초록

Objectives : The elicit of DeQi, a composite of sensation including numbness and fullness that develops at the site of acupuncture stimulation, is considered to be clinically essential to establish treatment efficacy. However, there was little studies investigating the relationship between the subjective feeling of acupuncture sensation and acupuncture analgesia, The current study was therefore performed to determine the correlation between the acupuncture sensation scale (ASS) and the degree of acupuncture analgesia. Methods : Ninety-two female subjects were stimulated at LI4 acupoint on non-dominant hand with real (RA) or sham acupuncture (SA). Finger withdrawal latency (FWL) of each group was also measured to evaluate analgesic effect of acupuncture on the noxious heat stimuli on the dominant hand. All subjects were asked to complete seven point-Likert scale ASS developed by Vincent et al. Results : The increase rate of FWL of the RA group was significantly higher than that of the SA group(36.03 ${\pm}$ 4.45% vs 24.50 ${\pm}$ 3.73%). RA stimulation produced significantly higher rating of all the ASS except for dull sensation, compared to SA stimulation. Significant correlations between analgesic effect of RA, but not of SA, and the degree of the ASS, including burning sensation(r=0.349), Intense sensation(r=0.299), pulsating sensation (r=0.335), and stinging sensation (r=0.306) were found. Conclusions : The results of our study indicate that the DeQi sensation are associated with acupuncture analgesia. Our findings suggest that the evocation of DeQi might be useful clinical indicator of acupuncture treatment.
