Abstract
BACKGROUND
complex regional pain syndrome (CRPS) leads to a debilitating chronic pain condition. The lack of cause, etiology, and treatment for CRPS has been widely explored in animal models.
OBJECTIVE
Provide a comprehensive framework of the animal models used for investigating CRPS.
ELIGIBILITY CRITERIA
Preclinical studies to induce the characteristics of CRPS, with a control group, in any language or publication date.
SOURCES OF EVIDENCE
The search was performed in the Medline (PubMed) and ScienceDirect databases.
RESULTS
93 studies are included. The main objective of the included studies was to understand the CRPS model. Rats, males and adults, exposed to ischemia/reperfusion of the paw or fracture of the tibia were the most common characteristics. Nociceptive evaluation using von Frey monofilaments was the most widely adopted in the studies.
CONCLUSIONS
For the best translational science between the animal models and individuals with CRPS, future studies should include more heterogeneous animals, and multiple assessment tools, in addition to improving the description and performance of measures that reduce the risk of bias.
