| Abstract: | Study design - A longitudinal retrospective correlation study Objectives - 1) To determine the correlations among pain, disability, lumbar muscle endurance and fear-avoidance behaviour in patients with chronic low back pain. 2) To determine the predictive power of fear-avoidance behaviour on improvement in treatment outcomes following treatment. Sample - Subjects (n=178) with chronic low back pain Intervention -Active back reconditioning exercises using standardized protocol Outcome measures - Pain, disability and lumbar muscle endurance were measured at week 0, 6 and 12. Fear-avoidance behaviour was measured at week 0. Changes in pain and disability were measured at week 6 and 12. Data Analysis - 1) Pearson Correlation coefficients were calculated to determine the correlations among the outcome measures. 2) Regression analysis was employed to examine the predictive power of fear-avoidance behaviour on improvement in treatment outcomes. Results - Fair to moderate correlation was found between pain and disability (r=0.35-0.62). FABQ was correlated with pain at a weak degree (r=0.23). FABQ was correlated with disability at a fair degree (r=0.30-0.42). Lumbar muscle endurance was not associated with all other outcome measures. FABQ was inversely correlated with long-term improvement in disability at a fair degree (r=-0.35). FABQ demonstrated a significant predictive power on long-term reduction in disability following treatment, accounting for 12% of the variance in outcome. Conclusion - No strong correlations were found among pain, disability, lumbar muscle endurance and fear-avoidance behaviour, except for that between pain and disability. Treatment, therefore, should aim to address as many related aspects in the condition as possible, including physical, psychosocial and behavioural aspects in order to enhance treatment success in the management of chronic low back pain. Fear avoidance behaviour significantly predicted long-term reduction in disability following treatment, accounting for 12% of the variance in outcome. |
