At Sunset Chiropractic & Wellness in Miami, we use Digital Motion X-Ray (DMX) to uncover spinal damage, ligament instability, and dysfunction that are often missed by traditional MRI, CT scans, or static X-rays.

One of the most important tests we perform is the open-mouth cervical DMX view. This specialized imaging allows us to visualize and measure the alignment between the skull (C0), the atlas (C1), and the axis (C2). This area—known as the upper cervical spine—is critical for whole-body neurological function and postural stability.

Unlike static imaging, DMX captures your spine in motion, providing real-time analysis of ligament integrity, biomechanics, and abnormal movement patterns. This is especially vital when evaluating cervical ligament instability, a condition where damaged ligaments allow excessive motion between vertebrae. This can result in spinal misalignment, neurological stress, and a wide range of symptoms—often with “normal” findings on MRI or CT.

Why the Upper Cervical Spine Matters

Injuries or instability here affect gravity distribution throughout the entire spine, contributing to widespread postural and neurological dysfunction.

DMX allows us to evaluate all 22 major ligaments of the cervical spine under motion and weight-bearing conditions. This technology can detect:

• Abnormal cervical motion
  
  
• Ligament laxity or tears
  
  
• Hidden spinal instability
  
  
• Post-traumatic injuries

The 22 major ligaments evaluated include:

The 22 major ligaments evaluated include:

• Posterior Longitudinal Ligament
  
  
• Anterior Longitudinal Ligament
  
  
• Right and Left Alar Ligaments
  
  
• Right and Left Accessory Ligaments
  
  
• Transverse Ligament
  
  
• Five Right Capsular Ligaments
  
  
• Five Left Capsular Ligaments
  
  

Five Interspinous Ligaments

If you’re suffering from chronic headaches, dizziness, neck pain, balance issues, or post-concussion symptoms and haven’t found answers, DMX may reveal the true source of your condition.

What is Digital Motion X-Ray?

Digital Motion X-Ray (DMX) is a real-time, dynamic imaging system that allows doctors to view the spine and joints while you move. It works by using fluoroscopy, a form of continuous X-ray that captures 2,700 images per minute as you perform natural movements. This motion-based analysis makes DMX far superior to traditional static X-rays, CT scans, or MRIs when it comes to evaluating instability, ligament injuries, and misalignments.

Because DMX records your body in action — not at rest — it provides critical insights into how your spine and joints behave under stress, load, or motion, revealing instabilities that only show up when the body is in use.

This is especially powerful when evaluating the upper cervical spine (C1/C2 area) — a region that houses vital neurological structures like the brainstem, vagus nerve, and vertebral arteries. Injuries here can affect both physical and autonomic functions, leading to a broad and often confusing range of symptoms.

Symptoms of Ligament Instability: What to Watch For

Ligament injuries, particularly those involving the neck or upper spine, can be difficult to diagnose. Over time, damaged ligaments lose their ability to stabilize joints, leading to abnormal motion, chronic stress on nerves, and impaired neurological function.

We divide the symptoms into two categories — neuromusculoskeletal and autonomic nervous system symptoms — to better help patients and clinicians recognize the patterns of instability.

Neuromusculoskeletal Symptoms

These symptoms are typically associated with joint dysfunction, spinal misalignment, and nerve interference:

● Chronic neck pain or stiffness that worsens with movement
 ● Clicking, popping, or grinding in the neck, jaw (TMJ), or shoulders
 ● Pain that increases with prolonged posture or physical activity
 ● Radiating discomfort or pain into the shoulders, upper back, or arms
 ● Muscle tightness, spasms, and chronic tension
 ● Numbness, tingling, or altered sensation in the arms or hands
 ● Difficulty with overhead movements or shoulder instability
 ● TMJ dysfunction including jaw pain, clenching, or difficulty chewing
 ● Headaches that originate from the neck or base of the skull
 ● Worsening of scoliosis or spine curvature-related symptoms

These are often dismissed or misdiagnosed — especially if traditional imaging comes back “normal.”

Autonomic Nervous System Symptoms

When instability affects the cervical spine, it can interfere with brainstem function and autonomic regulation. That’s why many people with ligament injuries also suffer from symptoms like:

● Dizziness, vertigo, or unsteadiness (especially when turning your head)
 ● Sudden fluctuations in blood pressure or heart rate
 ● Irregular heartbeat or palpitations
 ● Chronic brain fog or poor concentration
 ● Persistent fatigue not relieved by rest
 ● Anxiety-like symptoms without clear psychological cause
 ● Blurred vision, visual disturbances, or light sensitivity
 ● Feeling faint upon standing (orthostatic intolerance)
 ● Breathlessness or difficulty breathing normally
 ● Sensations of pressure behind the eyes, sinuses, or ears

These symptoms can mimic other conditions and are frequently misattributed to stress, aging, or general fatigue — when in fact, the root cause may be cervical ligament damage.

How DMX Helps You Get the Right Diagnosis

What makes DMX so valuable is its ability to reveal real-time movement and misalignment that conventional scans can’t detect. Here’s what makes it stand out:

● Captures 2,700 dynamic images per minute — showing true motion, not just still slices
 ● Evaluates ligament laxity, elongation, and instability in real time
 ● Identifies problems in the cervical spine, TMJ, and upper thoracic region
 ● Assesses movement during weight-bearing, flexion, extension, and rotation
 ● Offers unparalleled insight into chronic, undiagnosed symptoms
 ● Uses a radiation dose comparable to a typical X-ray — safe and efficient
 ● Helps correlate structural problems with both neuromusculoskeletal and autonomic symptoms

In short, DMX helps bridge the gap between symptoms and diagnosis — often revealing the “missing link” in complex cases.

DMX motion x-rays are analyzed with  Computerized Radiographic Mensuration Analysis (CRMA) to achieve accurate measures and to determine the extent of the injury and ligament damage.

Who Should Consider Digital Motion X-Ray?

You might benefit from a DMX scan if you’ve experienced any of the following:

● Car accidents or whiplash injuries, even minor ones
 ● Chronic neck pain, tension headaches, or migraines
 ● TMJ disorders or jaw clicking/popping
 ● Failed back surgery or unresolved pain after chiropractic care
 ● Dizziness, vertigo, or balance issues
 ● Sudden or unexplained blood pressure or heart rate changes
 ● Brain fog, fatigue, or neurologic symptoms without clear cause
 ● Post-concussion symptoms or head trauma
 ● Scoliosis or progressive postural changes
 ● Chronic pain that other doctors have not been able to explain

If your symptoms have persisted despite multiple evaluations, medications, or therapies, DMX may provide the breakthrough you need.
