Background: However, the prevalence of chronic low back pain is high; the relation between pain perception and poor functional performance among these patients is still unclear. Therefore, this study aimed to investigate the relation between cognitive awareness and functional performance in patients with chronic low back pain.
Methods: 120 patients were enrolled in the study as one group. All patients were diagnosed with chronic nonspecific low back pain (CNLBP) and their mean Age was 32.43 ± 5.77 years. The Visual Analog Scale was used to assess pain intensity, fair avoidance and believe questionnaire was used to assess the social and behavioral aspects of the subject and Oswestry disability index was used to assess the functional performance level.
Statistics: Pearson correlation coefficient was carried-out to examine the correlation among Oswestry disability index, VAS, fair avoidance and believe questionnaire/work, as well as fair avoidance and believe questionnaire/ life. The variables with a significant correlation with Oswestry disability index findings were identified using multiple linear regressions. A significance level of p < 0.05 was established for statistical testing.
Results: Statistical analysis revealed that the Oswestry disability index was strongly correlated with FABQW (r = 0.915, p = 0.001), FABQPA (r = 0.866, p = 0.001), and VAS (r = 0.891, p = 0.001). The VAS had a strong positive correlation with FABQW (r = 0.951, p = 0.001) and with FABQPA (r = 0.915, p = 0.001). Conclusion: Our study reflects the probable impact of CNLBP as an underlying cause of altered cognitive behavior and consequently reduced functional performance.
