Electrodiagnostic testing is an integral part of the evaluation of the motor unit in many neurologic conditions. Literature about the peripheral nervous system of flying foxes (Pteropus spp) is sparse, and reference range values for motor nerve conduction velocities in vivo have not been established in Chiropterans. The goals of this study were to determine reference range conduction velocities in flying fox for the thoracic and pelvic limb nerve. Eight Pteropus vampyrus, large flying foxes, of varying ages and gender underwent nerve conduction studies of the median nerve and sciatic-tibial nerve. Mean (SD) conduction velocity values were 49.8 (12.7) m/sec for the median nerve and 42.1 (10.2) m/sec for the sciatic-tibial nerve. Median nerve conduction velocities were not significantly faster than sciatic-tibial nerve conduction velocities, although a trend was seen. Differences by sex or age class were not statistically significant. It was also noted that flying foxes rapidly lose body heat under general anesthesia.
