About

Some fibromyalgia patients may use inappropriate emotional regulation strategies to respond to pain. Rumination could be one of this inefficient regulation strategies. The investigators believe that the use of rumination strategies to respond to the discomfort of daily physical activity would maintain and aggravate a negative emotional state after the effort. Distraction would be a more effective strategy to cope with pain. From this data, the investigators want to explore the causal link between rumination and negative affectivity after physical activity in fibromyalgia using an experimental design.

Full description

Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory and mood issues. As with any condition of chronic pain, psychological mechanisms can help maintain discomfort and pain. These mechanisms may hinder the recovery of physical activity. Some patients may use cognitive strategies of emotional regulation that are ineffective to cope with pain and discomfort of everyday activities, such as rumination. The literature suggests that this process is linked to the physical and psychological difficulties of fibromyalgia. However, no study has revealed a causal link between rumination and negative affectivity in a context of physical activity in this population. The investigators want to test this hypothesis by directly manipulating the style of information processing following a relevant activity for these patients: climbing steps. In one group the investigators will induce rumination right after climbing the steps. In the other group the investigators will induce distraction. Patient with Fibromyalgia will be recruited at the Pain Center of CHU-Amiens. Patients will complete different scales before to climb steps and after experimental induction. The investigators hypothesize that Patients using a rumination strategy after an uncomfortable physical activity will experience a greater subjective discomfort than patients using a distraction strategy.
