• We fixed a small defect where the left and right dermatomes, on the bottom, back portion of the dermatome diagram, were inverted. Because of this, the right dermatomes on the bottom, back portion of the diagram got highlighted when left values were entered, and vice versa.

• Updated to version 1.0.3
  A new NuGet package was published, containing the changes in version 1.0.2, to support both .Net framewors: 4.0 and 4.5. The package is available at the NuGet website for download.

• Updated to version 1.0.2
  We have fixed a minor issue where, in some special cases only, the algorithm was not comparing both left and right when determining if motor function was present more than three levels below the motor level on that side. This error was causing these cases, which should have been evaluated as AIS C, to be evaluated as UTD with options of AIS B and AIS C.

• We have done a minor release yesterday. Amongst some of the changes we have made are:

  • Fixed the spelling mistake in the totals box above the Zone of Partial Preservation.
  • Minor improvements to the interface which include the use of larger buttons and the dermatome man from the latest ISNCSCI form version.
  • Fix to the algorithm which was reporting an incorrect single neurological level when the left and right sensory levels were different from each other and higher than C5.
  • We have added a button to allow you to clear the form so you can begin a new entry.

  If you find that the form is displaying funny, press the refresh button on your browser to force it to download the latest styles. We hope you find these updates useful and keep using the web tool. We appreciate all the feedback we have been receiving and will continue to use it when planning our future releases. Please remain in touch.
