If you’ve been researching spinal decompression, you’ve probably noticed a lot of conflicting claims. Some clinics promote “decompression” that’s really just traction, while others use advanced systems like the DRX9000 that are backed by research. Patients also ask whether inversion tables can provide the same results.
To clear up the confusion, we’ve compiled the most common questions patients ask about disc pressure, decompression research, and why not all tables are created equal.
Your spinal discs act like cushions between the bones of your spine. They’re always under pressure—lowest when lying down (~25 mmHg), higher when standing (~100 mmHg), and highest when sitting (~125–150 mmHg).
When a disc is herniated or degenerating, these pressures push material outward into nerves, creating pain, numbness, or weakness. Lowering that pressure is the key to disc healing.
Research shows that advanced systems like the DRX9000 can lower intradiscal pressure into the negative range (–100 to –160 mmHg). This vacuum effect helps retract herniated material, rehydrate the disc, and promote structural healing—not just temporary pain relief.
The DRX9000 uses a logarithmic pull curve that adjusts 13 times per second to prevent muscle guarding. Unlike “me too” tables, it has published research showing:
True negative disc pressure
Disc height restoration
MRI-verified herniation shrinkage
Other tables may look similar, but they don’t create the same healing environment.
Inversion tables may temporarily reduce pressure but never below zero. Even upside down, intradiscal pressure stays around 25–40 mmHg—so there’s no vacuum effect to pull herniations back in.
Inversion may help some people feel looser, but the relief is short-lived and it’s not safe for everyone (especially patients with glaucoma, heart conditions, or high blood pressure).
Yes. Published research and imaging studies show:
Disc height increases of 1–1.6 mm
Spinal canal space widening up to 2 mm
Pain improvements averaging 80%
Herniation regression, with some discs fully resolving
This makes decompression more than symptom relief—it’s measurable, structural healing.
Most of those studies had limitations:
Too few sessions (10–15 instead of the 20–30 needed for real change)
Mixed patient groups (general back pain instead of herniated disc cases)
Limited outcomes (pain scores only, without MRI follow-up)
When done properly, decompression consistently outperforms traction.
Most patients require 20–30 decompression sessions over several weeks. This allows the discs to heal structurally and provides lasting improvement, rather than just temporary relief.
Yes. The DRX9000 is FDA-cleared, non-invasive, and comfortable. Because the pull is computer-controlled and constantly adjusting, it avoids the sudden tugs that can trigger muscle guarding. Most patients find the sessions relaxing.
Everyday life loads your discs with constant pressure. Only true spinal decompression systems like the DRX9000 can reverse that pressure into the negative range, creating an environment proven to retract herniations and restore disc health.
Other tables or inversion devices may stretch your back, but they don’t heal discs. If you want lasting results—not just temporary relief—choose true spinal decompression.
If you’re struggling with a herniated disc, sciatica, or chronic back pain, don’t settle for temporary relief. Call Frisco Spinal Rehab today at 972-712-7744 to schedule your consultation.
