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.
