Back ground: Chronic neck pain is one of the most common musculoskeletal pain conditions experienced by many people during their lives. Due to increased use of Tech devices & modern life style, forward head posture & resultant neck pain becomes quiet common. Although patients with neck pain are managed predominantly as musculoskeletal patients, there are indications that they also have poor pulmonary function as limited movement of the neck muscles can result in impaired chest movements. The aim of this study was to examine whether patients with chronic neck pain have impaired pulmonary measures. Methodology: A cross sectional observational study was conducted to evaluate pulmonary function measures in patients with chronic neck pain.100 subjects included dividing them into 2 groups. Group A: Patients with Chronic Neck Pain. Group B: Age & sex matched healthy individuals. Written Consent was taken from the subjects and the subjects were made to understand the purpose of the study. Spirometry was performed for all the subjects. Forced vital capacities (FVC), forced expiratory volume in the first second of FVC (FEV1), ratio of FEV1/FVC and maximum voluntary ventilation (MVV) were recorded. Neck Disability Index (NDI), Numeric Pain Rating Scale (NPRS) for pain & Craniocervical Angle (CCA) had also been considered for both the groups. Results: Data analysis was done using Microsoft office Excel. The results showed that patients with chronic neck pain yielded significantly reduced FVC, FEV1 and maximum voluntary ventilation (P < 0.005), but FEV1/FVC ratio were not affected significantly (P > 0.5). Craniocervical Angle & Pain Intensity was found to be significantly correlated with respiratory function. CONCLUSION: Patients with chronic neck pain do not have optimal pulmonary function. Cervical spine muscle dysfunction in parallel with pain intensity and kinesiophobia are factors that are associated mainly with this respiratory dysfunction.
