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.

Randomized Controlled Trial Comparative StudyNo difference in pressure pain threshold and temporal summation after lumbar spinal manipulation compared to sham: A randomised controlled trial in adults with low back pain.
Changes in quantitative sensory tests have been observed after spinal manipulative therapy (SMT), particularly in pressure pain thresholds (PPT) and temporal summation (TS). However, a recent systematic review comparing SMT to sham found no significant difference in PPT in patients with musculoskeletal pain. The sham-controlled studies were generally low quality, and conclusions about other quantitative sensory tests could not be made. ⋯ Our results suggest that lumbar SMT does not have a short-term hypoalgesic effect, as measured with PPT and TS, when compared to sham manipulation in people with low back pain.

Randomized Controlled TrialAssociation between sympathoexcitatory changes and symptomatic improvement following cervical mobilisations in participants with neck pain. A double blind placebo controlled trial.
sympathoexcitation observed with passive cervical mobilisations may imply activation of an endogenous pain inhibition system resulting in hypoalgesia. However, research is mostly in asymptomatic participants and there is very limited evidence of a relationship between sympathoexcitation and symptomatic improvement in people with clinical pain. ⋯ M10/2016/095.
