OBJECTIVE: To evaluate the effectiveness and safety of transcranial direct
current stimulation for fibro-myalgia. METHODS: Databases, conference records and
registered trials were searched for articles published from the date of
establishment of the database through to October 2015. Six randomized controlled
trials (n=192) of transcranial direct current stimulation for fibromyalgia were
included in the current study. DATA EXTRACTION: Two researchers independently
screened the literature, assessed methodological quality using the Cochrane
Collaboration's tool, and extracted data. DATA SYNTHESIS: Studies were divided
into 3 groups for meta-analysis according to stimulation site and polarity.
Significant improvement in pain and general fibromyalgia-related function was
seen with anodal transcranial direct current stimulation over the primary motor
cortex (p<0.05). However, the pressure pain threshold did not improve (p>0.05).
Anodal transcranial direct current stimulation over the left dorsolateral
prefrontal cortex did not significantly reduce pain or improve general
fibromyalgia-related function compared with sham stimulation (p>0.05). Cathodal
transcranial direct current stimulation over the primary motor cortex did not
improve the pressure pain threshold compared with sham stimulation (p>0.05). No
significant adverse effects were seen. CONCLUSION: Anodal transcranial direct
current stimulation over the primary motor cortex is more likely than sham
transcranial direct current stimulation to relieve pain and improve general
fibromyalgia-related function.
