationship with functional and psychological factors. Although cervical ROM is widely used in clinical practice, accurate measurement is challenged by the complex anatomy of the cervical spine and coupled movements, which may alter true motion values. Despite their clinical relevance, accessory movements have been largely overlooked in both research and routine assessment. This cross-sectional observational study will include volunteers aged 18-30 years, recruited between January and August 2025 following ethical approval. Individuals with cervical trauma or surgery, neurological disease, recent treatment, musculoskeletal injury, or medications affecting movement will be excluded. Accessory movements will be measured using the CROM device while participants perform flexion-extension, lateral flexion, and rotation, maintaining end-range for 20 seconds to record primary and accessory motions. Clinical outcomes will include cervical disability (Neck Disability Index), pain intensity (Visual Analog Scale), cervical mechanosensitivity (pressure algometry at the upper trapezius and C2-C7 regions), psychological status (Depression, Anxiety, Stress Scale-21), and sleep quality (Pittsburgh Sleep Quality Index).
