The purpose of the guideline is to provide evidence-based recommendations on nonsurgical interventions for chronic primary LBP (CPLBP) in adults, including older people, that can be delivered in primary and community care settings to improve CPLBP-related health and well-being outcomes. For this reason, the guideline does not consider interventions typically delivered in secondary or tertiary care settings (e.g. surgical or other invasive procedures) or workplace interventions.
