Study type | Interventional |
Fibromyalgia affects an average of 2% of the French population. Data from the literature report that low levels of magnesium could be associated with fibromyalgia. However, no study to date has investigated the effect of oral magnesium administration on stress in fibromyalgia. This trial therefore aims to evaluate whether magnesium could improve stress and the various disorders that contribute to the complexity of fibromyalgia, including pain, cognition, sleep disorders and quality of life.

Primary | Measure of stress with DASS-42 | Measure of stress with stress subscale in magnesium and placebo group. This subscale consists of 14 questions of self-evaluation | at day 0 | |
Secondary | Evaluation of the impact of fibromyalgia using the FIQ questionnaire | The revised FIQ questionnaire is a 10-item self-questionnaire that assesses the impact of fibromyalgia | Day0; Day0+28; Day0+84 | |
Secondary | Detection of fibromyalgia using the FIRST questionnaire | The FIRST questionnaire is a 6-item self-questionnaire that detects fibromyalgia. | Day0; Day0+28; Day0+84 | |
Secondary | Evaluation of stress by the heart rate variability | Heart rate variability (HRV / HRV) is a measure of changes in heart rate that will provide an estimate of stress. It is usually calculated by analyzing time series of beat-by-beat intervals of the ECG or blood pressure plots. | Day0-7; Day0; Day0+28; Day0+84 | |
Secondary | Assessment Using Numerical Scale (EN) | This scale allows the patient to note the pain on a graduation whose minimum score is 0 and the maximum score is 10. | Day0; Day0+28; Day0+84 | |
Secondary | Concise Pain Questionnaire (QCD) | This self-assessment scale allows the patient to characterize the pain in relation to its psychosocial intensity and impact. The patient is asked to answer 9 graduated questions by circling a number from 0 (no pain) to 10 (the most horrible pain you can imagine). | Day0; Day0+28; Day0+84 | |
Secondary | Evaluation of the impact on cognition by the Trail Making Test A and B (TMT A and B) and the Cantab® test | The Trail Making Test (TMT) is recognized as one of the most frequently used neuropsychological tests in clinical practice alternating numbers and letters (1-A-2-B-3- C, etc.). The Cantab® is a comprehension test, executive functions, memory, attention and decision-making. |

Secondary | Evaluation of the emotions by visualization of images and scale evaluating the feelings of the patients | The International Affective Picture System (IAPS) is a library of 1200 standardized images that can induce an emotional reaction, constituting as many emotional stimuli (positive or negative) or not (neutral). | Day0; Day0+28; Day0+84 | |
Secondary | Evaluation of the overall impression of change by the Patient Global Impression of Change Questionnaire (PGIC) | The Global Impression of Change Patient is a scale of global perception of change ("deterioration" or "improvement") completed by the patient. This scale is graduated from 1 = much better to 7 = significantly worse | Day0; Day0+28; Day0+84 | |
Secondary | Evaluation of the impact on the Pittsburg Sleep Quality Index (PSQI) | The Pittsburg Sleep Quality Index is a self-administered questionnaire with 19 items. It has been developed to measure the quality of sleep in the month preceding the interview with the patient. This questionnaire has 7 components: subjective sleep quality, sleep latency, sleep duration, usual sleep efficiency, sleep disorders, use of a sleep medication, and poor daytime fitness | Day0; Day0+28; Day0+84 | |
Secondary | Evaluation of the intensity of fatigue by the Fatigue Severity Scale (FSS) | The fatigue severity scale is a 9-item self-questionnaire to assess the patient's fatigue intensity. The patient is asked to circle a number from 1 to 7 for each question, a low value representing a low intensity | Day0; Day0+28; Day0+84 | |
Secondary | Social Vulnerability Assessment (EPICES) | The EPICES questionnaire is composed of 11 binary questions (yes / no) allowing to calculate an individual score indicating the precariousness and inequalities of health ranging from 0 to 100. | Day0; Day0+28; Day0+84 | |
Secondary | Evaluation of catastrophism by the PCS (Pain Catastrophizing Scale) scale | Pain Catastrophizing Scale (PCS) is a questionnaire in which the patient is asked to describe the kind of thought and emotions they feel during pain. This questionnaire consists of 13 items describing different thoughts or emotions that may be associated with the pain. The patient will have to indicate how much he has these thoughts or emotions when he feels pain by giving a score between 0 and 4, 0: not at all, 4: all the time. The final score is the sum of the scores for each question. | Day0; Day0+28; Day0+84 | |

Secondary | Evaluation of genetic polymorphism using OpenArray technology | Identification of genes involved | Day0-7 | |
Secondary | Evaluation of stress response during visual stimulation | Stress intensity will be assessed by the numerical stress rating scale: the scale ranges from 0 "no stress" to 10 "maximal stress" following different visual stimulation induced by different colors during the anticipatory phase of pain. | Day0; Day0+28 | |
Secondary | Evaluation of pain response during thermal stimulation | Pain intensity will be assessed by the numerical pain rating scale (NPRS): the scale ranges from 0 "no pain" to 10 "maximal tolerable pain" following different thermal stimulations (using Pathway Medoc®). | Day0; Day0+28 | |
