Abstract

Objective : To study correlation of the brain areas with acupoints used in the treatment of cerebrovascular diseases to evaluate the hypothesis that selecting acupoints on the left side to treat disorders on the right side and vice versa is known as the crossing combination of acupoints.
Materials and Methods: Rest/acupuncture-stimulation Tc-99m ECD brain SPECT using a same-dose subtraction method was performed on 5 normal male volunteers (age range from 27 to 30 years) using acupuncture at acupoint, L14 located in the left hand. In the control study, needle location was chosen on a non-meridian focus 1cm posterior to the right fibular head. All images were spatially normalized and the differences between rest and acupuncture stimulation were statistically analyzed using SPM® for Windows®.
Results : Acupuncture applied at L14 located in the left hand increased rCBF in the right hemisphere, that is, the right parietal lobe(angular gyrus) and a part of the right middle posterior temporal gyrus and the right inferior occipital lobe. In the control stimulation, no significant rCBF increase was observed.
Conclusion : The results demonstrated a correlation between stimulation at acupoint with increase in rCBF to the controlateral hemisphere.
