For centuries, crude types of spinal manipulation were practiced all over the world, until Daniel David Palmer discovered the specific spinal adjustment. He is most noted for correcting the spine of a man named Harvey Lillard, who had been deaf for 17 years. An examination showed a vertebrae was moved from its normal position; D.D. Palmer believed repositioning this vertebra would restore this man's hearing. In one chiropractic treatment, his hearing was restored. This adjustment pioneered the way for chiropractic care throughout the U.S. and the world.
