Brief Summary

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

The main objective is to know if the transcranial static magnetic field stimulation (tSMS) reduces the perception of pain in patients with fibromyalgia and its effect on health-related quality of life. In addition, it will seek to limit the parameters necessary to achieve efficiency with the technique.

Detailed Description

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

Background:

Various non-invasive brain stimulation techniques have been successfully tested in fibromyalgia syndrome (FMS). Transcranial static magnetic field stimulation (tSMS) is a new, portable and inexpensive non invasive brain stimulation (NIBS) technique that has shown security, biological effects, and therapeutical effects in some pathologies. Some studies have studied its effect in pain central processing, our aim is to study its effect on FMS. The safety that tSMS has demonstrated in several clinical trials opens doors to future clinical trials that will extend its clinical utility.

Objectives:

To investigate the effect of tSMS on pain in patients with FMS, using subjective and objective assessment measures. Identify dose response to the treatment to limit the parameters required to achieve effectiveness with the technique.
