Objective : To ascertain whether the concept of the treatment side is associated with changes in the blind spot mapping that represents the brain function.
Methods : Among the outpatients who visited to Department of Acupuncture & Moxibustion, National Medical Center from March 2002 to October 2002, we selected 40 clinical trial volunteers that showed right side physiological blind spot more enlarged than left, and underwent the examinations of Department of Opthalmology, National Medical Center for ruling out the pathological conditions. Physiological blind spot maps were used as an integer of brain activity before and after electroacupuncture application on the unilateral ST36 meridian point by dividing 40 subjects into two comparative groups for double-blind controlled study.
Results: The significant changes in the blind spots were observed. Electroaupuncture application on the ipsilateral or cintralateral ST36 of an enlargement cortical map were associated with the concept of determining the treatment side. In the case of electroacupuncture application on the ipsilateral side of an enlarged blind spot, there were decrease of 4.11±8.56cm(17.3%) in blind spot perimetry length(p < 0.05). In the case of contralateral side, there were increase of 3.19±5.40cm(13.7%) in blind spot perimetry length(p<0.05).
The Differences were statistically significant(p<0.05).
Conclusions: We found that eletroacupuncture application was associated with an increase or decrease in the brain function in the view of blind spot changes depending on the treatment side. These results suggest that the traditional acupuncture therapeutic strategy with determining the treatment side has clinical significance in the view of the brain function.
