Study on the Effect of Manganese on the Conduction Velocity of Peripheral Nerves

Objective] The aim was to study the effect of the manganese intoxication and exposure on the conduction velocity of peripheral nerves. [Methods] In 40 observed objects and patients of case group,and 48 persons of control group.the conduction velocity of peripheral nerves was examined by electromyography. [Results] The results showed that there is a significant difference in the peripheral conduction velocity in which the sensory conduction velocity is much slower and the distal latency is longer in case group ( P 0 01). [Conclusion] Manganese was harmful to not only central nerve system but also peripheral nerve system. The peripheral nerves conduction velocity can be used as a reference parameter for diagnosis of the chronic manganese intoxication.
