Can a new scale give voice to pain in the blind?
NCT ID NCT03968991
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This study tests whether a new tool, the VISIODOL® scale, can help people with visual impairment communicate pain. Researchers will compare pain ratings from this scale with those from a standard numerical scale during heat-induced pain. The study includes healthy volunteers with and without visual impairment, aiming to see if the scale is a reliable way to assess pain in this population.
