You can display Static EMG scan data as listed below.
|EMG Amplitude||Shows Static sEMG readings for each spinal level as a color-coded bar indicating amplitude and deviation from norms, superimposed on an illustration or photo.|
|Bar Graph||Shows Static sEMG readings for each spinal level as a simple color-coded bar graph. Bars indicate the amplitude in micro volts; bar color shows standard deviations from norms.|
|Normal Means Graphic||Shows normal sEMG readings for each spinal level as a white bar, superimposed on a spine or muscle illustration or photograph. Bars indicate the amplitude in micro volts.|
|Normal Means Bars||Shows normal sEMG readings for each spinal level as a simple white bar graph. Bars indicate the amplitude in micro volts.|
|Assymetry||Shows percentage differences in sEMG readings between right and left levels as triangles; the triangle marks the higher side. Colors show standard deviations from norms.|
|Table||Shows all statistics for each spinal level, including the Neurocalorimetric (NCM) (left/right differential) value, expected NCM norm and standard deviations, and absolute temperatures.|
|Pattern View||Details below.|
When you click on the “View” icon after saving an EMG scan, myINSiGHT™ launches your browser and displays both the Static EMG Amplitude View and the Pattern View.
The Pattern View shows scan data in a holistic manner that compares the patient’s muscle energy distribution pattern to a normal distribution pattern. The focus is not on a segmental breakdown by spinal level, but on the whole spine.
In the pattern views, the white sections that create a “pear” shape represent the normal patterns for muscle energy distribution, and the heavy black lines show the patient’s pattern. In a perfectly normal pattern, the heavy black lines would go down the middle of the white areas on each side of the pear, and would be a very smooth pear shape. It is very easy to see how the patient’s pattern contrasts with the normal pattern by looking at how well the black lines conform to the shape of the white areas – smoother, pear-shaped black lines show better patterns and jagged, spiky black lines show poorer patterns.
In these views, you can see certain places on the spine, such as the upper thoracic in the view on the bottom, where the patient’s data (black lines) are outside the pattern. In such cases, the colors in the “spike” outside the pattern indicate the severity of the deviation by showing the number of standard deviations outside the pattern. Deviations above the expected pattern are shown in green, blue, or red, and deviations below the pattern are shown in yellow. (The faint white lines outside the pear shape represent boundaries for each level of deviations, up to 4 deviations or more above the norms).
In addition to the very clear illustration of total energy distribution provided by the view, several statistic “scores” shown on the right aid further in interpretation.
- Pattern Score – Pattern is a cumulative score relative to a “perfect” pattern (a pattern that exactly matches the normal.) A perfect pattern has a score of 100%, and the goal is to increase the pattern score as the patient advances through care.
- Symmetry Score – Symmetry is a cumulative score that shows the presence or absence of left-right imbalances (asymmetries). A perfect score of 100% means a completely balanced spine with no asymmetries. As with the pattern score, the goal during care is to improve the symmetry score, and in this case the scores improved from 63.60 to 76.82.
- Total Energy Score – Total energy is a cumulative score representing the total amplitude of sEMG values. A score of 100 indicates that the sum of all the amplitudes in the each of the scanned levels equals that of the normative data. Scores of less than 100 indicate lower than normative total amplitude, and scores of greater than 100 indicate higher than normative total amplitude. In this case there has been a very slight increase in total energy, from 99.62 to 106.74.
