Low back pain (LBP) is the leading cause of years lived with disability [Several factors can increase the risk of experiencing LBP, including physical (e.g., regular lifting), psychological (e.g., depression), and poor general health (e.g., sleep problems) [The association between subjective (i.e., pain) and objective measures (i.e., endurance and strength of the trunk muscles) in individuals with CLBP [Therefore, this clinical trial will test the effectiveness of an m-health-based self-managed program based on core strengthening exercises plus health education, compared to an m-health education only, on physical and perceptual outcomes. Considering that several studies demonstrate the effectiveness of health education in the clinical outcomes of patients with CLBP, we choose for an active comparator group intending to reach the principle of equipoise. We hypothesize that the effects of an m-health self-managed program based on core strengthening exercises plus health education will be superior on co-primary and secondary outcomes, compared to education health program.
