Collision avoidance behaviours in chronic non-specific low back pain participants: A prospective cohort study.

Objective: Chronic non-specific low back pain (cNSLBP) is a leading cause of disability, influenced by bio-psycho-social factors. However, its impact on everyday activities such as navigating streets and interacting with other pedestrians remains underexplored. This study aimed to assess the effect of cNSLBP on perceptual-motor processes in a pedestrian crossing task, focusing on 1) collision avoidance behaviours, 2) the walker's role in avoiding collisions, and 3) the influence of pain perception.
