Reduction of fear of movement-related pain and pain-related anxiety: an associative learning approach using a voluntary movement paradigm

Meulders, Ann, Vlaeyen, Johan W.S.·2012·Pain

Abstract

The fear-avoidance model advances fear of pain as a key factor in the origins of chronic pain disability. Initial evidence in those with chronic back pain reveals that exposure therapy reduces fear levels, disability, and pain. Despite the success of exposure in the clinic, fundamental research about its underlying mechanisms lags behind. Using a conditioning paradigm with movements as conditioned stimuli (CS) and a painful shock as unconditioned stimuli (US), we investigated the extinction of experimental fear of movement-related pain and pain-related anxiety (respectively induced by predictable and unpredictable pain). Dependent measures were self-reported fear and eyeblink startle. During acquisition, all groups received both predictable and unpredictable training. In the predictable context, one movement (CS+) was consistently followed by the shock-US, but another movement was not (CS-). In the unpredictable context, joystick movements never signaled the shock-US; shock-US were delivered during the intertrial interval (ITI). During extinction, the extinction group continued training in the predictable context but the CS+ movement was no longer reinforced; the context exposure group continued training in the unpredictable context but ITI shock-US were omitted. The control group continued training after the acquisition reinforcement scheme. Results revealed that fear ratings for the CS+ were extinguished in the extinction group but not in the control group. Interestingly, omitting the ITI shocks not only reduced ITI startle responses in the context exposure group compared with the control group, but also reduced the fear ratings and startle responses elicited by the unpredictable CS. The clinical implications of these findings are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
