Back and neck pain are among the most common reasons people seek medical or therapeutic care. In cases involving spinal disc issues—such as herniated discs, degenerative disc disease, or sciatica—one non-surgical treatment option that’s gained widespread attention is spinal decompression therapy. This post explains what spinal decompression therapy is, how it works, how it differs from surgical alternatives, and what patients can expect during a typical course of treatment.
What Is Spinal Decompression Therapy?
Spinal decompression therapy is a non-invasive treatment that uses controlled mechanical traction to gently stretch the spine. The goal is to relieve pressure on the intervertebral discs, spinal nerves, and surrounding structures.
This decompression process is proven to:
- Create negative pressure within spinal discs
- Encourage retraction of herniated or bulging disc material
- Improve the flow of oxygen, water, and nutrients into the discs to support healing
Unlike traditional traction, spinal decompression therapy involves computer-controlled cycles of stretch and relaxation, which are tailored to the patient’s needs.
Conditions That May Benefit
Spinal decompression therapy is often considered for patients experiencing:
- Herniated or bulging discs
- Degenerative disc disease
- Sciatica or nerve root compression
- Facet syndrome
- Chronic lower back or neck pain
While it’s not a solution for every type of spinal issue, it may be a helpful conservative option for patients who want to avoid or delay surgical procedures.
How It Works: Step-by-Step
During a session, the patient lies on a motorized table that can be adjusted to target either the cervical (neck) or lumbar (lower back) spine. The patient is fitted with a harness or cradle, depending on the treatment area. Once in place, the machine applies a gentle traction force to slowly stretch the spine.
The therapy typically alternates between phases of pulling and relaxation over a period of about 15 to 30 minutes.
The key mechanism is the reduction of pressure within the disc space, which may create conditions that promote disc healing or rehydration. The repeated cycles of decompression and rest are designed to mimic the body’s natural motion while providing therapeutic benefits.
Non-Surgical vs. Surgical Decompression
While spinal decompression therapy is often grouped with other conservative treatments like physical therapy or chiropractic care, it’s fundamentally different from surgical decompression procedures.

Surgical decompression procedures—such as laminectomy or discectomy—may be necessary in more severe cases or when conservative care hasn’t produced meaningful results. Spinal decompression therapy, by contrast, is often used as a first-line or intermediate option.
What to Expect During Treatment
Spinal decompression is usually performed in a clinical setting and is customized to each individual. Here’s what a typical treatment course involves:
- Session Length: 15 to 30 minutes
- Frequency: Commonly 2–3 times per week
- Duration: Often involves 12 to 20 sessions over several weeks
During the session, most patients feel a mild pulling or lengthening sensation in the spine. It’s generally described as comfortable—some even find it relaxing. The table’s movement is slow and computer-controlled to prevent any sudden or jarring motions.
Afterward, patients may feel temporary soreness or fatigue, especially during the early sessions, similar to how one might feel after physical activity.
Safety & Candidacy
Spinal decompression therapy is FDA-cleared for certain spinal conditions and is generally considered safe for most individuals. However, it may not be suitable for people with:
- Severe osteoporosis
- Spinal fractures
- Spinal implants or fusion hardware
- Abdominal aortic aneurysm
- Pregnancy
A thorough evaluation is recommended before beginning treatment. Most healthcare providers will assess your medical history, symptoms, and (when necessary) imaging results to determine if decompression is appropriate.
Complementary Therapies
Spinal decompression therapy is often used alongside other non-invasive treatments to improve outcomes. Depending on the provider, this may include:
- Chiropractic care to improve spinal alignment
- Shockwave therapy to break through adhesions/scar tissue
- Soft tissue therapy to reduce muscle tension
- Cold laser therapy to reduce inflammation
- Therapeutic exercise or physical rehab to strengthen supporting musculature
Using a multimodal approach can help address not just the symptoms but also the contributing factors to chronic spinal discomfort.
Evidence & Considerations
Research into spinal decompression therapy is ongoing. Some clinical studies and case reports suggest that patients with herniated discs or sciatica may experience symptom relief and functional improvement. However, it’s important to note that individual results vary, and more high-quality studies are still needed to establish long-term efficacy across all patient groups.
As with any treatment, open communication with a qualified provider is key. Patients are encouraged to ask questions, set realistic expectations, and monitor their progress throughout the process.
Final Thoughts
Spinal decompression therapy offers a non-surgical option for individuals dealing with disc-related back or neck pain. By reducing pressure within the spinal column and promoting fluid exchange, this therapy aims to create an environment that supports healing. It’s most appropriate for certain conditions like herniated discs, sciatica, or degenerative disc disease, and it may be used as part of a broader care plan that includes physical therapy or manual treatments.
If you’re considering decompression therapy, consult with a licensed provider to determine whether it’s a good fit for your condition and overall health profile.
