Pain is one of the most personal experiences we have, and one of the hardest to explain. However, technology is now coming into play to prove it. A new AI-powered app called PainChek®is helping doctors and caregivers assess pain, even in people who cannot communicate how they feel. But can a smartphone really capture something so subjective?
Pain is notoriously tricky to quantify. Think about it: if someone asks you to rate your pain on a scale from 1 to 10, how do you choose a number? Past injuries, mood, and expectations all influence the answer. What feels like a 6 to one person might be an 8 to someone else. The complexity is part of what makes pain so challenging for medical professionals, and why tools like PainChek® are so intriguing [1].
How PainChek® Works?
The app uses AI to analyse small facial expressions, such as brow pinches or lip movements, and combines this with a checklist to detect other signs of pain. It creates personalized pain profiles, helping caregivers understand everyone’s unique experience.
While it’s especially useful for people who cannot self-report, like those with dementia, PainChek® also offers valuable insights for anyone receiving care. By providing consistent and objective data, it supports better clinical decision-making, faster intervention, and improved quality of life.
Even with these advances, artificial intelligence cannot replace the human experience. Pain is subjective, and self-report remains the gold standard. But tools like PainChek® show how technology can complement human judgment, giving caregivers the information they need to respond quickly and compassionately [2].
With over 15.9 million assessments completed worldwide, PainChek® is already helping care facilities provide safer, more effective pain management, and showing that even the most personal human experiences can benefit from a little digital help.
