The first recorded chiropractic adjustment was performed on September 18, 1895, by Dr. Daniel David Palmer, a Canadian-born teacher and helter. Dr. Palmer was, at the time, studying the cause and effect of disease. His patient was Harvey Lillard, a janitor working in the same building as Dr. Palmer in Davenport, Iowa. Mr. Lillard, who had complained of hearing problems for over 17 years, allowed Dr. Palmer to examine his spine. Dr. Palmer discovered a "lump" on Mr. Lillard's back and suspected that a vertebra might be out of place, which he then repositioned the vertebra with a gentle thrust. After several such treatments, much of Mr. Lillard's hearing was restored.
Since Dr. Palmer's first chiropractic adjustment, the art and science of chiropractic has progressed significantly. Today, advanced diagnostic procedures, sophisticated equipment, scientific research, and the growing acceptance among other health care professionals makes chiropractic a popular health care choice
