In the first experiment (Exp. 1), a miniature telemetric thermal stimulator system was designed and validated with capsaicin-induced, short term hypersensitivity tests in simultaneous TPT measurements on the fingertips of the two index fingers in 20 healthy human volunteers in a single blind experimental arrangement. In the second experiment (Exp. 2), 10 new volunteers were recruited for an EMF provocation study. In a single-blind task design, subjects were exposed to either genuine or sham irradiation in two separate sessions (genuine EMF or SHAM) with at least one week break between the sessions. In each session, 6 blocks of 3 TPT trials were recorded on the tips of each index finger. Experimental data were recorded at –30, 0, 15, 30, 60 90 min. EMF/SHAM exposure lasted from 0-30 min. Results of Exp. 1 indicate that the newly designed measurement system was successfully validated with hypersensitivity inducing agent capsaicin. Our preliminary results from Exp. 2 support the notion, that a single 30 min irradiation from new generation 3G mobile phones may not induce measurable changes in TPT or VAS pain ratings in the given time window of the experimental design. The present results indicate that a single exposure to 3G mobile phones does not interfere with basic somatosensory mechanisms in healthy human subjects.
