研究目的(著者による)

To investigate the baseline neurophysiological characteristics of the central and autonomous nervous system regulation and their reactivity to different functional tests in patients with perceived electrosensitivity in comparison to a control group.

詳細情報

20 hypersensitive patients and 20 control subjects participated in the study. The neurophysiological parameters were measured before and during the functional tests (e.g., heart rate during rest and standing). Electromagnetic field exposure was not performed, but the groups were characterized.

研究の主なアウトカム(著者による)

Several neurophysiological variables were found to differ between the hypersensitive patients and the control group. The mean value of the heart rate in rest condition was higher in the patient group compared to the control group whereas heart rate variability and response to the functional test were decreased in the patient group. Patients also showed differences in the electrodermal activity and in the visual evoked potentials. They had a higher critical fusion frequency.
The authors concluded that the observed group of patients had a trend to a hypertone of the sympathetic nervous system, hyperresponsiveness to sensor stimulation and heightened arousal.
