New Research Demonstrates Significant Improvements in Cervical Disc Height and Neck Pain Following Posture-Focused Spinal Rehabilitation
Study published in Bioengineering suggests Chiropractic BioPhysics® improves spinal alignment, disc morphology, and patient outcomes
Eagle, Idaho — February 24, 2026
A groundbreaking retrospective case series published in the peer-reviewed journal Bioengineering (a Q2 journal from MDPI) provides compelling evidence that structural spinal rehabilitation can do more than just manage pain—it can physically improve the integrity of the cervical spine. The study, titled “Increased Cervical Disc Height and Decreased Neck Pain and Disability Following Improvement in Cervical Lordosis and Posture Using Chiropractic BioPhysics®,” highlights a significant medical breakthrough for the chiropractic profession.
The study followed 64 patients who had previously sought relief through traditional chiropractic, physical therapy, or medical intervention without success. By utilizing the specific protocols of Chiropractic BioPhysics® (CBP®)—including Mirror Image® adjustments, corrective exercises, and cervical extension traction to restore the cervical lordotic curvature—researchers observed measurable physiological changes in the spinal discs.
Key Highlights for the Chiropractic Practitioner:
- Disc Height Restoration: The study documented a statistically significant increase in both anterior and posterior cervical disc heights (C2–C7) following the restoration of the cervical lordosis.
- Structural-Functional Connection: Improvements in the cervical “arc” (lordosis) were directly correlated with a reduction in patient-reported neck pain (NRS) and disability (NDI).
- Overcoming “Plateaued” Patients: Participants in the study were those who had failed to improve under “standard” care, suggesting that structural correction is a vital missing link for chronic cases.
Validated Outcomes: Using the Harrison Posterior Tangent Method to measure cervical curve and a reliable and valid measurement of disc height, the study confirms that restoring the spine’s sagittal alignment facilitates a better environment for disc health and nutrient exchange.
A Quote from Lead Author, Dr. Evan Katz
“For decades, the profession has debated whether we can truly impact the structural integrity of the intervertebral disc. This research provides a definitive ‘yes.’ By restoring the natural lordotic curve of the cervical spine, we aren’t just masking symptoms; we are changing the mechanical environment of the spine. We saw significant increases in disc height across the board, proving that when you fix the structure, the biology follows. This is a game-changer for how we communicate the value of corrective chiropractic care to both patients and the wider medical community.”

About the Study:
The research utilized a retrospective analysis of patients treated with CBP® protocols. The findings suggest that by addressing the global spinal alignment rather than just segmental motion, clinicians can achieve objective, radiographic improvements in degenerative disc disease markers.
