Impact of a Specific Training Program on the Neuromodulation of Pain in Fibromyalgia Subjects

A specific training program under the guidance of a physiotherapist, a professor of Adapted Physical Activity (APA) and individualized whose objective is to strengthen the parasympathetic tone and modulate the reactivity of the sympathetic system and the report of the Hypothalamic-Pituitary-Adrenal (HPA) axis.This training program consists of three sessions of 45 minutes of physical activity per week for 2 years. The exercise intensity is initially very low and will be gradually increased according to your abilities and your tolerance to stress. A 6-Minute Walk Test (6MWT) will be carried out by the physiotherapist and by Professor APA, every 6 months to monitor the progression. For tracking the training program, a phone call is scheduled every week during the first 3 months, then a phone call every 15 days during the following months until the end of the study.Evaluation of neuromodulation of pain will be measured thanks to thermodeTest , experimental method implementing a tonic thermal pain using a "Peltier type Thermode" 3 cm2 model TSA II and immersion in a bath of cold water.

Participants will be randomly assigned to 2 groups, "Training" group or "Control" group.

The control group is a training program supervised by physical therapists and teachers in Adapted Physical Activity, identical to the active program in its follow-up, but the intensity of the sessions is lower.

Study schedule :

• 1st visit : screening visit at D-30
• 2nd visit : inclusion at D-7
• 3rd visit at D0
• 4st visit between M6 and M9
• 5th visit at M24

The patients included in the study will receive in addition to the training program, taking into bio-psycho-social multidisciplinary.
