Complex regional pain syndrome: evidence for warm and cold subtypes in a large prospective clinical sample.

2016

Limited research suggests that there may be Warm complex regional pain syndrome (CRPS) and Cold CRPS subtypes, with inflammatory mechanisms contributing most strongly to the former. This study for the first time used an unbiased statistical pattern recognition technique to evaluate whether distinct Warm vs Cold CRPS subtypes can be discerned in the clinical population.

Two-step cluster analysis using automated cluster selection identified a 2-cluster solution as optimal. Resul…
