DynaROM Motion EMG is the latest in FDA cleared,  diagnostic equipment. This patented technology effectively and objectively measures the impact of soft tissue injury by documenting pain in motion. 

DynaROM, or Dynamic Range of Motion, is a functional test that measures muscle guarding and range of motion at the same time as the patient moves. By moving the patient, you effectively elicit measurable pain responses and guarding when soft tissue injury is present. ​​By measuring both at the same time, it increases the sensitivity and specificity of ROM measures by including the muscle guarding component.

What do the results mean?

In the graphs below you will see 2 measurements - Muscle Guarding (upper half of the graph) and Range of Motion (lower half of the graph). These measurements are happening simultaneously while your patient performs 3 repetitions of a motion over a time span of 30 seconds. There are six of these 30 second tests to measure flexion, extension, left and right lateral flexion and left and right rotation. 

Muscle guarding (top graph) is measured in Microvolts (the y-axis), across seconds (the x-axis). The blue line is the left lumbar, the red line is the right.  

Range of motion (lower graph) is of course measured in degrees, and not only shows the degree of motion, but also the "quality of motion." Instead of only seeing the end point (the peak in this graph), you can also see "how" the patient moved into that motion. If the patient ratchets in pain, the graph shows this.

DynaROM objectively show the issues they state subjectively (like saying "ow, that hurts"). 

You can see the patient has normal ROM (lower graph) yet when they are fully relaxed, their muscles are still firing (upper graph) clearly showing injury.

​The data gathered correlates highly with components of soft tissue injury by measuring the muscular compensation / response to muscular, ligamentous connective tissue and/or intervertebral disc soft tissue injury and spinal function.  By simultaneously measuring and graphing both the active ranges of motion and the muscle guarding response, a more sensitive measure, which correlates more highly with actual patient function, emerges. Unlike MRI, CT or ROM testing, DynaROM is performed in motion which elicits abnormal muscle function if present. ​In addition, it can expose both symptom magnifiers and malingerers by demonstrating lack of abnormal muscle function or guarding when seen concomitantly with abnormal ranges of motion.  

​Muscle guarding is the body‘s response to pain in motion and helps establish the validity of a patient’s subjective complaints of pain or lack thereof in a manner more accurate than traditional endpoint range of motion.

Eliminate the guess work.

The only functional test of its kind to provide the proper documentation necessary for Personal Injury practices.

• Document muscle firing activity and ROM at the beginning, middle and end of care
• Document progress/regression based on findings
• Determine proper treatment
• Evaluate both progress and effectiveness of chosen treatment
• Validate initial injury and permanent injury at MMI
• Expose symptom magnifiers and malingerers

This is an ideal exam showing normal ROM, no muscle guarding.

It's so validating

Its integrated use of sEMG and true wireless dual ROM is brilliant. Surface EMG effectively augments ROM by assessing effort.

This is a win/win situation for everybody... for the adjusters, the attorneys - you can weed out the patients that really don’t need the care, and you can continue the care for people who do need it. I was totally dumbfounded and noticed that they were allowing me to treat my patients - I wasn’t getting these letters from the insurance companies with IMEs. The only thing that I’ve changed was incorporate your program into this, nothing else.

Before purchasing, I did not believe the claims I had heard. Now after being paid in full for the first time in 30 years, I know the claims are true. Just two PI cases paid for my machine, but more importantly, it provides the objective data attorneys are looking for.

DynaROM vs. ROM

Do you have patients who show normal MRI & normal endpoint ROM, but you know they're in pain? 

Over the past several years, we have noticed a large number of patients who display abnormal muscle guarding via DynaROM, despite having a relatively normal range of motion. 

​MyoVision's DynaROM™ simultaneously measures muscle activity and Range of Motion, so we can see graphically, not only the "quality of motion," but if muscle guarding (a critical measure of patient's level of pain) occurs. This patented device allows us to objectively document a patient's response to soft tissue injury. Negative IME? No problem. DynaROM removes opinion from the argument and puts you in charge of patient care.​

Watch this short video to learn why DynaROM is the tool of choice for establishing the presence or absence of soft tissue injury.

DynaROM has revolutionized the entire process of quantifying soft tissue injury by keeping adjusters, doctors and juries focused on the quality of data.

The DynaROM's validity has been established all the way up the Supreme Court level. Its precedence is widely known and growing every day. With the DynaROM, you have the data and the documentation necessary to establish need for care.
