ABSTRACT

<p><b>OBJECTIVE</b>To explore effects of electroacupuncture of different frequencies on stroke.</p><p><b>METHODS</b>Forty-seven cases of stroke were treated with electroacupuncture at the motor region of the scalp and divided into 2 Hz, 2/15 Hz and 100 Hz groups according to the used frequency. Cerebral blood perfusion and brain functions before and during electroacupuncture in the 3 groups were investigated with single photon emission computed tomography (SPECT).</p><p><b>RESULTS</b>Local cerebral blood perfusion and brain cell functions could be improved by electroacupuncture of the 3 frequencies, and the actions of 2/15 Hz and 100 Hz were better.</p><p><b>CONCLUSION</b>Electroacupuncture of 2/15 Hz and 100 Hz has a better therapeutic effect on stroke when the stimulating intensity is fixed.</p>
