Brain areas involved in anticipation of clinically-relevant pain in low back pain populations with high levels of pain behaviour

The purpose of this study was to identify neural correlates of pain anticipation in people with non-specific low back pain (NSLBP) that correlated with pain-related distress and disability, thus providing evidence for mechanisms underlying pain behaviour in this population. Thirty NSLBP sufferers, with either high levels of pain behaviour (WS-H) or low levels (WS-L) based on Waddell Signs (WS), were scanned with functional Magnetic Resonance Imaging (fMRI) whilst a straight-leg raise (of the side deemed to cause moderate pain in the lower back) was performed.
