Have you ever walked out of a chiropractic appointment feeling worse not better?
Maybe you’ve tried spinal adjustments, physical therapy, or neck manipulations and experienced:
- Increased headaches
- More dizziness or nausea
- Tension, soreness, or brain fog
- Worsening neck pain with movement
If that’s happened to you, it’s time to ask:
“Could I have undiagnosed cervical instability?”
At DMX Miami, we help patients who don’t respond to traditional therapies uncover the real reason their neck won’t stabilize using Digital Motion X‑Ray (DMX) to detect ligament injuries missed by MRI or X-ray.
When Neck Adjustments Make You Worse
Chiropractic care and manual therapy are incredibly helpful for many people when the spine is stable.
But if your cervical ligaments are damaged, even small adjustments or stretches can:
- Trigger symptoms
- Cause excessive vertebral motion
- Increase brainstem pressure or nerve irritation
- Prolong recovery or worsen instability
This is especially true in the upper cervical spine (C0–C1–C2) where tiny movements can have a big neurological impact.
Why Ligament Instability Changes Everything
The ligaments in your neck act like guide wires, keeping the vertebrae aligned and protecting the spinal cord and brainstem.
When injured (from whiplash, concussion, trauma, or years of poor posture), those ligaments:
- Stretch or tear
- Allow abnormal bone movement
- Create mechanical stress during motion
- Lead to symptoms like dizziness, light sensitivity, head pressure, or brain fog
These subtle issues are almost never visible on MRI or static X-rays but they’re exactly what Digital Motion X-Ray is designed to reveal.
What Is DMX — and Why It Matters

Digital Motion X-Ray (DMX) is a real-time imaging test that records your cervical spine while you move your head through guided positions.
It captures:
- Excessive motion between vertebrae
- Laxity in the alar and transverse ligaments
- Instability at C1–C2 or the craniocervical junction
- Vertebral misalignment not visible when lying still
This allows us to see what your spine is doing during real-life motion not just in a resting position.
Not All “Instability” is the Same
You don’t have to have a broken bone or visible trauma to be unstable.
DMX is often the first and only test that shows:
- Why spinal adjustments aren’t helping
- Why PT or massage therapy worsens symptoms
- Why patients feel “off” despite normal scans
In some cases, we advise patients to avoid cervical manipulation altogether until their instability is corrected with rehab, regenerative therapy, or bracing.
