[HTML][HTML] Facial expressions of horses using weighted multivariate statistics for assessment of subtle local pain induced by polylactide-based polymers implanted …
Simple Summary Facial expression (FE) has been used for pain diagnosis in horses. The
current study aimed to identify pain in horses undergoing under-skin polylactide-based
polymer implantation. Five statistical methods for analyzing FE were used, including
conventional and new approaches. First, we scored the seven FEs separately.
Subsequently, the scores of the seven FEs were added (SUM). Subsequently, principal
component analysis (PCoA) was performed using the scores of the seven FEs obtained …

Facial-expression-based analysis has been widely applied as a pain coding system in
horses. Herein, we aimed to identify pain in horses undergoing subcutaneously polylactide-
based polymer implantation. The sham group was submitted only to surgical incision. The
horses were filmed before and 24 and 48 h after implantation. Five statistical methods for
evaluating their facial expressions (FEs) were tested. Primarily, three levels of scores (0, 1,
and 2) were applied to the seven
