Testing the bioelectric shield. med./bio.

Published in: Altern Ther Health Med 2002; 8 (5): 62-67

Aim of study (acc. to author)

To present three tests of a device (BioElectric Shield; BioElectric Company, Lavina, Mont) supposed to have widespread therapeutic and protective powers. The effectiveness as a bioelectric shield was studied.

Background/further details

The shields are attractive silver and gold pendants that hang around the neck on a fine silk cord.
In the first experiment, 12 subjects who work with computers wore shields (6 real, 6 sham) for several weeks. In two further studies (in each N=40) hand strength was measured at baseline, with mobile phone, and with mobile phone and bioelectric or sham shield.

Main outcome of study (acc. to author)

In the first experiment both types of shield increased calmness, but the real shields did not have any greater effect.
In the two further studies the shields did not differ in their effects. Both studies revealed a significant correlation between the change in strength with and without the shield and subjects' scores on a questionnaire concerning their belief in and use of alternative therapies. The shields appear to produce a measurable placebo effect but are otherwise ineffective.
