About this study
Official title: Effect of Transcranial Static Magnetic Field Stimulation Over the Primary Motor Cortex in Fibromyalgia Syndrome: A Randomized Controlled Pilot Study
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.
Read the detailed description
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from Self-reported pain intensity
Self-reported pain intensity evaluated by the Visual Analogue Scale (VAS).
Measured: At the start of the study (at baseline, 0 week), after the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week) and 3 months from the last session (16th week)
Change from Self-reported quality of life
Self-reported quality of life evaluated by the Fibromyalgia Impact Questionnaire (FIQ).
Measured: At the start of the study (at baseline, 0 week), after the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week)) and 3 months from the last session (16th week)
Secondary outcomes (7)
Change from Self-reported catastrophizing
Self-reported catastrophizing evaluated by the Pain Catastrophizing Scale: 13 items, using the 0 (not at all) to 4 (all the time) scale. A total score is yielded (ranging from 0-52), the worse the result the higher the score.
Measured: At the start of the study (at baseline, 0 week), after the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week)) and 3 months from the last session (16th week)
Change from Confidence in the treatment
Confidence in the treatment evaluated by the Patient Global Impression of Change.
Measured: After the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week)) and 3 months from the last session (16th week)
Change from Global health
Self-reported Global health evaluated by the Short form-36 (SF-36).
Measured: At the start of the study (at baseline, 0 week), after the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week)) and 3 months from the last session (16th week)
Change from Cognitive impairment
Cognitive impairment evaluated by the Multidimensional Inventory of Subjective Cognitive Impairment.
Measured: At the start of the study (at baseline, 0 week), after the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week)) and 3 months from the last session (16th week)
Change from Depression
Depression Evaluated by the Hospital Anxiety and Depression Scale: 14 items, 7 for depression and 7 for anxiety. Each item had been answered by the patient on a four-point (0-3) response category so the possible scores ranged from 0 to 21 for anxiety and 0 to 21 for depression, the worse the result the higher the score.
Measured: At the start of the study (at baseline, 0 week), after the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week)) and 3 months from the last session (16th week)
Change from Sleep
Change from Sleep evaluated by the Medical Outcomes Study Sleep Scale:12 Likert-type items with 6 degrees of response (from 1-always to 6-never). For its interpretation, a gross estimate of the amount of sleep is obtained (item 2) and scores in the different subscales. The direct scores are transformed into a scale from 0 to 100, with no cut-off points; the higher the score, the greater the intensity of the concept evaluated.
Measured: At the start of the study (at baseline, 0 week), after the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week)) and 3 months from the last session (16th week)
Change from Physical activity
Change from Physical activity evaluated by the International Physical Activity Questionnaire.
Measured: After the 10th session (at the end of the second week), after 20th session (at the end of the fourth week), 1 month from the last session (8th week) and 3 months from the last session (16th week)
