Assessment of the peripheral, central, and autonomic nervous system function in styrene workers

11 styrene-exposed workers and age- and sex-matched healthy adult controls without cardiovascular, neurologic, or other potentially confounding disorders

Styrene exposure (estimated exposure of 22 ppm in air)

Age- and sex-matched healthy controls without styrene exposure

Peripheral, central, and autonomic nervous system functions measured by distribution of nerve conduction velocities (DCV), short-latency somatosensory evoked potentials (SSEP), variability in electrocardiographic R-R interval (CVRR), and sensory and motor median nerve conduction velocities (SCV and MCV)surrogate
