Calculated nerve conduction velocity dependence upon the method of testing.
Nerve conduction velocities using the evoked nerve potential can be calculated using six different methods. The latency may be measured to the onset of the negative potential or to the negative peak, using techniques of single or dual stimulation and single or dual recordings. Each method produces a value that is dependent on the method used for latency measurement and velocity calculation. The major factor producing the variability is the measurement of latency to the negative peak of the evoked potential. Awareness of these calculation artifacts is necessary to set standards and compare values.
