PURPOSE: To identify clinical and psychosocial risk factors at baseline influencing disability and pain at 1 year in LBP patients sick-listed 3 to 16 weeks, and to look for differences between non- specific LBP and radiculopathy. STUDY DESIGN: Cohort study with 1-year follow-up based on a randomized clinical trial. OUTCOME MEASURES: Disability and change of disability, pain and change in pain at 1 year. METHODS: In a randomized clinical study evaluating multidisciplinary versus brief intervention, 325 patients were followed for 1 year. At baseline, they completed a questionnaire and went through a clinical low back examination, including measure of forward flexion and side flexion as well as tender point ex- amination, a method to estimate diffuse tenderness. Furthermore, degenerative changes on plain X-rays of the lumbar spine were quantified, and sciatica was investigated by magnetic resonance imaging. RESULTS: Radiculopathy was verified by magnetic resonance imaging in 111 (34%) patients. At 1 year, questions of disability in daily life activities and pain were answered by 60% and 67%, respectively. The intensity of backtleg pain and disability was closely correlated. Statistically significant predictors for both disability and backtleg pain at 1 year were intensity of backtleg pain, worrying and health anxiety, many tender points, and little or moderate exercise in leisure time. Two additional risk factors were identified in patients with radiculopathy: older age and 憫Adrinking alcohol less than once per month.’’ Furthe
