The conventional nerve conduction study measures only the maximal conduction velocity, which represents a minority of the fastest conducting fibers in the human peripheral neve. Therefore, it is unable to detect pathology of majority of nerve fibers with submaximal conduction velocities. We measured the maximal and minimal conduction velocities of ulnar and peroneal nerves on 2 adults, ages 19 to 68.
The maximal and minimal conduction velocity of ulnar nerve were 69.54⁑7.64 m/sec and 56.30⁑5.66 m/sec, respectively and these of the peroneal nerve were 53.55⁑4.70 m/sec and 44.33⁑3.88 m/sec, respectively. The differences of maximal and minimal conduction velocity were 13.21⁑4.40 m/sec in ulnar nerve, 9.21⁑2.84 m/sec in peroneal nerve.
