Summary

This study tests whether a special band-aid (called the A-Band) and a smartwatch can measure pain in women with chronic pain using AI. About 115 women with chronic pain and healthy women will wear the devices for a week and report their pain levels. The goal is to see if the devices can accurately match what people say about their pain. No treatment is given—this is only about measuring pain better.
