Change on Sleep Quality of Patients With Fibromyalgia Subjected to a Combined Protocol Based on Physical Exercise and Muscle Stretching

This study evaluates the effect to a muscle stretching program combined with physical exercise versus a physical exercise program in patients with fibromyalgia.

Although classically this pathology was characterized by having an unknown etiology, current research suggests that the disease shows several abnormalities in the central pain processing. Central sensitization is defined as changes in neuroplasticity of central nervous system as a result of persistent and intense sensory information nociceptive generated by peripheral and transmitted to the neurons in the dorsal horn of the cord through the nerves of the peripheral nervous system tissues, through a constant activity of C fibers and A-beta fibers. In recent years the theory that pain is responsible for other symptoms, is changing, and it is theorized that the quality of sleep directly influences in the symptoms. The treatment of fibromyalgia is based on trying to reduce pain and associated symptoms described above in order to improve the quality of life of these patients. Almost all revisions studying the effects of physical activity in fibromyalgia agree that it is effective in reducing the overall impact on the disease and its symptoms. Muscle strength training aim to improve the strength, endurance and muscle power. There are few conclusive studies on the benefits of stretching and flexibility exercises on the impact of fibromyalgia.

Aerobic physical exercise protocol of moderate intensity, for 12 weeks, 3 sessions per week, about 12 minutes. Physical activity chosen will be pedaling on a static bike.

Stretching program on the main muscle groups of the body, for 12 weeks, 1sessions per week, about 45 minutes.

The Pittsburgh Sleep Quality Index, where a lower score (0-21), better sleep quality. Follows a continuous metric scale.

The Epworth Sleepiness Scale, where a lower score (0-24), better sleep. Follows a continuous metric scale.

The Sleep Scale from the Medical Outcomes Study evaluates the quality of sleep with a score of (0-100), where 0 is "no problem" and 100 is "maximum problems". Follows a continuous metric scale.

The visual analog scale measures the perceived pain with a score ofh a (0-100), where a higher score means more pain. Follows a continuous metric scale.

The Fibromyalgia Impact Questionnaire follows a continuous metric scale, (0-100), where a higher score means lower quality of life.

Inclusion Criteria: Be 18 years or more. To be diagnosed with fibromyalgia according to the criteria established by the "American College of Rheumatology", either on the basis of its publication of 1990 or the current revision of 2010. Accept to volunteer and give oral consent. Before starting the intervention must be provided written informed consent. Exclusion Criteria: Do not present any pathology in which physical exercise is contraindicated. Do not suffer another serious somatic illness or severe psychological disorder. Not suffer severe dementia (MMSE <10). Do not be participating at the time of the study in any other intervention of physical or psychological.
