A cross-sectional study of associations between kinesiophobia, pain, disability, and quality of life in patients with chronic low back pain

Background: Low back pain is a significant health problem condition due to high prevalence among the general population. Emotions and physical factors are believed to play a role in chronic low back pain. Kinesiophobia is one of the most extreme forms of fear of pain due to movement or re-injury. The purpose of this study was to investigate the association between kinesiophobia and pain intensity, disability and quality of life in people with chronic low back pain. Methods: The study included 132 individuals with chronic back pain, with ages between 18 and 65 years old. Kinesiophobia was assessed using the Tampa Scale of Kinesiophobia, pain intensity was measured using the Numeric Rating Scale with a cut-off more than 3 for inclusion in the study, disability was assessed using the Roland Morris questionnaire, quality of pain was assessed using the McGill questionnaire, and quality of life was assessed using the Quality of Life questionnaire SF-36. Results: The results are statistically significant, but with weak associations were found between kinesiophobia and pain intensity (r = 0.187), quality of pain (sensory, r= 0.266; affective, r= - 0.174; and total r= 0.275), disability (r = 0.399) and physical quality of life (emotional r= - 0.414). Conclusion: Kinesiophobia is an important outcome to assess in patients with chronic low back pain. The results suggest that correlations between kinesiophobia and disability and quality of life are statistically significant.
