¹Normative values are listed in Table 2. Sensory studies are orthodromic except patient 7, who had an antidromic median sensory study.
²Amplitude values for sensory studies are microvolts and motor studies are millivolts.
^3,4 Conduction velocities and F-wave latencies were normal for all nerve studies.
