I'm going back to my pain doc in two weeks for CES. I had never heard of this so I looked it up. Has anyone else tried it? Did it work? Here's what I found about the therapy: It appears that CES influences areas of the brain called the thalamus, hypothalamus and the reticular activating system. It also seems to stimulate the vagus nerve, producing a state of parasympathetic nervous system dominance. The parasympathetic nervous system has a general calming effect on the body. This is certainly consistent with the effects observed with CES. CES has been documented to normalize the body’s electrical fields. This has been measured on EEG (brain wave tracing). For example, people with moderate to severe pain from osteoarthritis were found to have abnormal brain wave activity. After five minutes of CES treatment, brain waves were virtually normal and pain was reduced by more than fifty percent. It has been found that individuals whose brain waves improved the most had the greatest pain relief. It is postulated that CES restores normal electromagnetic communication between cells. This may have the effect of regulating cellular differentiation, tissue repair, and immune function.
