研究目的(著者による)

To investigate the effects of radio frequency exposure with a CDMA cellular phone on autonomic changes (e.g. heart rate) in an electromagnetic hypersensitivity group and whether electromagnetic hypersensitivity resulted from autonomic changes.

詳細情報

18 electromagnetic hypersensitivity volunteers (8 males) and 19 normal volunteers (10 males) were exposed and sham-exposed during two days in randomized order. Physiological data were collected at four different times: during rest, after 15 min continuous exposure, after 31 min continuous exposure, 10 min after exposure termination.

研究の主なアウトカム(著者による)

The radio frequency exposure by a CDMA cellular phone did not have any effects on the physiological parameters for both groups. Regarding the subjective symptoms, both groups did not significantly differ between real and sham exposure. The perception accuracy of the exposure and sham exposure for the electromagnetic hypersensitivity group was 42.2 % and 73.9% and for the control group 3.0% and 95.1%.
The results on perception accuracy could be attributable to the fact that many subjects in the electromagnetic hypersensitivity group answered "Yes" to the question "Do you feel the electromagnetic field?" because they thought as if they could feel the electromagnetic field.In contrast, the control group revealed higher accuracy in perception to the non-exposure because they considered themselves that they could not feel electromagentic fields.
