Objective  To observe the clinical efficacy of encephaloduroarteriosynangiosis (EDAS) combined with intermediate frequency electrotherapy in children with ischemic moyamoya disease.

  Methods  A total of 50 patients with ischemic moyamoya disease were selected as study objects, and were randomly divided into control group and treatment group according to random number remainder grouping method, with 25 cases in each group. The control group was treated with EDAS, and the treatment group was treated with intermediate frequency electrotherapy instrument on the basis of the control group. The blood flow velocity of the internal and external carotid arteries was detected by transcranial Doppler ultrasonography, and the nerve function, limb function and living ability of the two groups were compared, and the clinical efficacy of the two groups was observed.

  Results  After treatment, the internal carotid artery, external carotid artery branch and modified Rankin scale (mRS) score in the treatment group were lower than those in the control group(P < 0.05). After 1 month of treatment, Brunnstrom score, Fugl-Meyer Assessment Scale (FMA) score and Barthel index (BI) score in the treatment group showed significant difference compared with those in the control group (P < 0.05). The total effective rate in the treatment group was higher than that in the control group (P < 0.05).

  Conclusion  Compared with EDAS therapy alone, medium frequency electrotherapy and EDAS therapy is more effective in improving the neurological function, limb function and living ability of patients with ischemic moyamoya disease.
