Dr. Roy Sweat, the founder of the atlas orthogonal procedure and considered by many to be one of the foremost authorities in the world on the cervical spine, devised a method using a percussion wave to re-position the atlas vertebra.
The history of treating the atlas goes back to the early 1900’s when Dr. B.J. Palmer, the developer of chiropractic, spent many years of clinical research in discovering that it was the atlas that controlled the position of the head and the resulting position of the rest of the spine. Dr. Palmer taught to correct the atlas position using the hands with @ 40 pounds of force. Dr. Sweat and Dr. John F. Grostic were taught by Dr. Palmer. In his extensive clinical research, Dr. Grostic found that much less force was actually necessary to correct the atlas into position. Dr. Sweat in his further research discovered that even less force was actually needed. Dr. Sweat invented and engineered a highly advanced instrument that without pain or pressure is able to accurately re-position the atlas vertebra.
