Dr. Pero measured the immune systems of people under chiropractic care as compared to those in the general population and those with cancer and other serious diseases. His initial three-year study was of 107 individuals who had been under chiropractic care for five years or more. The chiropractic patients were found to have a 200% greater immune competence than those people who had not received chiropractic care, and they had 400% greater immune competence than those people with cancer and other serious diseases. The immune system superiority of those under chiropractic care did not appear to diminish with age. Dr. Pero stated:
When applied in a clinical framework, I have never seen a group other than this chiropractic group to experience a 200% increase over the normal patients. This is why it is so dramatically important. We have never seen such a positive improvement in a group.
Another study from Patricia Brennan, PH.D., leading a team of researchers, conducted a study that found improved immune response in her test subjects following chiropractic treatment. The study specifically demonstrated the “phagocytic respiratory burst of polymorphonuclear neutrophils (PMN) and monocytes were enhanced in adults that had been adjusted by chiropractors.”
