Why are two stimulation sites required to perform a motor nerve conduction velocity study?
What will be an ideal response?
To evaluate the motor nerves and eliminate the influence of conduction into the terminal branches and neuromuscular junction, two evoked potentials must be obtained, one proximal and one distal. The difference between the two latencies can be divided into the distance between the two stimulating sites in order to evaluate conduction within the motor nerve only.
