Chiropractor at Duluth Injury & Rehab Center in Duluth, Georgia utilizes MYOVISION sEMG scanning for better patient evaluation.

MyoVision’s ScanVision tool is an electronic form of palpation, which measures the muscular compensation for subluxations in the spine. This tool uses the same technology as an EKG which is used to measure electrical activtey in the heart. This device uses two small hand held scanners that are placed against the left and right side of the spine to measure muscular compensation for subluxation or issues with the spine. ScanVision scanning sEMG provides an objective means of measuring muscle activity about the spine, just as a cardiologist utilizes an EKG.

The benefits of this test is that it is painless, quick. and most importantly, it helps us determine what further evaluations or tests may or may not be necessary!

What do the Results of my sEMG Scan Mean?

Originally developed for use by NASA to measure the effects of zero gravity and fatigue on their astronauts it has recently been shown to correlate with neurological reflexes that occur with injury. For our purposes, we are concerned with dysfunction of the spine either due to injury, abnormal postures and other stress.

Colors indicate level of tension, with yellow, green, pink and red corresponding with very low, average, moderately high, and high 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 (yellow) are commonly seen when muscles are in a chronic state of fatigue from being overly stressed.

The test measures the amount of muscle activity (or inactivity) going on within a particular group of muscles surrounding the spine. If problems are long standing, abnormal muscle fatigue will be present; on the other hand, acute injuries will show up as abnormally strong, denoting overworking or spastic muscles. Spasms typically occur when the muscle has to protect a weakened joint and/or nerve. This is due to the laxity (stretching) that occurs in the damaged ligaments that hold the spine in place. These abnormal patterns in muscle activity can give solid evidence that there may be nerve irritation and subluxations in those areas of muscle dysfunction.

​Once the scan is complete the computer displays the data in a graphical format that is easy to understand for the patient. Interpretation relies on combining the information about both portions of the scan in conjunction with the other tests your doctor performed. This Myovision EMG provides your Chiropractor with objective readings of how the muscles surrounding the spinal segments are working and their imbalances. Using this enable your doctor to provide a more efficient evaluation of your spinal health and the best treatment to properly return the spine and surrounding muscles to proper health; it allows us to correctly outline a customized treatment plan just for you. More importantly, the doctors perform an updated scan after the completion of the initial phase of treatment, in order to analyze how your care has progressed and how the next phase of treatment goals should be tailored to correctly rehabilitate the spine, either through continued chiropractic treatment or through the referral/co-treatment of rehabilitation.

If you have any questions about interpretation of your scan or if you are not currently a practice member and would like to schedule an appointment with Dr. Joseph Hans for a complete evaluation please contact the office at (770) 622-9355.
