Immune Function and Chiropractic in Indianapolis 96th Street Chiropractic in Indianapolis offers this natural treatment for many conditions. Let's take a closer look. One of the most important studies showing the positive effect chiropractic care can have on the immune system and general health was performed by Ronald Pero, Ph.D., chief of cancer prevention research at New York's Preventive Medicine Institute and professor of medicine at New York University. 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. In his initial three-year study 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 people who had not received chiropractic care, and 400% greater immune competence than people with cancer and other serious diseases. The immune system superiority of those under chiropractic care did not 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..." Source: Pero R. "Medical Researcher Excited By CBSRF Project Results."

The Central Nervous System and Immune Response: A study published in 2010 in the Journal of Chiropractic & Osteopathy examined the relationship between the central nervous system and immune response. It measured immunoglobulin G and immunoglobulin M before a chiropractic treatment and after. Study participants were divided into three groups. Those that underwent chiropractic adjustments had significantly higher immunoglobulin levels than those that did not. A previous review of data published in the Chiropractic Journal of Australia in 1993 showed that chiropractic adjustments positively affect immunoglobulin levels.
