Abstract |
Purpose: Chronic neck pain is associated with respiratory dysfunction, affecting pulmonary function and respiratory
muscle strength. This study aimed to investigate the relationship among chronic neck pain, pulmonary function, and
respiratory muscle strength in adults. Methods: Pulmonary function, including forced vital capacity (FVC), forced
expiratory volume in 1 s (FEV₁), and FEV₁/FVC ratio, was assessed by spirometry. The respiratory muscle strength was
measured based on the maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). The relationship
among chronic neck pain, pulmonary function, and respiratory muscle strength was examined by Pearson correlation
analysis. Results: Chronic neck pain showed a significant negative correlation with FVC, FEV₁, and MEP, whereas MIP
demonstrated a nonsignificant negative relationship. Conclusion: Chronic neck pain contributes to the reduction in
pulmonary function and respiratory muscle strength, particularly MEP. These results indicate the need for pulmonary
function assessment and interventions to improve the respiratory function of patients with chronic neck pain. |
