Unraveling the role of fear and avoidance behavior in chronic musculoskeletal pain: from theory to physical therapy clinical practice

BACKGROUND: Protective behaviors in the context of pain fostered by fear are helpful in acute traumatic pain to enable a person to protect their body from further injury and promote healing in the short term. However, protective behavior that is ongoing in the absence of tissue damage may contribute to the persistence of disability in people with musculoskeletal pain. Current evidence highlights the importance of addressing pain-related fear, fear of movement-related pain, and avoidance behavior in the management of people with chronic musculoskeletal pain. But, physical therapists find it challenging to make sense of and implement the evidence in their clinical practice. This issue partly stems from the pervasiveness of the biomedical model, which fails to address important psychological factors such as fear of movement-related pain and avoidance behavior and their role in chronic musculoskeletal pain. Despite a wider acceptance of the biopsychosocial model of care, physical therapists lack confidence and guidance on how to implement this model into practice. OBJECTIVE: The aims of this masterclass are twofold: (1) to describe how the concepts/theory of fear learning can be applied in physical therapy practice for people with chronic musculoskeletal pain, (2) to illustrate the implementation of these concepts in clinical practice using an example of the management of a person with a chronic musculoskeletal pain condition. DISCUSSION: We discuss how clinicians may identify and target fear of movement-related pain and avoidance behavior in clinical practice, with examples of how to understand and manage individuals with chronic musculoskeletal pain using an associative learning and behavioral framework.
