Web•Peripheral nerves (motor and sensory) are stimulated with a controlled electrical stimulus and the response (distal nerve action potential) is recorded •Recorded responses include: •Compound motor action potential (CMAP) •Sensory nerve action potential (SNAP) •F-wave •H-reflex recorded responses •Compound motor action potential (CMAP) WebThe evoked response obtained from the electrical stimulation is called the compound motor action potential (CMAP) (Figures 2–2 and 2–3). By measuring the distance between the two stimulating sites and the difference between latency onset of the resultant CMAPs, the examiner can calculate the motor conduction velocity of that nerve segment. + +
