During a PainChek® assessment, a camera-enabled smartphone or tablet is used to perform a real-time, AI driven analysis of the person’s face, recording micro expressions proven to be indicative of pain. The assessor’s clinical observations on pain related behaviours such as movement and voice are then recorded through an intelligently automated framework, standardising the observation format. This data is used to generate an overall pain rating – the key clinical output of the PainChek® assessment.

Where the NRS assessment is used, the PainChek® app guides the assessor to ask a standardised question, quantifying the level of pain being experienced, and if relevant, the location of pain.
