Management of non-specific low back pain in primary care - A systematic overview of recommendations from international evidence-based guidelines.

Aim: Systematic identification, characterization and analysis of recommendations concerning the diagnosis and treatment of non-specific low back pain (LBP) in primary care provided in international evidence-based guidelines from high-income countries.

Background: LBP is one of the most common reasons for consulting a primary care physician and its prevalence is higher in high-income than in middle- or low-income countries. The majority of LBP is non-specific and treatment recommendations are not often based on high-quality and patient-oriented evidence.
