Postmarketing Survey of effects of Using Alpha-Stim™ Device for CES

Daniel Kirsch, author of "The Science Behind Cranial Electrotherapy Stimulation" (2nd Ed., 2002), includes details in his book of a "Postmarketing survey of Alpha-Stim™ CES patients (page 158)", which reported feedback of 500 CES users:

"Negative side effects were all mild and self-limiting: 472 (94.4%) reported none. 6 (1.2%) reported dizziness as a side effect, and 2 (0.4%) reported nausea, both of which normally occur when the current is set too high or in patients with a history of vertigo, 3 (0.6%) reported skin irritation, and 1 each (0.2%) reported anger, a metallic taste, a heavy feeling, or intensified tinnitus." and that "The most important aspect of this survey was the results reported as a degree of improvement in the seven symptoms present in most patients for which CES is prescribed; i.e., pain, anxiety, depression, stress, insomnia, headache, and muscle tension. A degree of improvement of 25% or greater was considered to be clinically significant."

The combined data for all 500 patients reporting on multiple symptoms is summarized below:
