Case Study Report: The Treatment of 100 Cases With Articulating Traction Decompression & Specific Patient Posturing (2008)

David Bass, D.C. & Scott Denny, Ph.D., D.C.

Landmark multicenter clinical retrospective documenting 100 consecutive cases of severe disc herniation, spinal stenosis, and radiculopathy treated with 10-way articulating decompression on Antalgic-Trak. Over 90% of patients achieved significant to complete relief with restored spinal range of motion and averted planned surgical intervention.

Case Study Report: The Treatment of 100 Cases With Articulating Traction Decompression & Specific Patient Posturing — 12-Month Follow-Up (2009)

David Bass, D.C. & Scott Denny, Ph.D., D.C.

One-year follow-up of the original 100-patient Antalgic-Trak cohort. Results confirmed sustained long-term efficacy with 89% maintaining their pain relief, zero late-onset complications, and continued avoidance of lumbar spine fusion or discectomy surgery.

Effects of Vertebral Axial Decompression on Intradiscal Pressure

Gustavo Ramos, M.D. & William Martin, M.D.

The groundbreaking Journal of Neurosurgery study providing in vivo proof of negative intradiscal pressure during decompression. Intra-cannular pressure sensors in L4-L5 demonstrated negative pressures dropping to -100 to -160 mmHg, proving the physiological suction phenomenon that draws herniations inward.

Prospective Randomised Controlled Study of Spinal Decompression for Lumbar Radiculopathy

G. Gose, Ph.D., W. Naguszewski, M.D., et al.

Peer-reviewed clinical trial published in the Journal of Neurological Research. Documented statistically significant reductions in VAS pain scales and Oswestry Disability Index scores across hundreds of patients suffering from MRI-confirmed disc herniation and DDD.

Edward L. Eyerman, M.D.

High-resolution serial pre- and post-treatment MRI scans documenting up to 50% to 100% reduction in herniated disc volume, re-expansion of dehydrated disc spaces, and widening of narrowed neuroforaminal canals following completion of decompression protocols.

SCIENTIFIC MECHANISM OF ACTION

Why Articulating Decompression Outperforms Flat Traction Tables

Traditional traction tables apply linear, one-dimensional tension while the patient lies flat. In contrast, clinical biomechanics demonstrates that disc herniations lateralize, creating asymmetrical nerve root impingement and involuntary muscle spasm. Antalgic-Trak® is engineered to address these complex clinical dynamics:

❌ Flat Linear Cable Pulls
Linear tension pulls only parallel erector spinae fibers. When patients present with antalgic lean, flat pulling triggers protective muscle guarding and reflexive intradiscal pressure spikes.
✅ Antalgic-Trak® 10-Way 3D Motion
Clinicians can position patients into their antalgic pain-relief vector before decompression starts, gently separating angled paraspinal muscles (multifidi, rotatores) and facet joints.
✅ Negative Pressure Fluid Dynamics
Sub-atmospheric intradiscal pressure (down to -160 mmHg) generates a mechanical vacuum that draws extruded nucleus pulposus material back into the disc and encourages capillary blood flow.
