Summary

This pilot study tests whether artificial intelligence can recognize pain by analyzing facial expressions in people with fibromyalgia. Researchers will compare 61 fibromyalgia patients with 61 healthy volunteers. They will also check saliva samples for biological markers of pain. The goal is to create a more objective way to measure pain, which is currently very subjective.

Who can take part

Who is studied

The study will be carried out with adult patients aged between 18 and 65 diagnosed with fibromyalgia at the outpatient clinic of the Faculdade Ciências Médicas de Minas Gerais and Clínica Ampla de Reumatologia in Belo Horizonte. The inclusion criteria were patients with no diagnosed cognitive deficit and who were willing to take part in the study. The exclusion criteria are patients who use medication that can affect anxiety or depression or who are unable to understand the instructions. Thus, once the patients agree to participate, they will be asked to sign the Informed Consent Form (ICF), which will provide detailed information about the nature of the study, the criteria for participation, the possible risks and benefits involved.
