Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Fibromyalgia Impact Questionnaire, Revised (FIQ-R) Score
Time Frame: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline)
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.
Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Heat Pain Threshold Assessed by the Heat Pain Sensitivity Test
Time Frame: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline)
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.
Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline)
Heat Pain Tolerance Assessed by the Heat Pain Sensitivity Test
Time Frame: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline).
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.
Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline).
Patient Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Score
Time Frame: Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline).
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.
Baseline (1 week), Mid-Treatment (2 weeks post-baseline), Post-Treatment (4 weeks post-baseline).
