DescriptionThe goal of this study is to improve the way pain is measured in rodents. A previous 2019 publication by Dr. Nathan T. Fried utilized slow-motion videography and statistical modeling to analyze hind paw withdrawal caused by painful stimuli. Upon reanalyzing the one-second slow-motion videos from his study, there was more data in the facial features of the rat, which was not characterized in his work. A 2011 study performed in Dr. Jeffrey Mogil’s lab led to the development of the Rat and Mouse Grimace Scales (RGS, MGS), which measure facial features of pain in these rodents. However, their measurement using the Grimace Scale relied on 30 minutes of video analysis. This project further applies the RGS to the one-second slow-motion videos to assess facial rat grimace in response to different painful stimuli.
