Record History

  1. Study First Submitted
  • Stopped: an ongoing trial was terminated, suspended or withdrawn.

  • Minor: routine progress and housekeeping, such as sites added or enrollment closed.
This pilot randomized, double-blind, crossover clinical trial will evaluate the feasibility and preliminary efficacy of chromatic (colored) light exposure for reducing pain severity and pain sensitivity in adults with fibromyalgia or chronic widespread pain and fatigue. Participants will complete daily symptom surveys throughout the study and undergo patient-reported outcome assessments and quantitative sensory testing at multiple timepoints. Participants will be randomized to receive either S-cone stimulating chromatic light or equal-energy white light for 2 hours daily over a 7-day treatment period. Following a 1-week washout, participants will cross over to the alternate condition. Outcomes will examine feasibility, changes in pain severity, pain interference, and measures of pain sensitivity. Total study duration is approximately 35 days.
