Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment Sleep Stabilization + Light Therapy for Fibromyalgia?

Light therapy has been shown to be effective in treating mood and sleep disturbances in various conditions, such as Seasonal Affective Disorder and insomnia, by improving sleep quality and mood. Additionally, morning light exposure has been found to enhance sleep quality and reduce daytime sleepiness in individuals with sleep disruptions. ^{1 2 3 4 5}

Is Sleep Stabilization and Light Therapy safe for humans?

The research does not provide specific safety data for Sleep Stabilization and Light Therapy in humans, but these treatments are generally considered safe when used appropriately. Bright light therapy, often used for conditions like seasonal affective disorder, is typically well-tolerated, though it can cause mild side effects like eye strain or headaches. ^{6 7 8 9 10}

How does the Sleep Stabilization + Light Therapy treatment for fibromyalgia differ from other treatments?

This treatment is unique because it combines sleep stabilization with light therapy, which uses exposure to specific light intensities to help regulate sleep patterns. Unlike traditional medications, this approach focuses on adjusting the body's internal clock and improving sleep quality, which may help alleviate fibromyalgia symptoms. ^{3 5 11 12 13}

What is the purpose of this trial?

This research study is testing whether changes in sleep timing and morning light therapy may have an impact on symptoms related to fibromyalgia.

Findings from Research

Light therapy is an effective, evidence-based treatment for Seasonal Affective Disorder, influencing circadian rhythms that affect sleep, mood, and cognition, based on 40 years of clinical trials.

For optimal results, light therapy should use devices that provide 10,000 lux of white light for 30-60 minutes in the early morning, with ongoing monitoring to adjust treatment as needed and manage any side effects.

Bright light therapy has been shown to significantly improve wake after sleep onset (WASO) in individuals with insomnia, based on a meta-analysis of 22 studies involving 685 participants.

While light therapy did not affect other sleep measures like sleep latency or total sleep time, it demonstrated potential for personalized treatment approaches by adjusting light exposure based on the type of insomnia.

A review of five randomized controlled trials found that light therapy generally had no significant impact on sleep macro-architecture measures like total sleep time and sleep efficiency in patients with insomnia, except for one trial that showed improved sleep efficiency with evening light therapy.

In patients with delayed sleep-wake phase disorder (DSWPD), bright light therapy significantly increased sleep latency in the morning, indicating that timing and intensity of light exposure can influence sleep patterns, but overall research on light therapy's effects on EEG sleep measures is still limited.

In a study of 35 adults aged 18 to 45 with mild traumatic brain injury, daily 30-minute sessions of blue light therapy for 6 weeks significantly improved sleep quality and reduced daytime sleepiness compared to placebo amber light therapy.

Participants receiving blue light therapy also reported lower levels of depression and post-concussion symptoms, suggesting that this nonpharmacological treatment could effectively address multiple issues related to sleep disruption after a mild traumatic brain injury.

Light therapy is being used more frequently to treat various sleep and psychiatric conditions, such as circadian rhythm sleep disorders and seasonal affective disorder, highlighting its growing importance in clinical practice.

Understanding the neural mechanisms behind circadian rhythms is essential for leveraging light therapy effectively, as it can significantly influence brain function and improve mood and sleep disorders.

In a trial involving 64 women with fibromyalgia and insomnia, cognitive-behavioral therapy for insomnia (CBT-I) led to significant improvements in sleep quality, fatigue, daily functioning, pain catastrophizing, anxiety, and depression compared to a sleep hygiene education program.

The CBT-I group showed greater overall improvements in various clinical symptoms than the sleep hygiene group, highlighting its effectiveness as part of a comprehensive treatment plan for fibromyalgia.

In a study of 100 drug-free fibromyalgia patients, those with an evening chronotype experienced more severe symptoms and poorer quality of life compared to morning or neither types, highlighting the importance of chronotype in managing fibromyalgia.

The evening chronotype accounted for an additional 21.9% of the variation in fibromyalgia severity, suggesting that considering a patient's chronotype could improve treatment responses and overall management of the condition.

The Fibromyalgia Sleep Diary (FMSD) was developed as a patient-reported outcome measure specifically for assessing sleep disturbances in fibromyalgia patients, based on extensive qualitative research including literature reviews, expert interviews, and focus groups with patients.

Preliminary cognitive interviews indicated that the FMSD is relevant and accurately reflects the sleep issues experienced by fibromyalgia patients, such as poor sleep quality and difficulty staying asleep, supporting its content validity for future psychometric evaluation.

The study evaluated the reliability of the Medical Outcomes Study Sleep Scale (MOS-SS) in patients with fibromyalgia, finding that both a 1-week and a 4-week recall period provided similar and high reliability for measuring sleep disturbances.

With 129 patients participating, the results indicated that the 1-week recall period is sufficiently reliable for assessing sleep issues in fibromyalgia, making it a practical option for future studies.

A study involving 10 women with fibromyalgia found that both morning and evening bright light treatments improved function and pain sensitivity, but morning light treatment resulted in a clinically meaningful improvement in function, with over a 14% reduction in Fibromyalgia Impact Questionnaire scores.

Morning light treatment also significantly increased pain threshold compared to evening light, suggesting that advancing circadian timing may be a key mechanism for improving pain sensitivity in fibromyalgia patients.

A study involving 33 Veterans with mild traumatic brain injury (TBI) found that morning bright light therapy was feasible and well-accepted, with about 75% of participants rating the protocol favorably and high adherence rates (87% for lightbox use and 97% for sleep tracking).

Post-treatment, participants reported significant improvements in insomnia, mood, and pain, along with better sleep measured by actigraphy and favorable changes in blood biomarkers, suggesting that bright light therapy could be an effective intervention for sleep disturbances in TBI patients.

In two case studies involving individuals with traumatic brain injury (TBI), an 8-week personalized in-home light therapy significantly reduced fatigue, sleep disturbance, and insomnia symptoms, demonstrating its potential efficacy as a treatment.

Participants reported high compliance (over 70%) and found the light therapy feasible and well-tolerated, with no serious side effects, indicating it could be a safe and acceptable intervention for improving quality of life after brain injury.

Light therapy is generally safe and effective for treating delayed sleep phase syndrome (DSPS) and advanced sleep phase syndrome (ASPS), according to clinical guidelines developed by the American Academy of Sleep Medicine.

While light therapy shows potential benefits for conditions like jet lag, shift work, and non-24-hour sleep-wake syndrome, its efficacy in these areas is less clear, particularly for some blind patients.
