Effects of Nutritional Strategies or Manual Therapies in Women With Fibromyalgia


The study had two objectives. The first main aim was to analyze the effects of tryptophan and magnesium-enriched Mediterranean diet on psychological variables (trait anxiety, self-image, mood state, eating disorders) and sleep effects in women with fibromyalgia. Our hypothesis, based on previous positive effects of tryptophan and magnesium supplementation by separate in this population, may improve psychological health and regulate sleep disruptions. The second aim was to assess the effectiveness of a manual therapy technique performed with moderate digital pressure in fibromyalgia patients on the variables of fatigue, pain, sleep, anxiety and mood. It was done to provide an alternative treatment to pharmacological therapies for fibromyalgia patients and to provide new evidence on the effects of manual therapy in fibromyalgia patients.
