Clinical trials of treatment of post-stroke foot drop by fire-needling plus stuck-needle-stretching

Abstract

To compare the therapeutic effect of fire-needling plus stuck-needle-stretching and conventional acupuncture for post-stroke foot drop, so as to provide a reference foundation for optimizing clinical treatment regimen. A total of 60 patients with post-stroke foot drop were equally randomized into a treatment group and a control group. In the treatment group, fire-needling plus stuck-needle-stretching was applied to acupoint pairs Jiexi (ST41)-Taichong (LR3), Xiajuxu (ST39)-ST41, Fenglong (ST40)-ST39, shangjuxu (ST37)-ST40, Zusanli (ST36)-ST37, Dubi (ST35)-ST36, Xuanzhong (GB39)-Qiuxu (GB40) on the affected side, and Chengshan (BL57) and Ashi points were swiftly pricked with red-hot filiform needle without needle retaining. In the conventional acupuncture group, the same acupoints were needled with filiform needles, and the treatment for both groups was given once a day, 6 times a week, for consecutive 4 weeks. The spasm severity of posterior triceps of the lower leg was evaluated using modified Ashworth scale, the tibial anterior muscle strength was measured using Lovett' and Martin's methods, the activities of daily living were assessed using modified Barthel's index, the walking ability was evaluated using Holden walking rating scale and the lower limb motor function assessed using Fugl-Meyer assessment scale, and the severity of foot drop was assessed in reference to Garceau criteria. After the treatment, the score of the modified Ashworth scale was significantly reduced (P<0.01), and those of Lovett muscle strength scale, Barthel index, Holden walking rating scale and Fugl-Meyer lower limb motor function scale were considerably increased in both groups versus their own pre-treatment (P<0.01). The therapeutic effect of the treatment group was significantly superior to that of the control group in reducing Ashworth scale score and in increasing the scores of Lovett muscle strength test, Barthel index, Holden walking function scale and Fugl-Meyer lower limb motor function scale (P<0.01). Of the two 30 cases in the control and treatment groups, 10(33.33%)and 14(46.67%) experienced a remarkable improvement, 10(33.33%)and 12(40.00%)were improved, 7(23.33%)and 3(10.00%)had a mild progress, 3(10.00%) and 1(3.33%) failed, with the excellent plus good effective rates being 66.67% and 86.67%, respectively, but without significant difference between the two groups (P>0.05). Both fire-needling plus stuck-needle-stretching and conventional acupuncture are effective in the treatment of post-stroke foot drop, but the former is relatively better.
