These results show a point prevalence of differential hypoesthesia in distal residual limbs. There was a selective loss of cold, but not warm perception or threshold for hot or cold pain by tQST. There are several possible explanations for this polymodal and selective hypoesthesia; specifically, these data may be indicative of a differential "dying back" peripheral neuropathy of the DRL, which may be operational in such clinical features as postamputation pain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
