Complex regional pain syndrome classification

Complex regional pain syndrome has been classified as type I (reflex sympathetic dystrophy with no nerve lesions) and type II (causalgia with obvious nerve damage).

The International Association for the Study of Pain has divided CRPS into two types based on the presence of nerve lesion following the injury.

• Type I, also known as reflex sympathetic dystrophy (RSD), Sudeck’s atrophy, Reflex neurovascular dystrophy (RND) or algoneurodystrophy, does not have demonstrable nerve lesions.
• Type II, also known as causalgia, has evidence of obvious nerve damage.
