Cervical traction is a treatment that gently stretches your neck to create space between the vertebrae in your spine. By pulling the head away from the neck, it widens the small openings where nerves exit the spinal column, relieving pressure that causes pain, numbness, or tingling in the neck, shoulders, and arms. It’s used for a range of neck problems, from pinched nerves and herniated discs to degenerative conditions like arthritis of the spine.
How Cervical Traction Works
Your cervical spine (the neck portion) consists of seven vertebrae stacked on top of each other, separated by spongy discs and connected by small joints called facet joints. Nerves branch out from the spinal cord through narrow gaps between these vertebrae. When a disc bulges, bone spurs develop, or joints become inflamed, those gaps shrink and squeeze the nerves passing through them.
Traction applies a controlled pulling force along the length of the spine. This separates the facet joints and widens the openings (called foramina) where nerves exit. That separation takes direct pressure off compressed nerve roots, which is why people with radiating arm pain or numbness often notice the most dramatic relief. The stretching also helps relax tight muscles along the neck and upper back that may be contributing to pain and stiffness.
Conditions It Treats
Cervical traction is used for both acute injuries and chronic degenerative conditions. The most common reasons it’s prescribed include:
- Radiculopathy (pinched nerves) causing pain, numbness, or weakness radiating into the arm or hand
- Herniated or bulging discs pressing on nearby nerve roots
- Cervical spondylosis, the general wear-and-tear arthritis of the neck that develops with age
- Spinal stenosis, a narrowing of the spinal canal
- Degenerative disc disease, where discs lose height and cushioning over time
- Neck sprains and muscle tightness
- Scoliosis affecting the cervical region
Types of Cervical Traction
Manual Traction
A physical therapist or chiropractor uses their hands to pull your head gently away from your neck while you lie on your back. The therapist can adjust the angle and force in real time based on how your muscles respond. A typical session involves repeated pulls of about 10 seconds with 5-second rest periods, usually with the neck positioned at roughly 25 degrees of flexion (a slight forward tilt). The advantage is precision and responsiveness. The drawback is that the force naturally fluctuates because no human can maintain perfectly uniform pressure throughout a session.
Mechanical Traction
This uses a motorized or manually adjusted machine to deliver the pulling force while you lie on a treatment table. A harness fits around your chin and the base of your skull. The machine applies a consistent, measurable amount of force, typically set at 10 to 15 percent of your body weight. For someone weighing 160 pounds, that translates to roughly 16 to 24 pounds of pull. Sessions commonly last around 10 minutes, alternating between periods of pull and rest. Because the machine doesn’t fatigue, the force stays uniform, which some clinicians prefer for reproducibility.
Home Traction Devices
Several over-the-counter devices let you perform traction at home. The most traditional is an over-the-door unit: a pulley system that hangs from the top of a door frame, with a chin-and-head harness connected to a weighted bag. You sit in a chair, attach the harness, and add weight gradually. Inflatable cervical collars are another option; they wrap around your neck and expand as you pump air into them, applying a mild upward stretch. Foam or contoured wedge devices position your neck over a curved surface to create a passive stretch using gravity.
A retrospective study of 58 patients using a simple over-the-door home traction setup for just 3 to 5 minutes twice daily found that 81% experienced symptomatic relief from mild to moderately severe neck problems. That’s a meaningful result for such a low-cost, low-time-commitment approach, though results vary depending on the severity of the underlying condition.
What a Session Feels Like
If you’re getting mechanical or manual traction in a clinic, you’ll lie face-up on a padded table. The therapist places a harness or cradle around your head, positioning your neck at the appropriate angle for your specific condition. When the force is applied, you feel a gentle, steady pulling sensation along the back of your neck. It should not be painful. Most people describe it as a deep stretch, sometimes accompanied by a feeling of pressure release.
Sessions typically alternate between periods of active pull (around 10 seconds) and brief rest (around 5 seconds), though some protocols use sustained holds of several minutes instead. A full session usually lasts 10 to 20 minutes. You may feel looser and less achy immediately afterward, though some mild soreness in the neck muscles is normal for the first few sessions as your body adjusts to the stretching.
How Effective Is Cervical Traction?
Cervical traction reliably reduces symptoms for many people, but the research paints a nuanced picture. It works best when combined with other treatments rather than used alone. A systematic review and meta-analysis comparing traction to hands-on spinal manipulation for cervical radiculopathy found that manipulation produced better short-term results for pain scores, neck discomfort, arm numbness, and overall functional improvement. That doesn’t mean traction is ineffective. It means traction tends to work best as one piece of a broader treatment plan that includes exercise, manual therapy, and postural correction.
The combination of traction with mobilization and therapeutic exercise consistently outperforms traction as a standalone treatment across clinical studies. If your provider recommends traction, expect it to be paired with strengthening exercises for the deep neck muscles, stretching, and possibly hands-on joint mobilization.
Who Should Avoid It
Cervical traction is not appropriate for everyone. Conditions that make the spine structurally unstable can turn traction from helpful to dangerous. People with certain types of spinal fractures, severe osteoporosis, spinal cord compression, infections of the spine, or tumors affecting the vertebrae should not undergo traction. Rheumatoid arthritis that has weakened the ligaments at the top of the spine (particularly the joint between the first and second vertebrae) is another concern, because traction could allow excessive movement in an already unstable area.
Vascular conditions affecting the arteries that run through the neck also warrant caution. If you have a history of vertebral artery problems or significant cardiovascular disease, traction may not be safe. Pregnancy and acute inflammatory conditions of the neck are additional reasons providers may choose a different approach. Before starting traction, your provider will typically review imaging (X-rays or MRI) to rule out any structural issues that could make the treatment risky.
Home Traction: What to Know
If you’re considering a home device, start with guidance from a physical therapist or other provider who can recommend the right type of device, appropriate force level, and correct positioning for your condition. The angle of your neck matters. Too little flexion may target the wrong spinal segments, while too much can strain muscles or compress structures you’re trying to decompress.
Begin with very light force and short sessions (3 to 5 minutes), increasing gradually over days or weeks. Stop immediately if you experience sharp pain, dizziness, numbness that worsens, or headaches during or after use. Mild muscle soreness is expected early on, but anything beyond that warrants a conversation with your provider. Over-the-door units are inexpensive (often under $30) and have the longest track record of home use, but they require you to sit upright, which some people find less comfortable than lying-down options.
