View original scientific description
This research study is testing whether changes in sleep timing and morning light therapy may have an impact on symptoms related to fibromyalgia.
Interventions
DEVICE
Light Therapy
Participants will self-administer the daily light therapy within a few minutes of their assigned wake up time for one hour. Researchers will provide a light log to note light on/off times, any interruptions to light therapy, and primary activity during light therapy.
BEHAVIORAL
Sleep Stabilization
All participants will be asked to follow a fixed sleep schedule.
Primary outcome measures
Change in Fibromyalgia Impact Questionnaire-Revised (FIQR) score
Time frame: baseline (Visit 3, day 8) to post-treatment (Visit 7, approximately day 36).
The FIQR is 21 questions. Each question has 11 boxes similar to a visual analog scale. Questions include the difficulty associated with various physical activities and the severity of symptoms. The score for the questions is on a scale from 0 - 100, where lower scores represented better functional status.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
