Multimodal Intervention in Patients With Non-specific Chronic Low Back Pain: the HEALTHY BACK Project

Low back pain is one of the most common health problems seen in the primary care. Chronic low back pain is localized between the inferior limit of the ribs and the sacral region, and persist more than 12 weeks. In most cases, it is attributed to a non-specific cause and classified as non-specific chronic low back pain (NSCLBP). No previous study has included a multimodal supervised program in patients with NSCLBP. The primary aim of this study is to determine the effectiveness of exercise + behaviour change + education + mindfulness programs (intervention 1) and an intervention including intervention 1 following functional resistance training (Intervention 2) on endogenous pain modulation, disability, muscle strength/endurance, quality of life, gait parameters, levels of physical activity, sedentary behaviour and psychological health in patients with NSCLBP.
