Study Summary

This trial will help us to understand how GLED works to decrease pain, which will provide support for using light therapy as a treatment for pain.

Who is the study for?
This trial is for adults over 18 who speak English, have been diagnosed with fibromyalgia according to specific criteria, and experience chronic pain rated at least 5 out of 10 despite medical treatment. People with serious mental illness, color blindness, uncorrected cataracts or those paid for their condition are excluded.Check my eligibility
What is being tested?
The study tests Green Light Therapy (GLED) as a potential treatment for fibromyalgia and chronic pain. It aims to understand how GLED might reduce pain by affecting the brain's processing of pain signals. Participants will be randomly assigned to receive either GLED or a placebo in a controlled environment.See study design
What are the potential side effects?
Previous studies suggest that Green Light Therapy does not cause adverse effects and does not impair motor performance. However, individual experiences may vary during the course of this research.
