DynaROM Motion EMG

DynaROM testingWhat is DynaROM testing?
DynaROM testing is an incredible technology used to test for pain as a result of a work injury or soft tissue injury from an auto accident. The test is performed in the office and takes approximately 15 minutes to complete a full cervical and lumbar exam. Several sensors are placed on the body to measure both how far you can bend, and your muscle guarding response. You are asked to perform various motions as the sensors graph these measures. This data is vital in establishing the need for care and tracking your progress over time. It also serves as a great visual tool to help patients understand their current spinal condition.

What is Surface EMG testing?
Surface EMG testingSurface EMG testing uses technology similar to an EKG that is used to test the heart. The EKG measures heart muscle patterns and the Surface EMG measures the muscle activity of the spine. The exam only takes a few minutes and is absolutely pain-free. The test is non-invasive and safe for children, pregnant women and seniors. It simply requires the placement of small electrodes against the skin.

Why is testing muscle activity important?
When pain and spinal subluxation is present, muscles compensate by tensing up to brace and guard. The Surface EMG test will document the pattern of muscular guarding objectively and further establish the need for care. After an episode of chiropractic treatment, testing is repeated to track progress over time.

What do the results of the test mean?
Results are indicated by different colors along the spinal column. Colors indicate level of tension, with green, pink, red and yellow corresponding with average, moderately high, high and very low readings respectively. Percent difference displayed is the difference between left and right sides at the level measured, with arrows pointing the direction of imbalance. Both very high (red) and very low (yellow) readings are significant. High readings (red) are typically seen in the acute phase of spinal subluxation or injury, while very low readings (yellow) are commonly seen when muscles are in a chronic state of fatigue.

How does this relate to your health?
Just as blood pressure cuff is used to track your cardiovascular health, the MyoVision Surface EMG is used to track your spinal health. The data helps determine the proper course of care and track your progress over time with an easy to understand visual tool.

What is the EP Stress Score?
The Electrophysiological (EP) Stress Score is calculated by adding up all muscle activity readings for both left and right sides at all levels of the spine. This sum of all muscle activity about the spine provides a baseline measurement for which all subsequent readings are compared. This allows us to track your progress over time with a simple single number. This number means very little on its own. The first reading is used to create a baseline. All subsequent readings are compared with the baseline for the purpose of tracking progress.

​Elevated EP Stress Score readings on a first exam are associated with the acute state of subluxation and/or spinal health. Readings typically will drop after 4-6 weeks of care. Low EP Stress Score readings on a first exam are associated with a chronic problem, with muscles in a state of fatigue. Expect your EP Stress Score to increase, as muscles begin to fire more normally. Since no one lives static lives, expect your EP Stress Score to reflect your activities of daily living – scores will differ if you are more or less active between scans. Everything from sitting at the computer too long to playing sports will impact your score.
