Background: fibromyalgia is a disease of unknown origin characterized by chronic muscular pain. The lack of knowledge about this disease is one of the main causes that makes complex to make a diagnosis and an appropriate treatment.
Objective: the main objective of this study was to know the efficacy of a physiotherapy treatment combined with a lacto-vegetarian dietary-nutritional intervention, on low back pain and body composition in women with fibromyalgia.
Methods: twenty-one women were randomly divided into three groups: A (core stabilization exercises + lacto-vegetarian diet), B (placebo + lacto-vegetarian diet) and C (control). The intervention lasted 4 weeks. Pain assessments (EVA scale) and body composition (bioimpedance) were performed at the beginning and at the end of the intervention.
Results: group A showed significant changes in pain reduction and body composition at the end of the intervention, increasing muscle mass and decreasing fat mass. In addition, this group significantly improved outcomes compared to groups B and C. The correlations showed a relationship between muscle mass and pain reduction referred to at the end of the study in patients in group A.
Conclusions: four-week intervention program combining core stabilization exercises plus lacto-vegetarian diet in patients with fibromyalgia who have low back pain contributes to pain reduction and improved body composition.
