Central Sensitization and Clinical Parameters in Chronic Neck Pain

Correlation of Central Sensitization With Pain, Pain Catastrophizing, Disability, Sleep Quality, and Jaw Function in Patients With Chronic Neck Pain: A Retrospective, Cross-Sectional Study

This study is a retrospective, cross-sectional observational study that assesses the correlations among central sensitization, pain, psychosocial factors, and temporomandibular function in patients with chronic neck pain. It underscores the importance of the biopsychosocial model in clinical practice and aims to improve understanding of central mechanisms in treatment planning. treatment planning.

Chronic neck pain is a widespread health issue globally that negatively impacts quality of life. In some patients, pain cannot be explained solely by tissue damage; increased sensitivity of the central nervous system (central sensitization) may contribute to the persistence of pain.

The aim of this study is to explore the relationship between the level of central sensitization and the following parameters in individuals with chronic neck pain:

• Pain intensity
• Pressure pain threshold
• Pain catastrophizing level
• Neck-related disability
• Sleep quality
• Jaw function

The study has a retrospective, cross-sectional design. Records of patients previously evaluated in the clinic will be analyzed. No new interventions will be conducted on participants. The study is observational in nature.

This research aims to:

• Enhance understanding of the clinical significance of central sensitization in chronic neck pain
• Contribute to the development of multidisciplinary treatment strategies
• Support the management of patients through more personalized treatment plans.

Patients with a Pain Catastrophizing Scale (PCS) score greater than 30.

Patients with a Central Sensitization Inventory (CSI) score greater than 30.

Patients who have not received physiotherapy or manual therapy in the past 3 months.

Exclusion Criteria:

Patients with a history of whiplash injury or fracture.

Individuals with unstable neurological findings.

Presence of cervical pathology such as herniation or nerve root compression.
