Methods: 76 patients were randomly divided into treatment group (n=43) and control group (n=33).In teatment group, penetration needling from Qiuxu (丘墟 GB 40) to Zhaohai (照海 KI 6) was performed, combined with electrical stimulation for 30 min. Patients of control group were ordered to take Antinfan (50 mg,b.i.d.),supplemented with local external application of Votalin cream (b.i.d.).After 14 treatments (two courses), the therapeutic effect was assessed. Results: Following two courses of treatment, of the 43 cases and 33 cases in treatment and control groups,33 (76.7%) and 15 (45.5%) were cured, 4 (9.3%) and 7 (21.2%) had marked improvement in their symptoms, 3 (7.0%) and 2 (6.1%) had improvement, and 3 (7.0%) and 9(27.3%) failed, with the effective rates being 93.0% and 72.7% respectively. The therapeutic effect of treatment group was significantly superior to that of control group (P<0.05). Conclusion: Penetrative needling plus EA is significantly superior to medication in relieving chronic ankle spain patient’s clinical symptoms and signs.展开更多
