Objectives : Electrical acupoint stimulation(EAS) has been used to treat motor dysfunction of stroke patients with reportedly effective results. The purpose of this study is to evaluate the efficacy of the EAS with different frequencies in treating motor dysfunction of ischemic stroke patients. Methods : The subject of this study were forty-two ischemic stroke patients with motor dysfunction in Kyunghee oriental medicine hospital who were hospitalized for one week to one month from onset. They were treated with 2Hz or 120Hz EAS for two weeks, and motor evoked potentials(MEP) were measured before and after EAS treatment. To compare the effect of 2Hz EAS with 120Hz, the number of patients who showed MEP responses after two weeks among those who had no previous response was checked. Also measured were latency, central motor conduction time(CMCT), amplitude of MEP before and after EAS treatment. Results : After two weeks of treatment, 4 out of 15 patients(27%) in the 2Hz EAS group and lout of 19 patients(5%) in the 120Hz group showed potential responses. Yet there was no significant difference between the two groups. When MEP data of the affected side between the 2Hz group and the 120Hz group was compared, the former showed more significant improvement than the latter in latency, CMCT and amplitude(P=0.040, 0.019,0.021). When the proportion of the affected side and unaffected side in MEP data was examined, the 2Hz group showed improvement on only latency and CMCT with significant differences(P=0.040, 0.014). Conclusions : These results show that EAS with low frequency is more helpful for motor recovery after ischemic stroke than that with high frequency. This suggests that low frequency EAS activates the central motor conduction system better than high frequency EAS.
