The purpose of this study was the evaluation of the effectiveness in the improvement of the psychic and symptomatic stress-related disorders by means of radio-electric stimulation on some auricular reflex points with a device named the radio-electric asymmetric conveyer (REAC). This study was conducted on 124 subjects with psychological distress symptoms that were assessed by the Symptomatic Check List-90 (SCL-90) pre- and post-intervention. After randomization, two groups were created: a group treated with effective REAC and a group that underwent the same treatment with disarmed REAC (the placebo group). There was a significant reduction in SCL-90 scores in the treated group compared with the placebo group. The results of the psychometric tests showed that the subjects who underwent effective therapy showed a statistically significant (p < 0.05) reduction in their level of stress and psychological disorders compared with the control group. The reduction of the levels of perceived stress and the reduction of the psychic and symptomatic stress-related disorders assessed by SCL-90 tests, obtained after one cycle of reflex auricular protocol REAC treatment, showed that this treatment can be useful in the cure of psychological stress-related symptoms.
