    Thirty-six (36) individuals with complaints of cervical pain were evaluated with MRI’s at rest, as well as during the application of Axial Linear Traction and Expanding Ellipsoidal Decompression (EED®).  Both devices significantly decreased the magnitude and instance of anterior subarachnoid protrusions: EED® in 86% of subjects, Linear Traction in 71%.  Ranges of motion were improved by both devices with the greater improvement generally being attributed to the device applied last.

    EED® expanded disc height on average over twice as much as Linear Traction. While both EED® and Linear Traction increased the posterior disc height an average of 19%, Linear Traction frequently compressed the anterior and center of the disc in relation to the neutral (no device applied) scan.  In contrast, EED® expanded the entire disc including the central and anterior regions in a balanced ratio that seems to mirror the natural wedged shape found in normal cervical discs.

    Key Words:  Axial Linear Traction (ALT); Expanding Ellipsoidal Decompression (EED®); disc bulges

    Key Points:

    - Disc height increased more with EED®

    - Range of motion improved with EED® and ALT

    - EED® optimizes natural cervical curve
