METHODS, SYSTEMS, AND DEVICES FOR DETERMINING AND VISUALLY INDICATING DEMYELINATED PATHWAYS

摘要

A method includes receiving multiple compound muscle action potential values (CMAPs), wherein each CMAP is an onset latency, a peak latency, a conduction velocity, or a response amplitude measured from a baseline; for each of the CMAPs and for each of a number parameters calculated from the CMAPs, determining a corresponding demyelinating boundary value using a normal value from a preselected population; determining whether each of the CMAPs and each of the parameters exceeds the corresponding demyelinating boundary value; determining one or more demyelinated nerve pathways based on which of the CMAPs and the parameters exceeds the corresponding demyelinating boundary value; indicating on a display which of the CMAPs and the parameters exceed the corresponding demyelinating boundary value; and displaying, in pictorial form, an anatomical diagram indicating the demyelinated nerve pathways.

1. A non-transitory computer-readable medium, having computer-executable instructions stored thereon, that in response to execution by a device, cause the device to perform operations comprising:
receive a plurality of compound muscle action potential values (CMAPs), wherein each CMAP is an onset latency, a peak latency, a conduction velocity, or a response amplitude measured from a baseline; for each of the plurality of CMAPs and for each of a plurality of parameters calculated from the plurality of CMAPs, determine a corresponding demyelinating boundary value using a normal value from a preselected population; determine whether each of the plurality of CMAPs and each of the plurality of parameters exceeds the corresponding demyelinating boundary value; determine one or more demyelinated nerve pathways based on which of the plurality of CMAPs and the plurality of parameters exceeds the corresponding demyelinating boundary value; indicate on a display which of the plurality of CMAPs and the plurality of parameters exceed the corresponding demyelinating boundary value; and display, in pictorial form, an anatomical diagram indicating the demyelinated nerve pathways.
