What is Expanding Ellipsoidal Decompression (EED®) and how does it relieve neck & back pain?

Neck & back pain is a very common problem among the US population, and has traditionally been treated with the use of drugs. However, there are now therapeutic options like the Posture Pump® Disc Hydrator®, which uses Expanding Ellipsoidal Decompression (EED®) to ease painful stiffness of the neck and back. But what is Expanding Ellipsoidal Decompression, and how does it alleviate neck and back pain?

Short term neck and back pain very often resolves on its own. However, chronic pain due to conditions such as sciatica, sciata, disc degeneration, compressed discs and herniated discs, usually require intervention. In these cases, Posture Pump® products provide a unique form of decompression therapy known as EED® for relief of neck & back pain.

What is Expanding Ellipsoidal Decompression (EED®))?

EED® was invented and patented by Posture Pump®.  Under EED®, high level joint separation is achieved by expansion of elliptical shaped air cells into the curves of the spine (neck & back).  As EED® occurs, bulging disc material is drawn toward the nucleus pulposus and away from the spinal cord and nerves.  This unique action aligns joints in a curved shape while increasing disc height in a ratio corresponding to the disc’s natural wedged shape. Expansion and contraction of these air cells create alternating hydration and milking of the discs.  Longer expansion periods are employed for posture decompression and shaping. It is no longer necessary to forcefully pry the head from the body, pull the posterior joints apart and remove the vital curves of the neck and back.  These spinal curves are essential.

Posture Pump MRI

Most healthcare professionals are choosing to treat patients with neck & back pain using EED® via Posture Pump®, because it does not forcefully remove the vital natural curves of the spine. This is not the case with conventional linear traction treatment, which tends to remove the essential spinal curves.  In an IRB approved MRI study conducted by Dr. C. Norman Shealy, M.D., Ph.D., neurosurgeon, researcher and author, he found that Posture Pump® Cervical Disc Hydrator® improved the cervical curve in 72% of subjects whereas the commonly used form of linear traction device had only an 8% cervical curve improvement.  In fact, linear traction actually compromised the cervical curve in 83% of subjects.  Dr. Shealy also found that Posture Pump® increased the average disc height twice as much than with the linear traction device.  You can view this and other research studies here.
