Failed physical therapy for neck pain? – You followed the plan:
- You did your stretches
- You stuck to the exercises
- You showed up for every physical therapy appointment
But your neck pain is still there or even worse.
If you’ve had little to no improvement with PT, it might not be your effort that’s the problem. The real issue could be a misdiagnosed or undetected ligament instability in your cervical spine.
At DMX Miami, we use Digital Motion X-Ray (DMX) to uncover hidden causes of chronic neck pain that physical therapy can’t fix because the problem was never properly identified in the first place.
Why Physical Therapy Sometimes Fails
Physical therapy works when the spine is stable and the diagnosis is accurate.
But if your pain is coming from ligamentous instability, traditional rehab strategies may actually make things worse.
Here’s why:
- Stretched or torn ligaments can’t stabilize the spine
- Strengthening muscles won’t correct joint instability
- Stretching or manipulation may cause more misalignment
- Pain persists because the mechanical source is still active
Until the true cause ligament laxity and vertebral motion during movement is addressed, therapy can feel like chasing your tail.
DMX: The Diagnostic Tool PT Can’t Offer
Digital Motion X-Ray (DMX) is a real-time imaging study that shows your neck while it moves.
It captures 30 X-ray frames per second during guided movements to reveal:
- Instability between vertebrae
- Alar and transverse ligament damage
- Subluxations or abnormal joint tracking
- C0–C1–C2 instability (common post-trauma)
DMX provides the missing piece that MRI and CT scans can’t offer motion.
That’s often when your symptoms appear, and exactly what PT can’t detect.
Who Needs DMX After Failed Physical Therapy?
You may benefit from a DMX scan if:
- You’ve completed PT but still have neck pain
- You feel worse after exercises or adjustments
- Your symptoms worsen with motion or posture
- You’ve had a concussion, whiplash, or head/neck trauma
- You’ve been told your MRI or X-ray is “normal,” but you know something’s wrong
DMX helps confirm whether instability is the reason PT didn’t work so you can stop wasting time and start healing.
