AbstractPatients with recurrent or persistent low back pain (LBP) and disability represent a formidable challenge to physical therapists. Classic models of disease and pain mechanisms do not adequately explain the commonly observed discrepancies between the extent of pathology and reported pain, or the level of pain and disability. Research over the past decade that considers the interactive role of biological, environmental, and psychological processes in pain and disability has supported the involvement of a number of biobehavioral factors in these conditions. Physical therapists and other health care providers have become more aware of these factors and their impact on the evaluation, treatment, and management of LBP. Despite this recognition, little information is available that translates the implications of this research to direct care within physical therapy practice. The purposes of this article are (1) to provide an operational definition of biobehavioral factors; (2) to review the role of these factors in the clinical presentation of LBP, functional limitation, and disability; (3) to identify commonly used approaches for their recognition and quantification; (4) to illustrate how an understanding of biobehavioral factors can assist the physical therapist in evaluation and treatment of patients with LBP; and (5) to identify certain gaps in current knowledge of the role of biobehavioral factors and their application in physical therapy. Given the central role assumed by many physical therapists in the management of LBP, acknowledging and addressing these factors in clinical practice should assist in the prevention of chronic LBP and disability, as well as potentially improve physical therapy interventions and management.
