Digital Motion X-Ray
what is DIGITAL MOTION X-RAY (DMX)?
Digital Motion X-ray (DMX) is painless and often reveals permanent ligamentous injuries commonly missed by other diagnostic procedures. The areas most frequently studied are the cervical spine, facet joints, and the temporomandibular joints. Extremities, shoulders, back and primary elbow, wrist, knee and ankle joints are also easily visualized using DMX.
It is of primary importance in the care of the patient to establish the presence of ligamentous damage, as these ligaments do not heal. The movement of the articular surfaces results in pain via fibers of the nervous system. Long term degenerative damage results from connective tissue injuries. MRI, ultra-sound, traditional film x-rays and other diagnostic tools cannot diagnose connective tissue injuries; only DMX provides objective visual documentation of ligamentous injury.
Digital Motion X-ray studies are recorded on video as the patient moves the injured or affected area. In a 90 second cervical study, 2,700 real-time frames of evidence are recorded. Playback shows the patient both in x-ray image and in a “positive” image at the corner of the screen. Without seeing the patient move, doctors often cannot find the cause of their patient’s pain and fail to diagnose connective tissue injuries. Additionally, still images can be printed from any of the 2,700 images in a study.
DMX provides accurate, crystal-clear moving images to aid in diagnosing and treatments planning for:
Patients injured in vehicular crashes
Work related injuries / Worker’s Compensation Cases
Upper cervical spine injuries or degenerative diseases
Anterior or posterior listhesis
Facet gapping and/or gliding
Dislocation and chronic subluxation
Barium Swallow Studies
DO I NEED A DIGITAL MOTION X-RAY?
Who may need a dmx
Digital Motion X-ray is painless and often reveals permanent ligamentous injuries commonly missed by other diagnostic procedures. For example, diagnosis of whiplash injuries rely upon non-moving diagnostic procedures, such as static x-rays, stress view x-rays, CT, and MRI. During these tests, patients are asked to stand or lie still: “Don’t move ” and/or “Hold your breath.” Patients hurt more when they move, and pain is commonly an indicator of injury. The majority of these non-moving diagnostic tests come out negative or unremarkable.
It is important to know that there are two different types of ligament injuries. One is called a complete failure, or “tear,” and the other is a sub-failure, which is a stretching of the ligament. Loose ligaments can only be demonstrated through a motion imaging procedure. That is why DMX can reveal these sub-failure ligament injuries in as little as 15 minutes, allowing the doctor to specifically determine which ligaments are injured.
Signs and Symptoms of Injuries and Why you may need a DMX:
Neck or back pain
Numbness and Tingling
Other tests negative
Help show injuries in legal cases
Dizziness or Nausea
Loss of motion
Pain with motion
Continued pain after treatment

What is Digital Motion X-Ray?
Digital Motion X-Ray (DMX) is simply a new type of fluoro-based x-ray system, coupled with new digital and optic technology, allowing clinicians to view the spine in real-time motion at 30 x-rays per second. The procedure is performed with the patient standing and actively moving in a weight-bearing position within the system.
Doesn't Flexion Extension X-Rays show all ligamentous injuries?
We are taught in school that cervical flexion/extension x-rays were all we needed to rule out ligamentous injury. The truth is, these x-rays are taken during one arc of motion, at end points. This evaluates only 2 of the 22 major ligaments of the cervical spine. DMX allows us to evaluate all 22 major ligaments of the cervical spine with 2,700 x-ray images. The only two ligaments the flexion/extension x-rays may detect if patient positioning is proper, are the anterior and posterior longitudinal ligaments. The ligaments that are not diagnosed are the:
- Right and left alar ligaments
- Right and left accessory ligaments
- Transverse ligament
- Five right capsular ligaments
- Five left capsular ligaments
- Five interspinous ligaments
What is the difference between DMX and MRI?
DMX is simply a new type of x-ray system that allows the clinician to take x-rays while the patient moves in a standing weight-bearing position. DMX evaluates the bones in motion allowing us to detect which specific ligaments have been injured. If you hurt more when you move, then you must be diagnosed while you move.
MRI of the cervical spine is designed to evaluate disc injuries while not moving, lying down, and not swallowing. The symptoms of a cervical disc injury are usually numbness and tingling in the upper extremities. The upper 30% of the spine and posterior aspect of the spine contain no discs, just ligaments. Headaches and posterior neck pain are commonly caused by stretched ligament injuries which cannot be detected by MRI.
What is the radiation exposure?
The DMX system can produce 2,700 x-ray images with the same amount of radiation as a standard x-ray machine, which gives you 6 static x-rays.
Does insurance cover this type of procedure?
We follow a simple rule: If the insurance company reimburses you for static x-rays, there is no reason why they wouldn’t reimburse you for an x-ray that moves.
How does DMX help attorneys settle cases?
DMX provides “demonstrable” or “observable” evidence of the injury. This is the reason why insurers are fearful of this technology because it shows the injury.
How does Digital Motion X-Ray improve patient care?
It let’s you see the injury in ways you’ve never seen it before. Hidden injuries are revealed, helping you design a more effective treatment plan for your patient based on a more complete diagnosis.
