What Is the Antalgic-Trac Machine?

Quick Answer: The Antalgic-Trac is an FDA-cleared motorized spinal decompression device that applies precise, controlled traction forces to specific segments of the spine. It's used to treat herniated discs, sciatica, degenerative disc disease, and related conditions — without surgery or medication. McNamara Chiropractic Center uses the Antalgic-Trac as the cornerstone of our spinal decompression program.

The Full Answer

If you've been researching spinal decompression therapy, you may have come across the Antalgic-Trac system. It's one of the most clinically sophisticated traction devices available in chiropractic care, and it's a centerpiece of how Dr. McNamara treats spinal disc conditions at our Lighthouse Point office.

What Makes the Antalgic-Trac Different

Traditional traction tables pull the spine in a single direction — axially — which distributes the decompression force across many spinal segments at once. The Antalgic-Trac takes a more targeted approach. Using adjustable angles and computer-controlled distraction cycles, it can:

• Target specific vertebral levels — Instead of pulling the whole spine, the device can be angled to preferentially decompress L4-L5 or L5-S1, for example, which are the most common sites of disc herniation
• Use intermittent distraction cycles — The machine pulls, then releases, then pulls again in a rhythmic pattern. This pumping action is more effective at creating negative intradiscal pressure than sustained traction
• Apply precise force levels — Treatment parameters are set based on your body weight, condition, and tolerance, and adjusted as you progress through the program

How the Antalgic-Trac Works

The treatment works through a mechanism called intradiscal decompression. When the spine is placed under controlled negative pressure:

1. Herniated disc material retracts — The suction-like negative pressure inside the disc pulls bulging or herniated material back toward the center of the disc, away from the nerve root
2. Nutrients and hydration are drawn in — Discs don't have their own blood supply; they depend on this pumping action to receive oxygen, water, and healing nutrients
3. Nerve compression is reduced — As the disc rehydrates and the herniation reduces, pressure on the adjacent nerve roots decreases, relieving pain, numbness, and radiating symptoms
4. Healing is stimulated — The influx of nutrients supports the disc's natural repair process over time

Conditions Treated with the Antalgic-Trac

Dr. McNamara uses the Antalgic-Trac system to treat:

• Herniated or bulging discs (cervical and lumbar)
• Degenerative disc disease
• Sciatica and radiating leg pain
• Spinal stenosis
• Facet syndrome
• Failed back surgery syndrome (post-surgical pain)
• Neck pain with or without arm symptoms

Is the Treatment Painful?

No. Most patients find the Antalgic-Trac sessions comfortable and even relaxing. You'll feel a gentle stretching sensation as the table applies traction. If any position feels uncomfortable, our team adjusts the parameters immediately. Sessions typically last 20 to 30 minutes.

How Many Sessions Will I Need?

Most patients complete 12 to 20 sessions over 4 to 6 weeks, depending on the severity of the condition. Many patients experience noticeable improvement within the first week of treatment.

Is It Safe?

Yes. The Antalgic-Trac is FDA-cleared and has been used in clinical settings for years. It is not appropriate for patients who are pregnant, have spinal fractures, have certain types of implants, or have specific types of spinal instability. Dr. McNamara performs a thorough evaluation before recommending decompression therapy to ensure it is safe and appropriate for your case.
