Is your "decompression" really just traction?
Many treatments call themselves spinal decompression, but they're actually just traction. Knowing the difference could save you time, money, and unnecessary pain.
I see this confusion every week in our clinic.
Patients come in after trying "decompression" somewhere else, and they're frustrated because they felt a pull, maybe some temporary relief, but then the pain came back and they're left wondering what happened.
Here's what many people don't realize.
Traditional traction pulls on your spine with steady or intermittent force using belts, harnesses, and pulleys. It's a generalized approach that affects your entire spine without targeting the specific disc that's injured.
And here's the real challenge... your body fights back.
When traction pulls, your muscles contract protectively. These reflexive spasms can actually increase disc pressure. Your nervous system is working against the treatment.
Advanced computerized decompression works differently.
Systems like SpineMED measure your body's resistance every 20 milliseconds and make micro-adjustments hundreds of times per minute. Think of it like picking a lock versus forcing a door open.
Traction uses brute force and meets resistance.
Computerized decompression makes hundreds of tiny adjustments until your body relaxes and allows the disc space to open. When the system detects muscle guarding, it instantly backs off a fraction of the pull, then reapplies decompression in a gentler way, sneaking past your body's protective reflexes.
This process repeats continuously, so your nervous system never triggers the defensive muscle contractions that sabotage traditional traction.
The result?
True negative pressure inside the disc space. This vacuum-like environment draws water, oxygen, and nutrients back into damaged discs, creating conditions that support healing.
The difference shows up in recovery stories.
Traction patients often say: "It feels like a stretch. I feel looser for a few hours, but the pain creeps back."
Decompression patients report something different: "After a few weeks, I could walk farther, sit longer, and my constant leg pain became occasional."
Research shows computerized decompression can achieve significant reductions in herniation size. More importantly, many patients experience improvements in daily function: sitting through work days, lifting groceries, sleeping through the night again.
So how do you spot real decompression technology?
Some clinics advertise "decompression" when they're offering traction. You can protect yourself by asking specific questions.
Is the table computer-controlled with continuous feedback, or does it apply preset force? Advanced decompression systems measure patient resistance thousands of times per second, while traction typically uses static or intermittent force without real-time adaptation.
How does the device isolate the exact disc level that's injured? Advanced decompression tables can angle and program force vectors to focus on specific segments like L4-5, whereas traction typically affects the entire spine.
What prevents my muscles from tightening against the pull? If they can't explain real-time force modulation and muscle guarding prevention, that's an important distinction to understand.
And finally, is this system FDA cleared as a decompression device or traction equipment? This distinction matters because decompression systems undergo different regulatory evaluation.
A few more things worth knowing.
Even advanced decompression systems have appropriate applications and limitations. Computerized decompression works best for patients with disc-specific pathology like herniations, nerve root compression, radiculopathy, or sciatica that hasn't responded to conservative care.
No approach works for everyone. Fractures, high-grade instability, spinal tumors, and active infections are contraindications for both treatments. Results vary from patient to patient, and success depends on proper diagnosis, precise disc targeting, and adherence to treatment protocols.
The gentleness of true decompression therapy often surprises patients.
They expect to feel significant pulling, but the most important healing happens when you feel almost nothing... that lack of sensation signals the system is working correctly, bypassing muscle guarding and creating the negative pressure environment discs need to heal.
Before committing to any decompression treatment, ask those revealing questions.
Ask for explanations about real-time adaptation, segmental targeting, and research validation. Understanding how the system measures and adapts to your body continuously helps you make an informed decision.
Your spine deserves precision.
