Facial recognition software to detect neonatal pain

To study whether computerized recognition of facial expressions can accurately detect neonatal pain, researchers from Brazil obtained nearly 6000 facial images from 30 neonates in the resting state and when undergoing painful procedures. These images were then analyzed by computer software, and 12 randomly selected images per infant were also analyzed by experienced health professionals. The computer software had a sensitivity of 100% and specificity of 100% in detecting pain using the health professional evaluation as the reference standard.
