To examine whether motor responses are generated in sensitive persons, when they move across a set of standing waves caused by irradiation from a FM-radio and TV-tower.
29 adults of different ages were tested (they participated in a seminar on effects of electromagnetic fields, thus they possibly do not represent a normal population).
The connection between the hand movements and the intensity of electromagnetic field of a transmitter were recorded. Subjects were standing near a reflector: when the reflector was moved, the position of the maximum of the standing waves changed and the electromagnetic intensity changed in the body of the subject. Electromagnetic exposure was assessed by a radio frequency-meter.

| Distance between exposed object and exposure source | 5 km |
| Setup | 3 m x 5 m moveable reflector wall constructed of a wooden frame and stell net, the wall was positioned 2 m from the back of the test person and moved 20 m back and forth |
| Additional info | intensity of electric field measured with a broadband RF-meter with horizontal dipole antenna |
No parameters are specified for this exposure.
There were 9 persons whose hand movement graphs included features like the graph of the radio frequency-meter. 6 showed responses that did not correlate with the radio frequency-meter. 14 persons did not react at all.
Sensitive persons seem to react to crossing standing waves of the FM-radio or TV broadcasting signals.
