Behavioural activation and inhibition systems in relation to pain intensity and duration in a sample of people experiencing chronic musculoskeletal pain.
There is potential clinical utility in tailoring patients' pain management based on behavioural tendencies. Previous work demonstrates a link between behavioural approach/inhibition and pain experience. ⋯ Neither BIS nor BAS significantly related to, or predicted pain intensity or duration. No differences in activation and inhibition tendencies were evident between high and low pain intensity groups. This study provides further support for the inter-relationships between fear-avoidance beliefs, kinesiophobia, disability and pain duration and intensity. No explicit support for behavioural links to pain were shown, however, this may be due to the measurement instrument rather than an invalid theory.

Randomized Controlled Trial Comparative StudyChanges in pressure pain threshold and temporal summation in rapid responders and non-rapid responders after lumbar spinal manipulation and sham: A secondary analysis in adults with low back pain.
People with LBP who experience rapid improvement in symptoms after spinal manipulative therapy (SMT) are more likely to experience better longer-term outcomes compared to those who don't improve rapidly. It is unknown if short-term hypoalgesia after SMT could be a relevant finding in rapid responders. ⋯ Hypoalgesia in shoulder PPT occurred transiently in the rapid responders compared to the non-rapid responders. This may or may not contribute to symptomatic improvement after SMT or sham in adults with LBP, and may be a spurious finding. Short-term changes in TS do not appear to be related to changes in LBP.
