Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There will be two study arms: Intervention and control.

-Intervention group will receive eight treatment sessions of 20 minutes of duration along two weeks (from Monday to Friday the first week and Monday, Wednesday and Friday the second week). In each of them, a Dielectric Monopolar Electromagnetic Signals Device will be used to treat the patient upper trapezius by massaging and heating (38 degrees Celsius) it with the device applicator, which will use a 30 volts and 800-900 kilohertz range emission. The pressure used will be of 2kg in order to reach pressure enough without producing pain. The treatment will be held on a wood portable physiotherapy table, situated in a climatized room. The patients will be on the table in prone position all along the treatment. A physiotherapist with over 5 years of experience will deliver the treatment.

In order to maintain adherence to the treatment, the physiotherapist who treat the intervention group will remember the patients to come to treatment by phoning them the day before.

Statistical methods / analysis
The sample size was calculated by the software ENE 3.0, using as reference data from the study of Sutbeyaz ST et al. (2009) to find differences between two samples with 1% of signification and 90% statistical power , resulting a total of 26 patients. Taking into account expected losses of 12.5% (Sutbeyaz ST, 2009), a minimum of 30 patients should be included, so it will eventually include about 50 to ensure representativeness.

To carry the statistical analysis of the data, MedCalc software version 16.4.3 for Windows will be used, considering a statically significant a 0,05 value. A homogeneity analysis will be done by Shapiro-Wilk test, noting the values as media and standard deviation.

General and upper trapezius pain variables will be analyzed with ANOVA of repeated measures to detect changes in pain along the treatment, using as intra subject factor the time and as inter subject factor the treatment received by the patient. After that, Cohen's d will be calculated to measured the effect size of each treatment before and after the intervention.

In quality of life impact, depression, anxiety and quality of sleep variables, an ANOVA test will be carried considering treatment group as factor. To check the possible differences between before and after the intervention on each arm, a T test will be calculated. Cohen's d will be calculated to measure the effect size of the treatment on each variable.

A Spearman correlation analysis will be done to check the possible relations among the variables.

Summary
Brief summary
Fibromyalgia is one of the most important health problem in developed countries with a prevalence of 2,1% and health costs growing every year. Patients with fibromyalgia suffer pain all over the body and many other symptoms such as depression, headache, irritable colon, painful menstruation, irritability, thermal sensitivity, fatigue, joint stiffness and sleep disturbances. At the moment, fibromyalgia lacks of an effective treatment, among others things because there is no consensus about its etiology. Its approach consist on symptomatic treatment of pain and the associated symptoms by medication. The poor results of medication at relief pain at long time and the adverse effects as risk of dependence and tolerance of some drugs make necessary to find alternative safer and good quality treatments.

Dielectric Monopolar Electromagnetic Signals treatment has been successfully tried to treat neuropathic pain and some types of chronic pain, presenting no adverse effects and with a reduce cost of maintenance, reasons that show it has an interesting alternative for fibromyalgia treatment.

Hypothesis
-Dielectric Monopolar Electromagnetic Signals (DMES) treatment will improve at short time the upper trapezius and the general pain of fibromyalgia patients.
-DMES treatment will improve at short time the quality of life impact, the depression, the anxiety and the quality of sleep in fibromyalgia patients.
-Standard treatment added to DMES treatment will be more effective than only the standard treatment of the patients.

Objectives:
-To check the efficacy at short time of DMES treatment in releasing upper trapezius and general pain in fibromyalgia patients.
-To check the influence of DMES treatment on quality of life impact, depression, anxiety and quality of sleep in fibromyalgia patients.
-To measured if DMES treatment added to the standard treatment of patients get bigger improvement in subjects variables than only the standard treatment of patients.
