Fibromyalgia is a multisymptomatic diffuse chronic musculoskeletal pain syndrome with evidence of central nervous system dysfunction.
Fibromyalgia
is characterized by widespread musculoskeletal pain accompanied by
fatigue, sleep, memory and mood issues. In this review, Deus-Yela J
et al. used a novel non-invasive transcranial direct current
stimulation (tDCS) technique and reported the significant reduction
in symptoms of fibromyalgia.
Fibromyalgia
is a multisymptomatic diffuse chronic musculoskeletal pain syndrome
with evidence of central nervous system dysfunction. Accordingly,
non-invasive brain stimulation techniques for example transcranial
direct current stimulation (tDCS) may be a complementary therapeutic
resource to decrease the pain perception.
This review depicts the
potential effectiveness of tDCS to reduce pain in fibromyalgia and
identify the most effective neurostimulation parameters and delimit
its safety.
Systematic review of prospective studies reported in PubMed and Cochrane reviews.
The
anodal tDCS of the left primary motor cortex, at 2mA for 20 minutes
with 35 cm2 electrodes on five consecutive days, provides better
results in reducing pain (14-59%), and improves the sleep quality,
with greater accentuation on the fifth day. The clinical improvement
lasts up to a minimum of 60 days (11-20% reduction of pain). Adverse
effects are well tolerated and few.
The experience with tDCS in fibromyalgia is still limited.But, the anodal tDCS in the left primary motor cortex can be suggested with level B (probable therapeutic efficacy) and appears to act through the modification of the sensorial processing of the pain of thalamic inhibitory circuitry.
