Objective : This study was designed to compare acupuncture sensation index among three different acupuncture devices. Methods : A, B and C acupuncture devices were inserted into Quchi(LI 11) of the subjects. After 5 minutes the subjects completed a questionnaire rating the intensity of 21 kinds of acupuncture sensation; hurting, penetrating, sharp, aching, intense, spreading, radiating, tingling, pricking, stinging, pulling, heavy, dull, numb, electric, shocking, hot, burning, cool, pulsing, and throbbing. We compared subjective evaluations of acupuncture sensation among the groups. Results : The acupuncture sensation index when administrated among three different acupuncture devices(A, B and C) was not significantly different. The acupuncture sensation of B acupuncture devices showed significant difference than A or C in Spreading, Dull, Numb item. But, the other items of acupuncture sensation were not significantly different among three acupuncture devices. Conclusions : We found that acupuncture sensation index when administrated among three different acupuncture devices. Further study is needed to know different acupuncture sensation among acupuncture devices.

Objective : To study needling sensation and the flow of the needling sensation the ancient and the present literatures were reviewed. Results : 1. The needling sensation was getting the Qi and a normal reaction of acupuncture. 2. The flow of the needling sensation was promoted the Qi and normalized the flow of the Qi 3. The needling sensation of a patient expressed soreness, distension, heaviness, numbness, tingling, flushing, fervor, chill, itching, and so forth. 4. The needling sensation of a patient expressed simple or complex syndrome. 5. The needling sensation of a doctor expressed objectively more than the needling sensation of a patient in the hand feeling of a doctor. 6. The doctor was compared good needling sensation and bad needling sensation. 7. The needling sensation and the flow of the needling sensation were processed continuously. 8. The needling sensation and the flow of the needling sensation were connected with a nervous system and expressed variously in the anatomical structure and hand acupuncture tenchnique.

Objectives : This study was designed to find out the differences of the acupuncture sensation by body parts. Methods : Sixty-three subjects got acupuncture at five acupoints which represent five different body parts ; head($GV_{20}$), abdomen($ST_{25}$), back($BL_{24}$), upper extremity($LU_9$), lower extremity($GB_{40}$). All subjests were asked to complete questionnaire rating the intensity of 13 kinds of acupuncture sensation(acupuncture sensation scale, ASS). We compared the subjective acupuncture sensation between the body parts. Results : Intensity of acupuncture sensation of $GV_{20}$ was significantly lower than $LU_9$(p=0.001) and $GB_{40}$(p=0.000). Sum of acupuncture sensation of $GV_{20}$ was also significantly lower than $BL_{24}$(p=0.011), $LU_9$(p=0.004) and $GB_{40}$(p=0.033). Among the 13 types of acupuncture sensation scale, tingling and aching were well sensed at $GV_{20}$ and $ST_{25}$, aching, tingling and sharp pain were well sensed at $LU_9$, $GB_{40}$, dull pain, deep pressure and heaviness were well sensed at $BL_{24}$. Conclusions : Head showed significantly lower intensity of acupuncture sensation than upper extremity and lower extremity. Among the acupuncture sensation scales, tingling and aching were well sensed at head and abdomen, aching, tingling and sharp pain were well sensed at upper extremity and lower extremity, dull pain, deep pressure and heaviness were well sensed at back.

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.

Objective : This study was designed to find out whether NS(normal saline) is able to be constituted as an appropriate control group for CC(Cervi Cornu Parvum herbal acupuncture), CF(Carthami-Flos herbal acupuncture) and BV(bee venom herbal acupuncture). Method : NS and three herbal acupuncture were inserted into Quchi(LI 11) of the subjects. After 5 minutes the subjects completed a questionnaire rating the intensity of 21 kinds of acupuncture sensation; hurting, penetrating, sharp, aching, intense, spreading, radiating, tingling, pricking, stinging, pulling, heavy, dull, numb, electric, shocking, hot, burning, cool, pulsing, and throbbing. We compared subjective evaluations of acupuncture sensation between or among the groups. Results : As for CC half items of the acupuncture sensation were significantly different from NS. As for CF all items were not significantly different from NS. As for CC all items were significantly different from NS except one item. In general the score of CF acupuncture sensation was lower than the others and the score of BV acupuncture sensation was higher than the others from comparison of sensation among herbal acupunctures(CC, CF, BV). Conclusion : We found that NS is able to be an appropriate placebo herbal acupuncture for CF. Further study is needed for new placebo herbal acupuncture for CC and BV.

Objectives : Proper acupuncture stimulation is associated with a characteristic set of sensation usually referred to as 'De-Qi'. In order to develop the appropriate sham acupuncture, various sensations to each stimulation should be considered through analysis of the profiles of acupuncture sensation. It was therefore investigated to compare the acupuncture sensation scale (ASS) of two types of sham acupuncture to that of the real acupuncture. Methods : Ninety-four participants (mean age 26.4, range 26-49) were asked to complete five point-Likert scale ASS developed by Vincent et al. after real or two-kinds of sham acupuncture stimulation: blunted tip sham acupuncture (BT) and round tip sham acupuncture (RT). Needling was done at LI4 acupoint on non-dominant hand and stimulated for 30 seconds with real or two-kinds of sham needle. Finger withdrawal latency (FWL) of each group was also measured to evaluate the pain sensitivity to noxious heat stimuli. Results : BT acupuncture significantly less produced penetrating, numb, intense, hurting, pulling, shock, tingling, throbbing sensation than real acupuncture stimulation. RT acupuncture significantly less produced penetrating, burning, electric, numb, intense, hurting, pulling, aching, shasharp, shock, stinging, tingling, throbbing sensation than real acupuncture. Each group did not demonstrate the differences of pain sensitivity to noxious stimuli. Conclusions : These results indicated that types of tip of acupuncture produced different kinds of acupuncture sensation. Our finding provides a general information of sensations to two kinds of sham acupuncture for development of ideal placebo sham needle.

Objectives : In this study, we intended to make the foundation of the development of acupuncture tissue model as comparing the needle sensation of six kinds of tissue models and Zusanli ($ST_{36}$) with the needle force measurement system. Methods : When practitioners did twisting-rotating acupuncture needle manipulation after inserting the needle into six kinds of tissue models, they quantified the similarity sense to the sensation of Zusanli ($ST_{36}$) with the NRS (Numeric Rating scale). As needle force measurement system did twisting-rotating Acupuncture needle manipulation after inserting needle into Zusanli ($ST_{36}$) of human and six kinds of tissue models, it can calculate the coefficient of viscosity by measuring the torsion friction. We compare the NRS of practitioners' needle sensation to the coefficient of viscosity of needle force measurement systems. Result : As practitioners' NRS assessment to quantify needle sensation, apple and cucumber showed 70% similarity to Zusanli ($ST_{36}$). As needle force measurement system's coefficient of viscosity, apple and cucumber's coefficient of viscosity were similar to Zusanli ($ST_{36}$)'s. Conclusions : In this study, We compared the practitioners' needle sensation of Zusanli ($ST_{36}$) and six kinds of tissue models with needle force measurement system that can quantify the needle sensation. As the result, we concluded that practitioners' needle sensation is similar to measured needle sensation. It seems that the acupuncture practice model implementing the needle sensation to specific acupuncture points can be built based on the system in this study.

Objectives: The purpose of this study was to investigate the differences in kind, intensity and depth of de Qi sensation by patients' gender, age, BMI and sensitivity. Methods: Sixty-four healthy volunteers (mean age $26.51{\pm}4.72$, range 22-39) who had been studying anatomy, meridianology, acupuncture & moxibustion for more than five years at Dongguk University, Go-yang, Korea, were invited to take part in an investigation of the sensations associated with acupuncture needling. Needling was self-administered on Hegu (LI4) in the hand and Zusanli (ST36) in the leg randomly. After obtaining de Qi, the participants were asked the kind, intensity and depth of de Qi sensation. Results: There was no statistically significant difference in the kind of de Qi sensation found by acupoints and needling methods (p>0.05). Hegu (LI4) was found to be significantly higher in the intensity (p<0.001), and the depth of de Qi sensation was significantly higher in Zusanli (ST36) than Hegu (LI4) (p<0.001). There was statistically significant difference found in the intensity of de Qi sensation by depth and sensitivity (p<0.05). In the depth of de Qi sensation, there was statistically significant difference found by sensitivity (p<0.05). In de Qi sensation of practitioners, there was statistically significant difference found by gender, BMI, the intensity of de Qi sensation (VAS) and sensitivity. Conclusions: Further study involving acupuncture de Qi sensation and the influencing factors is needed.

Objectives : This study was designed to find out whether normal saline(NS) acupuncture is able to be constituted as an appropriate control group for Cervi Cornu Parvum herbal acupuncture(CC). Methods : NS and CC were injected into Quchi($LI_{11}$) of the subjects. The subjects completed a questionnaire rating the intensity of 21 kinds of acupuncture sensation(hurting, penetrating, sharp, aching, intense, spreading, radiating, tingling, pricking, stinging, pulling, heavy, dull, numb, electric, shocking, hot, burning, cool, pulsing, and throbbing) and side effects. We compared subjective evaluations of acupuncture sensation and side effects between two groups. Results : As for CC most of the acupuncture sensation items were not significantly different from NS especially in less acupuncture-experienced subjects(average 2, below 10 time experiences) rather than more acupuncture-experienced subjects(above 10 time experiences). Conclusions : We found that NS might be an appropriate placebo herbal acupuncture for CC in small amount of acupuncture-experienced subjects. Further study is needed for new placebo herbal acupuncture for CC in more acupuncture-experienced subjects.
