Detaljeret beskrivelse

Fibromyalgia is one of the rheumatic diseases with the greatest impact on the quality of life, whose etiology and pathophysiology is not yet fully demonstrated. Perhaps this is why its therapeutic approach is refractory to current treatments.

Based on the theory that fibromyalgia is characterized by a sensitization at the level of the central nervous system that leads to an increase in the perception of pain, any therapeutic approach aimed at modulating the central nervous system may be beneficial. Electrical stimulation with transcranial direct current (tDCS) is among these techniques.

In the same way, therapeutic exercise has shown to have, like the tDCS, a beneficial effect on pain in different chronic pathologies.

The present study aims to investigate the effect on pain of a combination therapy of tDCS and therapeutic exercise in patients with fibromyalgia.

Eksperimentel: Real tDCS + exercise
Transcranial direct current stimulation combined with therapeutic exercise
Enhed: Real tDCS
Real tDCS (STARTSTIM® 8 stimulator, Neuroelectric Barcelona, Spain) for five sessions on alternate days.tDCS is a galvanic current applied by a cap for 20 minutes at an intensity of 2 milliamps.
Enhed: Therapeutic exercise
The therapeutic exercise program will include aerobic exercise and muscle strengthening for five sessions on alternate days. The program will include exercises and will last 30-45 minutes.
Sham-komparator: Sham tDCS + exercise
Sham transcranial direct current stimulation combined with therapeutic exercise
Enhed: Therapeutic exercise
The therapeutic exercise program will include aerobic exercise and muscle strengthening for five sessions on alternate days. The program will include exercises and will last 30-45 minutes.
Enhed: Sham tDCS
Sham current (STARSTIM® 8 stimulator, Neuroelectric Barcelona, Spain) for five sessions on alternate days. Sham tDCS will be applied for the same time than real tDCS.

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Change in referred pain area after suprathreshold pressure stimulation from baseline to post-treatment
Tidsramme: Baseline; immediately after intervention; 1-month after intervention

A pressure algometer (Force Ten™, Wagner Instruments, USA) will be used. It will be performed on the infraspinatus muscle (point equidistant between the midpoint of the spine of the scapula, the inferior angle of the scapula and the midpoint of the medial border of the scapula) at a constant suprathreshold pressure (20% above the pressure pain threshold) for 60 seconds.

After the stimulation, the subject should draw the induced pain area on a digital bodychart using the Navigate Pain application (Navigate Pain, Aalborg University, Denmark).
Baseline; immediately after intervention; 1-month after intervention
Change in pain intensity from baseline to post-treatment
Tidsramme: Baseline; immediately after intervention; 1-month after intervention
It will be measured with a visual analog scale (VAS) of 100 millimeters in length. The subject has to indicate the level of pain he feels, being 0 the absence of pain and 100 the maximum imaginable
Baseline; immediately after intervention; 1-month after intervention

Tidsramme
Fibromyalgi påvirker livskvaliteten
Tidsramme: Baseline; umiddelbart efter intervention; 1 måned efter indgreb
Det vil blive målt med den version, der er tilpasset den spanske af Fibromyalgi Impact Questionnaire (FIQ). Skalaen går fra 0 til 100. Højere værdier repræsenterer et dårligere resultat.
Baseline; umiddelbart efter intervention; 1 måned efter indgreb
Anxiety
Tidsramme: Baseline; immediately after intervention; 1-month after intervention
The version adapted to Spanish from the State Scale (STAI-ES) of the State-Trait Anxiety Inventory (STAI) will be used. The scale ranges from 0 to 60. Higher values represent a worse result.
Baseline; immediately after intervention; 1-month after intervention
Pain catastrophizing
Tidsramme: Baseline; immediately after intervention; 1-month after intervention
The Spanish version of the Pain Catastrophizing Scale (PCS) will be used. The scale ranges from 0 to 52. Higher values represent a worse result.
Baseline; immediately after intervention; 1-month after intervention
Depression
Tidsramme: Baseline; immediately after intervention; 1-month after intervention
The adaptation to the Spanish of Beck Depression Inventory II will be used. The scale ranges from 0 to 63. Higher values represent a worse result.
