Title Combined electroneurographic and electromyographic studies in lead workers
Bibliographic information 1995, Vol.52, p.415-419. 27 ref.
Abstract In order to evaluate the effects of chronic exposure to lead on the peripheral nervous system, nerve conduction velocity and electromyographic studies were performed on 31 lead workers of a battery recycling factory and 31 matched controls. Compared with the control group, the distal motor latency of the median nerve was significantly prolonged in workers with lead neuropathy. The electromyographic abnormalities found were neurogenic polyphasic waves in workers with abnormal electromyographic findings. There was a positive linear correlation between the index of cumulative exposure to lead and the distal motor latencies of the tibial nerve, as well as a negative correlation with conduction velocities of the sural nerve after multivariate analysis and control of potential confounding by age and sex. Electromyographic abnormalities also occurred in workers with blood lead concentrations between 17.4 and 58µg/dL. Electromyographic study in distal extensors of the upper limbs may be used as a tool for biological monitoring of effects in lead workers.
