What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Light therapy A (Bright) via the Re-Timer®Device

    Also called Re-Timer®

    Subjects will conduct light treatment in the mornings at home for one hour using Re-timer®.

  • Light therapy B (Dim) via the Re-Timer®Device

    Also called Re-Timer®

    Subjects will conduct light treatment in the mornings at home for one hour using Re-timer®.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fibromyalgia Impact Questionnaire, Revised (FIQ-R) Score

    The FIQR consisted of 21 questions. Each question had 11 boxes similar to a visual analog scale. Questions covered the difficulty associated with various physical activities and the severity of symptoms. The score for the questions was on a scale from 0 - 100, where lower scores represented better functional status.

    Measured: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline)

Secondary outcomes (3)
  1. Heat Pain Threshold Assessed by the Heat Pain Sensitivity Test

    Pain threshold was assessed during a heat pain sensitivity task using a Medoc TSAII NeuroSensory Analyzer and an ascending method of limits protocol. The threshold was the temperature (in degrees Celsius) at which the participant reported the stimulus felt painful.

    Measured: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline)

  2. Heat Pain Tolerance Assessed by the Heat Pain Sensitivity Test

    Pain tolerance was assessed during a heat pain sensitivity task using a Medoc TSAII NeuroSensory Analyzer and an ascending method of limits protocol. The tolerance was the temperature (in degrees Celsius) at which the participant reported the stimulus was so painful that they had to stop.

    Measured: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline).

  3. Patient Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Score

    Pain was assessed with the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity 3a short form, which assesses worst and average pain in the past 7 days (1=no pain to 5=very severe) and current level of pain (1=no pain to 5= very severe). Scores were summed and converted to a T score metric (mean ±SD, 50 ±10); higher scores indicate more pain.

    Measured: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline).

Questions about this trial

What is this clinical trial studying?

A study testing Light therapy A (Bright) via the Re-Timer® and Light therapy B (Dim) via the Re-Timer® in people with Fibromyalgia and FMS, run by University of Michigan at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Oct 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fibromyalgia Impact Questionnaire, Revised (FIQ-R) Score (time frame: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Oct 2022.
