Microcurrent electrical fields are known to influence cellular functions. Salivary α-amylase (sAMY) is secreted in response to physical and psychosomatic stress and is an indicator of sympathetic or adrenergic activity. The purpose of this study was to assess the effect of microcurrent treatment on psychological stress by monitoring the time course of sAMY activity. Adult patients with sAMY levels exceeding 30 kU/l were considered eligible for the study. The subjects were randomly assigned to control (n=54), sham (n=54), and experimental (n=54) groups and were examined before treatment and at 35 and 65 min after the treatment. Significant differences in psychosomatic characteristics were observed in the 3 groups (p=0.0046). In the experimental group, the sAMY levels at 65 min after the treatment were significantly lower than those before the treatment or at 35 min after the treatment. These results suggest that microcurrent treatment may be effective in ameliorating psychosomatic stress, which was reflected by the reduction in sAMY activity.
