Objective: To compare the effectiveness of supervised physical therapy program versus non-supervised on pain, functionality, fear of movement and quality of life in patients with non-specific chronic low back pain. Design: A randomized double-blind clinical trial. Setting: Clinical outpatient unit; home. Subjects: A total of 64 participants with non-specific chronic low back pain were randomized into either supervised exercise group ( n = 32) or non-supervised home exercise group ( n = 32). Interventions: The supervised group was treated with therapy exercises (strengthen lumbopelvic musculature), while the non-supervised received an informative session of the exercises, which were performed un-supervised at home. Both groups received three weekly sessions for eight weeks. Main Measures: Pain, disability, fear of movement, quality of life, trunk muscle endurance and trunk anteflexion motion were assessed at baseline, two, and six months of follow-up. Results: Although analysis of variance (ANOVA) test showed statistically significant differences between groups for pain ( P = 0.028; supervised: 2.5 ± 2.1; non-supervised: 3.5 ± 1.5) and disability for Roland–Morris Disability Questionnaire ( P = 0.004; supervised: 3.1 ± 2.2; non-supervised: 5.1 ± 3.0) and for Oswestry Disability Index ( P = 0.034; supervised: 14.5 ± 7.1; non-supervised: 19.2 ± 10.0) at 8 weeks immediately posttreatment, there were no differences between the groups in patient-rated pain, functionality, fear of movement and quality of life at six months of follow-up. Conclusion: Patients with chronic low back pain who received supervised exercise showed more improvement in both the short and long term in all patient-rated outcomes over the non-supervised group, but the differences were small and not clinically significant.
