Abstract

The Parameters of nerve conduction study, which are affected by low temperature, could be corrected by correction factor. The effect of temperature on various parameters was investigated and the correction factors for maximum and minimum conduction velocity were measured, The latency and duration of compound muscle action potential and sensory action potential have a linear relationship with temperature. The correction factors for maximum conduction velocity of motor and sensory nerves were 1.48 m/sec/oC, 1.56m/sec/oC, respectively and have a non-lineal relationship with temperature. The correction factors for minimum conduction velocity of motor and sensory nerver were 0.87 m/sec/oC 0.64m/sec/oC, respectively and have a linear relationship with temperature. The correction factor of maximum conduction velocity. is larger than that of minimum conduction velocity, which suggest that the large myelinated fibers are more sensitive to temperature change.

Key Words: Correction factor, Maximal conduction velocity, Minimum conduction velocity, Temperature
