Efficacy of pain treatment by modulated electromagnetic signals in Monopolar Dielectric application in women with Fibromyalgia.

INTERVENTION: 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. CONDITION: Fibromyalgia PRIMARY OUTCOME: Changes in general body pain score with Visual Analogue Scale Changes in upper trapezius pain score with Visual Analogue Scale SECONDARY OUTCOME: Changes in Anxiety and Depression measured with HADS scale Changes in quality of life impact measured with ICAF questionnaire Changes in quality of sleep measured with Visual Analogue Scale INCLUSION CRITERIA: Women diagnosed of fibromyalgia by the ACR Criteria of 1990, in treatment for the fibromyalgia syndrome symptoms (pain, depression, fatigue...)
