Motor Conduction Latency



- See: Sensory latency

- Discussion:
    - distal motor latency is the interval between the stimulus and the onset of the compound muscle action
            potential (CMAP) in the thenar muscles;
    - a motor conduction latency of more than 4.0 msec is significant;
    - incremental change of 0.4 msec in the palmar serial sensory study w/ use of measurements
            made at standard distances;
