Abstract

To investigate the ability of different physical activity domains, measured by objective and subjective instruments, in predicting clinical outcomes in chronic non-specific low back pain. Material and methods: Study design was a longitudinal cohort with 6 months follow-up. Sample size was of 179 participants with chronic non-specific low back pain. In the first evaluation, the following data were collected: anthropometric/demographic data; pain duration and intensity (Numerical Rating Scale); functional disability (Roland Morris Disability Questionnaire); fear of movement (Tampa Scale for Kinesiophobia); depression (Beck Depression Inventory) and physical activity levels measured by accelerometer (time spend in light, moderate/ vigorous physical activity, steps per day, Counts per minutes) and by Baecke questionnaire for the evaluation of habitual physical activity (occupational physical activities, leisure and locomotion physical activities and physical exercise). After 6 months patients were evaluated according to pain intensity and functional disability. Multivariate regression analysis was used to investigate the physical activity domains association with pain and disability outcomes. Results: A total of 179 participants with chronic non-specific low back pain were initially evaluated, of those, 150 participants wore accelerometer correctly in the initial evaluation. Results showed occupational physical activity, measured by Baecke questionnaire for the evaluation of habitual physical activity, had significant association with disability even though analysis had been adjusted for covariates presence. Which means that individuals who reported higher occupational physical activity levels showed higher disability levels (β: 2.94; 95% CI 1.08; 4.79). The final regression model even included the age, pain duration, depression and initial disability, explained 23.2% of disability 6 months follow-up variance. Conclusion: Among physical activity domains investigated in the present study, occupational physical activity showed to be the only domain able to predict worsening disability after 6 months. (AU)
