First of all, Dr. Smith is an oncologist, not a chiropractor. His study (which showed an average pain reduction of 64%, with 100% pain reduction in 25% of the patients) was published in the Journal of Pain and Symptom Management. Since it has been published in a peer-reviewed medical journal and presented at medical conferences, I would say it science, not blind faith. Dr. Loprinzi and Dr. Campbell are also not chiropractors and have both talked about the effectiveness of the Calmare therapy. You really have done no research on the device, its effectiveness (which I know what it is - do you?), or the pain relief that patients have gotten. In regards to the costs, it can range anywhere from $150 to $250 per session. The patients can decide if it worth the cost or not but I'm sure that they have already spent multiples of that on other sources of pain relief over the years. The total cost of the session would be a fraction of what they would spend on nerve blockers, surgical implants, opiates, etc.
