Objective: The electroacupunture(EA) is frequently used to enhance stroke rehabilitation. Many studies about spasticity after stroke with EA were undergone. But mainly the elctrophysiologic character of EA is compared such as the frequency, waveform, intensity and voltage of EA stimulation. There is no study that what is more effective the EA on Yin or Yang meridians to spastic patients after stroke in traditional concept. So we compared the effect between Yin and Yang meridians EA to the stroke spasticity.
Methods: 53 spasticity patients with hemiplegic stroke were randomized into two groups. 27 patients were treated by the EA on Yin meridians for elbow joint spasticity(named Yin EA group). The other 26 patients were treated by the EA on Yang meridians(named Yang EA group). The frequency of stimulation was 2Hz and the intensity was set at a level sufficient to include muscle contraction during 3 weeks. Outcomes were assessed by modified Ashworth scale, Fugl-Meyer score and modified Barthel index.
Result: In terms of spasticity, only Yang meridians group showed statistically significant improved, in terms of motor function, Yin meridians group is significantly more effective than Yang meridians group, and in terms of ADL, comparision between Yin and Yang meridians group is not significantly meaningful.
Conclusion: These results support that the effect of Yin and Yang EA on stroke patients is classified. For antispastic effect the Yin meridians EA is more effective and for motor rehabilitation Yang meridians EA is more effective.
