DMX is motion-based video X-ray that shows how spinal segments move in real time. It can document instability patterns translation (sliding) and angulation (tilting) that static MRI/X-ray can’t capture, helping guide stabilization-focused care.
- DMX evaluates function in motion, not just structure at rest.
- Translation and angulation are key stability metrics.
- Best used when symptoms are movement-triggered or trauma-related.

Patients and referring doctors often ask the same thing:
“What does DMX actually show that regular imaging doesn’t?”
At DMX Miami, we serve patients from Miami, Fort Lauderdale, Miami-Dade, Broward, the Florida Keys, and visitors traveling from the USA, Colombia, Chile, Argentina, Mexico, and the Caribbean. Many have already had MRI or standard X-rays but still have symptoms that are clearly movement-triggered.
DMX in One Sentence
DMX is fluoroscopic video X-ray that records spinal motion so providers can evaluate stability during real movement arcs.
What DMX Measures (Simple)
Translation = sliding
How much one vertebra shifts relative to another during motion.
Angulation = tilting
How much one vertebra tilts relative to another during motion.
These patterns help identify hinge segments and asymmetry that can correlate with symptom triggers.
When DMX Is Most Helpful
- whiplash / falls / sports impacts.
- symptoms triggered by turning, looking up/down, bending, or transitions.
- persistent symptoms despite “normal” static imaging.
- suspected instability affecting treatment decisions.
How DMX Improves Decision-Making
DMX findings can guide:
- stabilization-first rehab.
- safer manual technique selection.
- clearer documentation when needed.
- targeted progression based on motion behavior.
FAQs
Is DMX the same as MRI?
No. MRI shows structure; DMX shows motion function.
What does translation mean?
Translation is sliding motion between vertebrae.
What does angulation mean?
Angulation is tilting motion between vertebrae.
Does DMX replace other imaging?
No. It complements MRI/CT/X-ray when motion behavior is the key clinical question.
