Abstract:
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

[…] Pain in the cervical spine or neck is more common than ever, especially because of the poor posture when using smartphones and other modern mobile devices. It’s well known that good posture is better for your back, while bad posture stresses the cervical spine, and leads to early degeneration. So how do you alleviate cervical pain? […]
