Outcome Measures

Primary Outcomes (1)

  • Change in Fibromyalgia Impact Questionnaire-Revised (FIQR) score

    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.

    baseline (Visit 3, day 8) to post-treatment (Visit 7, approximately day 36).

Secondary Outcomes (1)

  • Change in Brief Pain Inventory (BPI) score

    baseline (Visit 3, day 8) to post-treatment (Visit 7, approximately day 36).

Study Arms (3)

Light Therapy

EXPERIMENTAL

All participants will be asked to attend 8 virtual visits over 5 months. Participants randomized to the morning light therapy group are asked to wear the glasses for 1 hour per day. The timing of each person's therapy is tailored to their average wake up time during a baseline period. The treatment period is 4 weeks long.

Device: Light Therapy

Sleep Stabilization

EXPERIMENTAL

All participants will be asked to attend 8 virtual visits over 5 months. Participants randomized to the sleep stabilization arm are asked to follow a fixed sleep schedule tailored to their sleep during a baseline period. The treatment period is 4 weeks.

Behavioral: Sleep Stabilization

Control Group, treatment as usual

NO INTERVENTION

Participants will be asked to sleep as per usual.

Interventions

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.

Also known as: Re-Timer
Light Therapy

All participants will be asked to follow a fixed sleep schedule.
