The effects of a 2-hr exposure to a weak, oscillating magnetic field on nociception were studied in pigeons and men by measuring the threshold for electric stimuli. In pigeons, the magnetic treatmen inhibits stress-induced analgesia and also produces hyperalgesia with respect to the baseline. In humans, an hyperalgesic effect in non-stressed conditions is shown by the lowering of three thresholds (for dental sensitivity, cutaneous pain, and cutaneous tolerance), while two further thresholds (for dental pain and cutaneous sensitivity) showed the same tendency.


Gli effetti dell’espo-sizione per 2 ore a deboli campi magnetici oscillanti sulla nocicezione sono stati studiati nei colombi e nel-Tuomo misurandone la soglia di sensibilità agli stimoli elettrici. Nei colombi, il trattamento magnetico di-minuisce Fanalgesia indotta da stress e produce iperalgesia rispetto ai valori basali. Nell’uomo è stato rile-vato un effetto iperalgesico anche in condizioni non stressanti: le soglie per la sensibilità dentale, per il do-lore cutaneo e per la tolleranza cutanea sono risultate significativamente più basse, mentre altre due soglie, quella per il dolore dentale e per la sensibilità cutanea, hanno mostrato solo una tendenza a decrescere.
