Noninvasive Brain Electrical Stimulation Lacks Effectiveness in Fibromyalgia, Study Suggests
Researchers found that the use of brain electrical stimulation as a way to modulate pain, depression, anxiety, or insomnia lacks clinical evidence demonstrating its benefits. The study, "Benefits and Harms of Cranial Electrical Stimulation for Chronic Painful Conditions, Depression, Anxiety, and Insomnia: A Systematic Review," was published in the Annals of Internal Medicine. Cranial electrical stimulation (CES) is a noninvasive technique in which electric stimulus is delivered to the brain to change the way brain cells are working. The use of such strategy has been growing, and is commonly used to treat diseases like depression, anxiety, and insomnia. CES has also been shown to have the potential to ease pain in patients with chronic conditions such as fibromyalgia. CES devices are available in the United States by prescription only. However, in some other countries such devices can be purchased directly to manufactures. Also, second-hand devices are accessible through internet-based auctions. This easy access highlights the need for better evidence of the benefits and harms of CES. A team led by researchers at the West Los Angeles Veterans Affairs Medical Center reviewed clinical data collected from 26 randomized trials that evaluated the safety and efficacy of CES to treat pain, depression, anxiety, and sleep disturbances.
