What is Implicit Evaluations and Physiological Threat Responses in People with Persistent Low Back Pain and Fear of Bending about?

## Abstract ## Background and aims Pain and protective behaviour are dependent on implicit evaluations of danger to the body. However, current assessment of perceived danger relies on self-report, on information of which the person is aware and willing to disclose. To overcome this limitation, attempts have been made to investigate implicit evaluation of movement-related threatening images in people with persistent low back pain (PLBP) and pain-related fear. Lack of specificity of the sample and stimuli limited those explorations. This study investigated implicit evaluations and physiological responses to images of tasks commonly reported as threatening by people with PLBP: bending and lifting. We hypothesized that people who differ in self-reported fear of bending with a flexed lumbar spine (__fear of bending__) would also differ in implicit evaluations and physiological responses. ## Methods This study used a convenience sample of 44 people (54% female) with PLBP, who differed in selfreported__fear of bending__. Participants completed a picture-viewing paradigm with pleasant, neutral and unpleasant images, and images of people bending and lifting with a flexed lumbar spine (‘roun
