Abstract

Non-specific chronic low back pain is a major health problem and socio-economic order responsible for a high of absenteeism from work and reduced functional performance. The practice of supervised exercise and cognitive behavioral therapy is one of the few treatments recommended, since they have positive results in the recovery of this symptom. However, there is little evidence of the effectiveness of one over the other. OBJECTIVE: To compare the effect of cognitive behavioral therapy and exercises (gradual activity) versus supervised exercise program in patients with Non-specific chronic low back pain. METHOD: Sixty-six subjects will be randomized into two groups: Group Behavior Therapy - Graded Activity (AG) and Supervised Group Exercises (ES). The groups will be treated in two weekly sessions lasting about one hour for six weeks, totaling 12 sessions. The primary clinical outcomes will be pain, assessed using the numerical pain scale and McGill Pain Questionnaire and disability assessed with Roland Morris Disability Questionnaire. Secondary outcomes will be measured with the overall perception of the scale of global perceived effect, quality of life using the Short-Form Health Survey questionnaire (SF-36) and return to work. The outcomes will be obtained at follow-up appointments at 6 weeks, 3 and 6 months after randomization. Data will be collected by a blinded assessor who also has made the allocation of patients in both groups. STATISTICS Statistical tests are applied in the software SigmaStat 3.5. Testing will take place one-way ANOVA (baseline), two-factor ANOVA (post intervention) and multiple comparison test post-hoc Tukey for the data considered normal. For non-normal data will be applied the Wilcoxon Signed Rank Test. The significance level ± d 0.05.Key - words: Low back pain, Exercise therapy, clinical trial (AU)
