The Insight sEMG technology is similar to the technology used in EKG/heart rate measurement machines. One primary difference is that the Insight sensors are 1,000 times more sensitive, since the paraspinal muscles generate less electrical activity [action potential] than the heart muscle. The sensitivity and accuracy of the Insight technology is unsurpassed!

One of the most exciting technologies in contemporary chiropractic practice, sEMG measures baseline status and changes in the electrical activity of paraspinal muscles in order to quantify the muscular changes associated with vertebral subluxations. This makes it a powerful tool for tracking outcome assessment results from chiropractic care.


sEMG – Asymmetry Scan
This scan of a patient’s muscle asymmetry depicts the amount of muscle pull from one side to another. Normal is marked by white spikes or no spikes at all. The same colors are used here – green, blue and red for mild, moderate and severe levels of muscle asymmetry respectively.


sEMG – Pattern View
This graph is the Insight’s sEMG “pattern View”. This analysis is a unique, patent pending sEMG application that only the Insight provides. Of primary importance to the chiropractor is the way muscle energy is being distributed throughout the spine. Patterns can demonstrate ‘efficiency’ or they can exhibit lack thereof. Think of it sort of as the motor systems ‘miles per gallon’ rating. A person’s somatotype or age may affect sEMG amplitude signals. But with the Insight’s breakthrough pattern view, clinical impressions will not be skewed due to these factors. Colors and the shape of the lines serve as visual cues to easily assess the results.


sEMG – Amplitude Scan
The patient’s sEMG scan is compared to normal. We are viewing the amplitude (amount of tension) of paraspinal muscle activity, along with hyper- or hypo-tonicity as it compares to a normal population. Green bars indicate one standard deviation over normal, or mild elevation. Blue bars indicate moderate elevation and Red bars indicate severe elevation. Yellow indicates one standard deviation below normal.
