NCS-PARAMETERS

1. Onset latency: is the time required for an electrical stimulus to initiate an evoked potential. This reflects the conduction along the fastest fibers.

2. Peak latency: represents the latency along the majority of the axons and is measured at the peak of the waveform amplitude.

3. Amplitude: represents the size (number of axons participating) of the response, measured from baseline to peak or from peak to peak, depending upon how the reference data were collected.

4. Conduction velocity (CV): distance between the stimulation and recording electrodes divided by the onset latency.
