All the patients were evaluated with SDS and P300 potentials test at 1 week (the first evaluation) and 6 weeks (reevaluation) after treatment.latencies of N1, P2, N2 and P3 waves and amplitude of P3 wave in P300 potentials.RESULTS: All the patients in the treatment group (n=41) and control group fore treatment, the scores of SDS and the results of P300 potentials were not Reevaluation: After treatment, the score of SDS in the treatment group was significantly lower than that in the control group (40.32±7.2, 48.31±8.02,t=3.89, P ＜ 0.01); the latencies of N2 and P3 waves in P300 potentials test in the treatment group were obviously lower than those in the control group [(235.5±22.9), (248.3±23.4) ms; (339.1±25.3), (348.6±25.5) ms, P ＜ 0.05],and the amplitude of P3 wave was obviously higher than that in the controlgroup [(6.3±1.9), (4.9±2.0) μV, P ＜ 0.05].
