This treatment is frequency specific microcurrent. There are many microcurrent treatments available but Dr McMakin pioneered this particular one and has trained hundreds of docs, but I suspect she has a special healing touch that other lack. I personally witnessed the reversal of my friends RSD, to the amazement and dismay of the neurosurgeons in Boise, and she told of her support groups success also. I don't think Dr McMakin would claim to get the level of success on all RSD patients that she did with my friend, because that case was used for an article in a medical journal. But please do not dismiss this as quackery; it has worked a miracle. I would recommend anyone with RSD, fibermyalgia or other neural pain issues to call Dr McMakin **and she will give you the straight story on expectations.
