Quick answer
Flexion-distraction is a slow, hands-on chiropractic technique for low back pain, including pain from a herniated disc and sciatica. You lie face down on a special table while the doctor gently bends and stretches your low back. The goal is to ease pressure on the disc and the nearby nerve without surgery. Results vary.
At a glance
What it is: A slow, gentle stretch-and-bend technique for the low back, done on a special table.
Who it’s for: People with disc-related low back pain or pain that runs down the leg, like sciatica.
What it involves: Lying face down while the lower part of the table moves and the doctor guides your back by hand.
Most people with a herniated disc never need surgery. Flexion-distraction is one hands-on, non-surgical option we use that aims to take pressure off the disc and the nerve.
What is a herniated disc, and how does it cause sciatica?
A herniated disc happens when the soft center of a spinal disc pushes out through a tear in its tougher outer ring. The discs are the rubbery cushions between the bones of your spine. You might also hear it called a slipped or ruptured disc.
It’s most common in the low back, and if the disc presses on a nearby nerve, you can feel pain, numbness or tingling in your buttock, thigh or calf, and sometimes all the way to your foot. When that pain runs down your leg, most people call it sciatica.
What is flexion-distraction therapy?
It’s a slow chiropractic technique that gently bends and stretches your low back on a special table while you lie face down. The doctor keeps a hand on the part of your back being treated as the lower half of the table moves in a slow, steady rhythm.
There’s no quick twist or thrust, just slow, controlled motion. You can see how we use flexion-distraction at our office and the back problems we treat with it.
How might it help a herniated disc or sciatica?
The idea is to take pressure off the disc and the nerve it’s pressing on. As the table bends your low back forward, it opens up space at the back of the spine. That lowers the pressure inside the disc.
Less pressure on the disc can mean less pressure on the nerve, and the nerve is where sciatica pain comes from. The motion also aims to get stiff joints in your low back moving again. It doesn’t work the same way for everyone.
Who is it for, and who should skip it?
You may be a good fit if your low back pain or leg pain comes from a disc or a stiff, narrowed spine. It’s used for pain and stiffness linked to:
- Herniated, bulging or “slipped” discs in the low back
- Sciatica
- Spinal stenosis (a narrowing of the spinal canal)
- Spondylolisthesis (a vertebra that has slipped forward)
- Sacroiliac (SI) joint problems
- Arthritis in the low back
It isn’t the right choice if you have:
- Severe osteoporosis
- A broken bone in your low back
- A back fusion that failed and left the hardware unstable
- An active infection in the area
Some symptoms need emergency care first. Go to the ER if you have trouble controlling your bladder or bowels, numbness in your inner thighs or around your rectum, or leg pain, numbness or weakness that keeps getting worse. That’s why we start with an exam before any treatment.
What are the sessions like?
They’re calm and slow, and the table moves in a gentle, steady rhythm with no force behind it.
The doctor sets your plan, including how long each treatment runs and how often you come in, based on your exam and how your back responds. For comparison, a research trial on flexion-distraction used treatments of 3 to 6 minutes, 2 to 4 times a week for four weeks. That was the study’s schedule, not a standard one.
Quick answers
Does flexion-distraction work for sciatica?
It can help. In a randomized trial of 235 adults with long-term low back pain, people who got flexion-distraction had more pain relief after four weeks than people on an exercise program. People whose pain ran down the leg did especially well with it, though that group was smaller. Results vary from person to person.
Is flexion-distraction safe with a herniated disc?
For many people, yes. The motion is slow and gentle, with no quick thrust, and nobody in that four-week study reported a side effect from it. It isn’t a fit for everyone, though, so check the list above, and tell the doctor right away if any movement doesn’t feel right.
Is flexion-distraction the same as spinal decompression?
No, though both aim to take pressure off your discs. With flexion-distraction, the doctor guides your low back by hand while the table bends it. With spinal decompression, you’re fitted with a harness and the table slowly stretches your spine.
Can you do flexion-distraction at home?
Not really. It depends on a special table and a doctor trained in the technique guiding your back, so it’s an in-office treatment.
