Mindgrowth, a U.S.-Canadian company – distributes biofeedback equipment – with 
and without tracking software – used for, among other things, pain management/reduction, treating PTSD, panic disorders, and other uses.The GSR2 (pictured below) is designed and manufactured in North America by Thought Technology, the largest manufacturer of biofeedback products in the world. There are more than 550,000 of the GSR2 in use worldwide, including the United States Veterans’ Administration medical system.
Biofeedback is no longer “experimental” – there’s no question that it works, not only for medical uses, but also in enhancing athletic performance and cognitive function. It has a substantial drawback in the context of the United States health system: once purchased, and used/learned, some people have lasting effects and never touch the equipment again – others need to return to the biofeedback equipment to “relearn” the original “lesson.” To keep this example simple – think of someone trying to unlearn a fear response to a particular stimulus – loud noises, for example.
