MyoVision DynaROM™ Motion sEMG

Vehicle Accident Testing

Introducing DynaROM

MyoVision’s DynaROM™ simultaneously measures muscle activity and Range of Motion – so we can finally 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.

What is DynaROM?

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, we effectively elicit measurable pain responses and guarding when soft tissue injury is present.

DynaROM is the latest in FDA cleared, class II diagnostic equipment. It effectively and objectively measures the impact of soft tissue injury by documenting pain in motion.

“The Lie Detector Test for Back Pain”

“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.” (

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