OBJECTIVE: To observe the effects of different lengths of needle-retaining time on the therapeutic results of acupuncture treatment for ischemic wind-stroke. METHODS: According to the severity of disease, 251 cases of ischemic wind-stroke were randomly divided into 3 groups and treated by acupuncture, with the needle-retaining time lasting 20, 40, and 60 minutes respectively. Observation was mainly focused on the scores of nervous dysfunction and the clinical therapeutic results. RESULTS: The comparison of the scores of nervous dysfunction in the 3 groups before and after the treatment showed that under Wilcoxon's pair-match symbol rank test, except for horizontal gaze, other indexes all showed significant differences (P < 0.01). In the between-group comparison before and after the treatment, there showed significant or very significant differences in the indexes of myodynamia of the upper limb, myodynamia of hand and the total scores (P < 0.05, P < 0.01). In the between-group comparison by Mann-Whitney rank test of the indexes of myodynamia of upper limb, myodynamia of hand and the total scores, the 20-min. group and the 60-min. group showed significant differences (P < 0.05); and 40-min. group and 60-min. group showed significant differences in myodynamia of upper limb (P < 0.05). In comparison of the therapeutic effects of the 3 groups by Kruskal-wallis rank test, there showed very significant differences (P < 0.01). In the between-group comparison by Mann-Whitney rank test, the 40-min.group and 60-min. group showed significant differences (P = 0.013); while the 20-min. group and 60-min. group showed very significant differences (P = 0.000). CONCLUSION: There is a time-effect relationship between the length of needle-retaining time and the therapeutic effects of acupuncture for ischemic wind-stroke.
