Flexion Distraction (also know as Cox Technique) is a chiropractic technique used to treat many conditions of the lumbar spine (lower back). It is a non-surgical technique aimed at increasing spinal motion and improving overall function by reducing disc bulges and disc herniations. The treatment is a safe, gentle, non-force procedure and works well to take pressure off the lumbar spinal and supportive structures.


  • Reduce pressure on the spinal nerves from a disc bulge or herniation
  • Increase spinal motion within the disc and spinal joints
  • A conservative option to surgery for herniated discs
  • Reducing symptoms of sciatica

Dr. Sellari had graduate and post graduate training on this technique. During his time at National College of Chiropractic, he had the pleasure of receiving instruction from the techniques developer Dr. James Cox.


Flexion Distraction involves using a special table that distracts and flexes the spine in a gentle rythmic motion. Dr. Sellari uses some manual techniques with the table to resolve the disc herniation or bulge. The goal is to enhance or restore normal joint motion and remove pressure from the disc bulge or herniation. It does this by creating a negative pressure that pulls the disc material back into the spine. The flexion distraction motion also maintains healthy discs, ligaments and spinal joints. The motion allows nutrients into the spinal disc and keeps the normal muscle and ligament flexibility.


Flexion Distraction (Cox Technique) has an impressive foundation of spine care research that supports its use. Case reports and a series of online and published journal articles are available. There are also published federally funded biomechanical studies and high-level randomized clinical trials, In the largest data collection of low back pain outcomes (1000 cases), a mean of 12 visits in 29 days to relieved pain. For cervical spine, 13 visits was the mean.
