Most neck pain doesn’t start with a single injury. It builds over years. Phone habits. Desk posture. Sleeping wrong. Symptoms show up. The cervical curve damage is usually already there. The Denneroll cervical orthotic is a targeted tool for correcting that kind of structural loss. Not in the office. At home, between visits, on your own schedule. Here’s how we use it at Glendale Chiropractic.
What the Denneroll Is — and Why It Exists
Your cervical spine has a C-shaped curve. Cervical lordosis. It’s there for a reason: shock absorption, weight distribution, space for the nerve roots to exit. Lose that curve and the system adapts. Not in a good way. Discs take on pressure they weren’t built for. Muscles pick up the slack. Nerve roots get crowded. The Denneroll is a passive cervical orthotic. Foam device, precisely shaped. You position it under the neck on a firm surface and lie back. That’s the whole setup. The shape applies gentle extension traction to the ligaments and soft tissues. Daily. Consistent. The curve responds over time.
What Causes the Neck to Lose Its Curve
The most common cause is sustained forward head posture. Looking down at a phone or tablet for hours a day. Working at a screen that’s too low. That repeated forward load gradually weakens the muscles supporting the curve, and over time, the curve flattens. In more advanced cases it reverses entirely, a condition called cervical kyphosis or straight neck syndrome. Whiplash does it differently. A car accident or sports impact can stretch or damage cervical ligaments in a single moment. Disc degeneration does it slowly. Vertebral height drops, the curve geometry shifts. Chronic neck pain and cervical stiffness that won’t clear with adjustments alone is often the signal. The structure needs attention.
Does the Denneroll Actually Work
Upfront answer: yes, for the right candidates. Research into cervical curve restoration using passive extension orthotics shows meaningful improvement in cervical lordosis angle, measurable reduction in forward head translation, and consistent improvements in chronic neck pain, tension headaches, and related symptoms. Not a single-session fix. Works through daily use over months. Patients who are properly fitted and follow the home protocol see real, lasting improvement. Not universal. Not instant. But the mechanism is sound.
Who Is a Good Candidate — and Who Should Skip It
Good candidates have measurable cervical lordosis loss on X-ray. Chronic neck pain, tension headaches, or radiating symptoms that haven’t cleared with adjustments. Forward head posture that’s run ahead of what the spine can self-correct. That said, not everyone fits. Hard contraindications:
- Severe osteoporosis
- Spinal instability or vertebral fractures
- Active infection or tumors in the cervical region
- Rheumatoid arthritis affecting the upper cervical spine
- Recent neck surgery or prior cervical fusion
- Certain vascular conditions affecting the neck
That’s a meaningful list. It’s why proper evaluation comes before the device. The Denneroll is not available over the counter for a reason.
The Glendale Approach — X-Ray Review, Then a Custom Fit
Dr. Brockway starts with your cervical imaging. The X-rays show the degree of curve loss, the direction of correction needed, and which size and placement of the orthotic will work for your specific spine. No guessing involved. Once candidacy is confirmed, we fit the device in the office. That means proper placement, a comfort check, and a walkthrough of the home protocol before you leave. The fitting appointment doesn’t take long. From there, the correction work happens at home. Daily, on your schedule, without requiring an additional office visit just to lie on an orthotic. Less time in the office means more consistent daily application, and consistency is what drives structural change.

Using Your Denneroll at Home
Start short. Two to three minutes daily. Build toward ten to fifteen as comfort improves, but don’t rush it. Firm surface only. Carpet or yoga mat. Never a bed. Device goes under the neck’s natural curve, sloped edge toward your feet. Head drops back. Relax into it. First week: some muscle pressure or soreness is normal. A neck that’s been compensating for years needs time to adjust. Sharp pain, dizziness, numbness into the arms, headaches that spike during or after a session: stop and call the office. Consistency matters more than duration. Ten minutes daily beats twenty minutes three times a week. Every time. Daily use, gradually increased, is what moves the needle.
The Full Cervical Protocol — Denneroll, Pro-Lordosis Exerciser, and Posture Halo
In many cases, Dr. Brockway pairs the Denneroll with two additional tools for patients who want to maximize their results at home. The Pro-Lordosis Exerciser from Ideal Spine adds an active component to the protocol, reinforcing the curve correction through targeted cervical extension movement rather than passive traction alone. The Posture Halo from Halo Posture supports upper cervical alignment and postural habits throughout the day. Together the three tools work from multiple directions. Passive structural traction, active muscular reinforcement, and sustained postural support. For patients whose main concern is broader posture rather than cervical curve, we run a separate dedicated posture correction program.
How Long Does Cervical Curve Correction Take
Realistic range: months, not weeks. Early wins come sooner. Less tension, fewer headaches, better range of motion. Those often show up within the first several weeks of consistent use. Structural changes to the curve itself take longer. Three to twelve months, depending on severity of loss, age, ligament flexibility, and how consistently the protocol gets followed. Mild flattening corrects faster than a full cervical kyphosis. Cause matters too. Posture-driven loss is more correctable than degeneration. Prior surgery changes the math. Dr. Brockway tracks progress with follow-up imaging and adjusts from there. Goal is lasting correction. Not symptom management while you’re still in care.
Ready to Find Out If You’re a Candidate
Straight neck. Forward head posture. Loss of cervical curve. Neck pain and headaches that haven’t fully cleared with adjustments. Any of those is a reason to ask whether the Denneroll makes sense for your spine. Dr. Brockway reviews your imaging, confirms candidacy, and gives you a straight answer. Patients with significant curve loss may also be candidates for our cervical correction program, which takes the structural work further.
