Résumé
<p><b>OBJECTIVE</b>To compare the clinical efficacy difference in dysantonomia between transcutaneous electrical stimulation at Renying(ST 9) combined with stellate ganglion block(SGB) and simple SGB.</p><p><b>METHODS</b>Sixty patients in accord with the diagnostic criteria of dysantonomia were randomly divided into two groups,30 cases in each group. In the observation group,transcutaneous electrical stimulation at Renying(ST 9) combined with SGB were adopted; in the control group,simple SGB was applied. In the two groups, treatment was used three times a week,and nine treatments were considered as one course. There was an interval of one week between courses,and two courses were treated. Total seven weeks were required. Scores were evaluated according to subjective symptoms before treatment,one month and three months after treatment in the two groups.</p><p><b>RESULTS</b>The scores of subjective symptoms were not statistically different before treatment in the two groups(P>0. 05). The scores of subjective symptoms one month and three months after treatment were all lower than those before treatment(all P< 0. 01), and subjective symptoms scores in the observation group were lower than those in the control group(both P<0. 01).</p><p><b>CONCLUSION</b>Transcutaneous electrical stimulation at Renying(ST 9) combined with SGB could obviously enhance the clinical effects for dysantonomia, and the control and improvement for clinical symptoms are apparently superior to simple SGB.</p>
