Primary outcome for this project will be quantitative pain levels, using the VAS. Monitoring of medication use is expected to support this outcome. Further primary outcome centering on functionality scores will focus on the Oswestry and SF 36. The SF36 results can be expected to be a useful adjunct in the assessment of patients with low back pain when combined with disease-specific questionnaires (3). All other measures will be used descriptively and as explanatory variables.
