Abstract: The aim of this study was to investigate the effects of extremely low frequency (ELF) magnetic field on nerve conduction velocity, depolarization amplitude and latency. The nerve was exposed to extremely low frequency magnetic field by utilizing a special Helmholtz applicator. The experiments were carried out on a group of healthy volunteers. The group consisted of 20 persons, aged 30–52 years, 10 male and 10 female. This study two main states were conducted; pre-exposure group and post-exposure group. 4-channel NCS/EMG/EPS digital electromyography was used for the recording on latencies, depolarization amplitude and nerve conduction velocity from pre-exposure and post exposure group. The values of distal and proximal responses from median nerve were obtained as procedure. In this study demonstrated that affect power frequency with 50 Hz-1 mT magnetic field on human median nerve. 50 Hz-1 mT magnetic field should not be recognized as safe for conduction mechanism on a nerve.
