Objective To observe the clinical efficacy of HE’s three dredging needle methods in treating Wallenberg syndrome. Methods Twenty eight acute dorsolateral medullary infarction patients with Wallenberg syndrome were randomly divided into HE’ s three removing obstruction methods group and routine acupuncture group

with 14 cases in each group. HE’s three dredging needle methods group was given combined treatment of micro-removing obstruction method

warm-removing obstruction method and strong-removing obstruction method. Routine acupuncture group was given routine acupuncture treatment. The two groups were both treated 5 times each week for 4 weeks.Modified Rankin Scale（ MRS）

the Barthel index of ADL（ BI）

Stroke Specific Quality of Life Scale（ SS-QOL）

water swallow test

and Standardized Swallowing Assessment Scale（ SSA） were measured in the two groups to evaluate neurologic function and swallowing function of patients before and after treatment and at the time of followed up（ 20 weeks after treatment）. Results There was no significant difference in all indexes in the two groups between before treatment and after 4 weeks of treatment（ P > 0. 05）

and there was also no significant difference in those indexes between the two groups（ P > 0. 05）. At the time of followed up

MRS

BI and SS-QOL scores in the two groups

as well as the results of water swallow test and SSA scores in HE’s three removing obstruction methods group were all observably improved compared with those before treatment（ P < 0. 05 or P < 0. 01）

and the results of water swallow test and SSA scores in HE’s three removing obstruction methods group were better than those in routine acupuncture group（ P < 0. 01）. Conclusion HE’ s three dredging methods could effectively improve swallowing function of Wallenberg syndrome patients

and the long-term effect of HE’s three dredging methods seems better than that of routine acupuncture.
