Inversion Tables for Neck Pain: Evidence, Risks and What Actually Has a Neck Feature

Does an Inversion Table Help Neck Pain? What the Research Says

Before judging the tool, it helps to know what it actually does to the spine, and what has been measured.

What an Inversion Table Actually Stretches

Inversion tables are a form of spinal traction. A 2023 paper in the journal Disability and Rehabilitation describes inversion table therapy as traction thought to relieve low back pain “due to the gravity-facilitated traction of the spine which distracts the lumbar vertebrae” (Kassay, 2023). Lumbar means the lower back. When you tip back and hang from your ankles, the weight of your upper body pulls on the spine below it, and the lower back is where that pull is described.

Two things follow. First, the mechanism is proposed, not proven: the authors write “is thought to,” and their paper is a regulatory and opinion piece, not a trial (Kassay, 2023). Second, it says nothing about the neck.

Your head is the lowest point when you invert, so there is very little body weight below the neck to pull on it. Whether a table stretches the cervical spine in any useful way has simply not been measured.

The Closest Evidence: Dedicated Neck Traction

The nearest thing to an answer comes from cervical traction, meaning devices built to pull on the neck alone. A systematic review and meta-analysis published in 2020 by Colombo and colleagues pooled seven randomized trials with 589 patients who had cervical radicular syndrome, a pinched nerve in the neck. Adding traction to other treatments reduced pain by about 6 points on a 0 to 100 scale compared with those other treatments alone (Colombo, 2020).

That difference was statistically significant, but only just. The authors had set 20 points as the smallest change that would matter to a patient, and traction did not come close. They rated the quality of the evidence as generally low, wrote that “none of these effects were clinically meaningful,” and concluded that traction “does not appear to be essential in clinical practice” (Colombo, 2020).

Keep the limits in view. Traction was always given together with other care, never on its own against nothing. And these patients had nerve symptoms, not the stiff, tense neck most people mean by neck pain.

What the Physical Therapy Guideline Recommends

The clinical practice guideline for physical therapists treating neck pain, the 2017 revision by Blanpied and colleagues for the American Physical Therapy Association, published in the Journal of Orthopaedic & Sports Physical Therapy, lands in a similar place. It gives a Grade B recommendation, meaning moderate evidence, for “mechanical intermittent cervical traction, combined with other interventions such as stretching and strengthening exercise plus cervical and thoracic mobilization/manipulation” (Blanpied, 2017). Three conditions are built into that sentence, and each one narrows it.

• Only chronic neck pain with radiating pain. The recommendation covers pain that travels into the arm and has lasted, not the everyday stiff or sore neck.
• Only in combination. Traction is one part of a program with exercise and hands-on treatment, never a stand-alone fix.
• Only intermittent. For continuous traction, the guideline found “no benefit, when compared to a control,” for pain or disability, in acute or chronic cases (Blanpied, 2017).

The same guideline also reports that traction should not be routinely prescribed as part of nonsurgical care for moderate to severe cervical myelopathy, a compression of the spinal cord itself (Blanpied, 2017). And across its 83 pages it does not mention inversion at all. A cervical traction device is a dedicated unit that pulls the head away from the shoulders, and in the intermittent form the guideline backs, it pulls and releases in cycles. An inversion table is a different machine: it hangs your whole body from your ankles and holds you there.

No Trial Has Used an Inversion Table

In the Colombo review, mechanical traction was used in six of the eight comparisons and manual traction, applied by a therapist, in the other two (Colombo, 2020). We searched the full text for “invert” and “inversion” and found neither word. No trial in that review used an inversion table.

This is an absence, so be precise about what it means. It does not prove an inversion table fails for the neck. It means nobody has tested one, and the devices that were tested apply force differently: a harness or unit pulls the head away from the shoulders, while a table hangs the whole body from the ankles.

A Weak Record in the Lower Back Too

Traction has not done better where an inversion table’s pull is actually described. A Cochrane review of 32 trials with 2,762 people found that traction, alone or with other treatment, made little or no difference to pain, function or return to work in low back pain (Wegner, 2013). That covers traction in general, not inversion alone, but it is the same family of treatment, in the region it targets.

Neck Pain or a Pinched Nerve?

This page covers general neck pain: stiffness, muscle tension, soreness that stays in the neck and shoulders. If your pain shoots down an arm, or comes with tingling, numbness or weakness in the hand, that pattern points to a compressed nerve root, which has its own evidence and its own page: can an inversion table help a pinched nerve. Those symptoms are also a reason to see a doctor before trying any traction at home.

Pressure in the Head: Blood Pressure, Eyes and Brain

The second set of risks sits right above the neck. Turning upside down sends pressure toward the head, and three studies have measured it.

Blood Pressure Goes Up

In a small randomized study of 60 healthy women aged 20 to 30, two minutes of inversion raised both systolic and diastolic blood pressure significantly compared with standing controls. The authors wrote that hypertensive individuals “may need to avoid its use” (Haskvitz, 1986). The abstract doesn’t give the rise in mmHg, and the sample was young and healthy, so an older adult with a stiff neck is not the group that was measured.

Eye Pressure Roughly Doubles

After five minutes fully inverted, eye pressure rose from 16.8 to 32.9 mmHg in healthy eyes and from 21.3 to 37.6 mmHg in eyes with glaucoma. The authors recommended that patients with ocular hypertension or glaucoma “refrain from this activity” (Weinreb, 1984). They also reported that visual fields did not change afterward, so the concern is the temporary spike, not measured damage.

Blood Flow to the Brain Changes

A 2019 ultrasound study on an actual inversion table found significant changes in a marker of intracranial pressure and in blood flow through the carotid and middle cerebral arteries after three minutes of inversion. The authors concluded that “inversion therapy should be used with caution,” especially for anyone with a history of raised intracranial pressure (Kondrashova, 2019). The published abstract gives no absolute values, so we don’t quote any.

None of this proves harm in a healthy user. It does explain why people who get tension headaches, or who already feel pressure behind the eyes, should not treat head-down time as a relaxation tool without asking a doctor.

Who Should Check With a Doctor First

Both major brands tell you not to invert without a physician’s approval. Teeter’s list includes high blood pressure, glaucoma, retinal detachment, osteoporosis, fractures, a history of stroke and severe headaches, among others (Teeter). Innova’s manual lists 21 conditions and adds some Teeter doesn’t name, including spinal injury and weak ankles and/or feet (Innova).

Spinal injury and weak ankles both matter directly to a neck: one describes the region at risk, the other the part that gives way in a fall. The full picture is in our guide to who should not use an inversion table.

Using an Inversion Table More Safely When Your Neck Hurts

If you and your doctor decide a trial is reasonable, these precautions come from the people who treated the injuries and from the manufacturers themselves.

Short Sessions and a Soft Landing

The authors of the 2021 case reports recommend keeping sessions under one minute and placing an angled pillow or rubber ramp just below the head, “allowing the user to slide to the floor rather than fall directly on their head.” They add that older or heavier users with weaker ankle strength should take extra care (Jung, 2021). That is their recommendation, not a clinical consensus, but it is aimed squarely at protecting the neck.

A Spotter and a Low Start

Innova’s FAQ tells users to start at a low inversion position, to invert slowly by raising one arm and then the other, to have a friend or family member present, and to return to horizontal before coming back up (Innova). For someone with neck pain, the spotter matters most: a person in the room can help you back up if your ankles slip.
