Why Fear of Movement Can Become More Disabling Than the Original Injury

Two Very Different Responses to the Same Injury

After an acute musculoskeletal injury, people tend to follow one of two broad paths. Some interpret the pain as a normal, expected part of recovery, gradually return to movement despite some discomfort, and recover well. Others interpret the same pain as a sign of serious ongoing damage, avoid movement out of fear, and go on to develop much greater disability — frequently disproportionate to the severity of the original injury.

The Fear-Avoidance Model

This divergence is formally described by the fear-avoidance model, an influential and extensively validated framework proposing that catastrophic interpretation of pain drives pain-related fear, which in turn drives avoidance of movement and activity. Over time, this avoidance leads to physical deconditioning, increased disability and, often, low mood — all of which feed back to further reinforce the fear and avoidance, creating a self-perpetuating cycle (Vlaeyen & Linton, 2000).

Why Graded Exposure Is the Antidote

Because the cycle is maintained largely by avoidance rather than by the original tissue injury, effective treatment typically centres on graded, carefully progressed exposure to movements and activities the person has come to fear — directly challenging the catastrophic beliefs driving the avoidance, rather than simply treating the original injured tissue in isolation.
