Effects of Diatermy in Patients With Fibromyalgia.

A DT equipment (CET 400 VA - RET 130 Watts - Winback, France), with a frequency of 500 kHz and intensity at 40% will be used. It will be applied utilizing a flat capacitive head 4 cm in diameter. It will be applied using longitudinal and transverse movements and a conductive cream for DT. DT will be used over the TP of the right and left trochanteric prominence. The settings will be calibrated so that patients fell no more than mild warmth during the treatment.

This same intervention that has been given to the experimental group, will be simulated as placebo in the control group; the DT will not be activated during administration.
