Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the effects on fatigue and sleep of Unihemispheric Concurrent Dual-Site anodal Transcranial Direct Current Stimulation combined with therapeutic exercise in Fibromyalgia patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Fibromyalgia (FM) 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.

Apart from the widespread chronic pain characteristic of this syndrome, fatigue is a very disabling symptom in this pathology. It is a complicated, multifactorial, disconcerting and very persistent symptom that is highly frequent in FM. A vast majority of the published studies have focused the symptoms studied in FM on pain, while fatigue and sleep disturbances, despite not being minor symptoms, have not received the same attention.

Neuromodulation treatments with transcranial direct current stimulation (tDCS) have been shown to induce significant analgesia in FM through modification of sensory processing of pain by thalamic inhibitory circuits and improvement of sleep architecture. On the other hand, therapeutic exercise (TE) programs based on aerobic work and global muscle strengthening have been shown to have a beneficial effect in reducing the pain and severity of FM.

None of the four studies conducted so far combining tDCS and TE in fibromyalgia have evaluated the effect on fatigue or sleep. Currently, various studies conclude that Unihemispheric Concurrent Dual-Site anodal Transcranial Direct Current Stimulation (UHCDS a-tDCS) on the dorsolateral prefrontal cortex (DLPFC) and M1 produces a 50% greater modulation of corticospinal excitability. To date, no RCT has studied its effect in subjects with FM.

The present study aims to investigate the effect of UHCDS a-tDCS combined with TE on fatigue and sleep quality in subjects with FM.

Real UHCDS a-TDCS + Therapeutic Exercise

Real unihemispheric concurrent dual-site anodal transcranial direct current stimulation combined with therapeutic exercise

Group Type EXPERIMENTAL

Real UHCDS a-tDCS

Intervention Type DEVICE

Real UHCDS a-tDCS (STARTSTIM® 8 stimulator, Neuroelectric Barcelona, Spain) for ten sessions (three sessions per week in weeks 1 and 2; and one session per week in weeks 3, 4, 5 and 6). UHCDS a-tDCS is a galvanic current applied by a cap for 20 minutes at an intensity of 2 milliamps.

Therapeutic exercise

Intervention Type DEVICE

The therapeutic exercise program will include aerobic exercise and muscle strengthening in the same days as UHCDS a-tDCS. The program will last 30-45 minutes.

Sham UHCDS a-TDCS + Therapeutic Exercise

Sham unihemispheric concurrent dual-site anodal transcranial direct current stimulation combined with therapeutic exercise

Group Type SHAM_COMPARATOR

Therapeutic exercise

Intervention Type DEVICE

The therapeutic exercise program will include aerobic exercise and muscle strengthening in the same days as UHCDS a-tDCS. The program will last 30-45 minutes.

Sham UHCDS a-tDCS

Intervention Type DEVICE

Sham UHCDS a-tDCS (STARSTIM® 8 stimulator, Neuroelectric Barcelona, Spain) for ten sessions (three sessions per week in weeks 1 and 2; and one session per week in weeks 3, 4, 5 and 6). Sham tDCS will be applied for the same time than real UHCDS a-tDCS.
