sychological factors are commonly used to explain the development and maintenance of chronic low back pain (LBP). 38,39 In fact, individual studies suggest that psychological factors are stronger than physical and demographic factors for predicting LBP outcomes. 8,20 This clinical commentary focuses on the fear-avoidance model of musculoskeletal pain (FAM), which was reviewed by 29 Briefly, the FAM proposes that the primary affective and cognitive components influencing pain perception are anxiety, pain-related fear (including fear of movement and reinjury), physical (limitations in physical performance and disuse syndrome), and societal (chronic disability) consequences. 6,27,32,48 The FAM was selected as the focus of this manuscript, because the model appears to have clinical relevance for patients with LBP. Specifically, previous studies suggest that questionnaires based on the FAM accurately identify poor prognosis for patients with LBP.
