Effects of Blue-enriched White Light Therapy in Patients With Fibromyalgia

Status Enrolling by invitation

Clinical Trial Summary

Fibromyalgia is a chronic condition with an unclear etiology. The syndrome includes symptoms such as chronic musculoskeletal pain, cognitive dysfunctions, fatigue, sleep disorders, and circadian rhythm disturbances. Fibromyalgia-related pain is associated with a substantial socioeconomic burden including greater health care costs and productivity loss from work. Light therapy can improve sleep quality and sleep architecture, advance sleep phases and reduce pain sensitivity and that the effect of light therapy on mood and cognitive function have been widely supported.This randomized controlled study aims to examine the effects of light therapy on sleep quality, depressive symptoms, psychomotor vigilance performance, and overall symptom severity in patients with fibromyalgia.

Clinical Trial Description

Fibromyalgia is a central sensitivity syndrome characterized by chronic widespread pain, cognitive dysfunctions, fatigue, sleep disorders, and circadian dysregulation. Light therapy can improve sleep quality and sleep architecture, advance sleep phases and reduce pain sensitivity and that the effect of light therapy on mood and cognitive function have been widely supported, research into the effect of light therapy for patients with fibromyalgia who often suffer from sleep and mood disturbance, pain, and cognitive impairments is of both research interest and therapeutic implications. This study will use a randomized, parallel group, assessor-blind, waiting-list controlled trial design. The primary outcome is symptom severity. The secondary outcomes include: sleep quality; depressive symptoms; psychomotor vigilance and attention; and sleep phase changes. The intervention will take 8 weeks with 30 minutes exposure at awakening to blue-enriched white light. A total of 80 participants, aged 20 to 64, with a diagnosis of fibromyalgia will be enrolled and randomly assigned into one of the two parallel groups: an intervention and a waiting list group. For the intervention group, outcomes will be assessed at baseline, immediately after, and 2 months after the 8-week intervention period. For the waiting list group, outcomes will be assessed at baseline, immediately after the 8-week waiting period, and 2 months after the intervention period. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
