When it comes to your spine, “good enough” is never good enough. Spinal decompression can be life-changing for patients with herniated discs, sciatica, degenerative disc disease, or chronic back pain. But here’s a fact that most patients don’t realize: not all decompression systems are equally effective or backed by research.
At Frisco Spinal Rehab, we’ve spent over two decades working with various systems—and we know their strengths and weaknesses. While many clinics only know the table they bought first, we’ve tested a wide range. That experience gives us a rare insight: when it comes to precision, comfort, safety, and research, the DRX9000 stands above the rest in our opinion.
Most traction/decompression systems promote “disc pressure relief,” but very few have measurable proof of negative intradiscal pressure—the true mechanism behind decompression. The VAX‑D system is one of the only devices with in-vivo measurements showing pressures falling into the −100 to −160 mmHg range, confirming the ability to create a true “vacuum effect” inside the disc. This effect draws fluids, oxygen, and nutrients back into the disc space—essential for healing and regeneration.
While the DRX9000 hasn’t been directly tested for intradiscal pressure, its design emulates this proven mechanism—and other clinical outcomes support its effectiveness. Dr. William Martin, a neuroradiologist, was one of the coleaders in the Vax-D study and utilizes the DRX9000 in his personal practice due to the advances it made from the original VAX-D system.
A 2025 case series from University of South Florida demonstrated not only symptom relief but also image-confirmed anatomical changes after DRX9000 treatment. In 13 patients receiving 20 sessions, MRIs showed:
Disc height increased by 1.0–1.6 mm
Anterior–posterior (AP) canal dimensions increased by 1.5–2.1 mm
Pain improved by 80%, disability improved by 50%, and subjective recovery was 75%
This study is especially meaningful because it correlates structural changes with clinical improvement.
Apfel et al., BMC Musculoskeletal Disorders (2010): A retrospective cohort of 30 patients showed disc height increased from 7.5 mm to 8.8 mm (p < 0.001). This increase in disc height was significantly correlated with pain reduction (r = 0.36, p = 0.044)
2019 comparative study: Patients treated with DRX9000 showed a greater improvement in disc height (MRI) and radicular pain versus a typical physiotherapy/traction control group
We’ve worked with numerous decompression systems. Many produced inconsistent results or patient discomfort. We chose to invest in the DRX9000 after seeing the clear difference—precise control, comfort, an intuitive protocol, and clinical evidence that supports real anatomical and functional outcomes—not just marketing.
Comfort and Compliance: We’ve seen many patients complete their protocols fully—no interruption due to discomfort.
Safety Features: The DRX9000 adjusts in real-time to muscle guarding, minimizing the risk of injury and making it safe even for patients with complex spine conditions.
| Study & Year | Key Findings |
|---|---|
| Ramos & Martin (1994, J Neurosurgery) | Proven negative intradiscal pressure of −100 to −160 mmHg in VAX‑D system |
| USF 2025 (J Contemporary Chiropractic) | DRX9000 improved disc height (+1.0–1.6 mm) and AP dimension (+1.5–2.1 mm), with pain and disability significantly reduced |
| Apfel et al. (2010, BMC) | DRX9000 increased disc height (7.5 → 8.8 mm), correlated with pain relief |
| 2019 Comparative Study | DRX9000 showed greater disc height improvement and radicular pain reduction versus physiotherapy/traction |
If you’re going to invest in spinal decompression, don’t settle for machines without measurable outcomes. At Frisco Spinal Rehab, we’ve seen firsthand what works—and what doesn’t. That’s why we’ve chosen the DRX9000, backed by imaging studies, clinical outcomes, and decades of experience.
Spinal decompression isn’t for everyone, and results vary. That’s why our process starts with a detailed consultation and MRI review. But when it’s the right path for patients, choosing the gold-standard system—backed by research, tested by us, and proven to deliver—makes all the difference.
Call Frisco Spinal Rehab today to schedule your consultation and MRI review—and experience the science-backed decompression difference with the DRX9000.
