Conclusion (acc. to author)

No association was observed between specific psychosocial work characteristics nor personal traits and hypersensitivity to electricity. Skin symptoms were significantly more often experienced by persons with hypersensitivity to electricity than by persons of the control group. There were no statistically significant differences between cases and controls regarding neurovegetative symptoms. The authors proposed a set of dimensions for characterization of the syndrome hypersensitivity to electricity including skin and neurovegetative symptoms, belief in hypersensitivity to electricity, triggering factors (e.g., visual display unit), duration of symptoms, and behavior (e.g., avoidance of triggering factors).
