Dr. Cox explains Flexion-Distraction (also known as Cox Technic), as a marriage of chiropractic principles with the osteopathic principles set forth by Alan Stoddard, DO, in his book, Manual of Osteopathic Technique, written about the manipulative procedures developed by John McManis, DO, in the early 1900's. Since the early 1970's, Dr. Cox has refined and improved the technique. Flexion-Detraction is an excellent technique to treat low back conditions such as sciatica, degenerative disc disease and bulging disc problems.
