The University of Regina (U of R) in Canada says its researchers have developed a system that can recognize when non-verbal adults with dementia are in pain, along with a notification system.
U of R's Thomas Hadjistavropoulos and his team have devised methods to detect, evaluate, and measure pain in adults with dementia via specific facial responses that are relatively uncommon in non-painful situations.
When the system's strategically placed cameras detect patients in pain, nursing staff will receive an email while a light at the nursing station would flash to signal the email's transmission.
The researchers are modifying an algorithm for spotting pain behaviors in older people by distinguishing between wrinkles and frowns. "We're doing it so that it works under less-than-ideal lighting and camera conditions to make it affordable," Hadjistavropoulos notes.
