The 501 patients were grouped in 3 groups in terms of De Qi or not De Qi in one side(unilateral)or both sides(bilateral) of the body: bilateral De Qi group, unilateral De Qi group, and non-De Qi group. The abdominal pains were measured using visual analog scale(VAS).RESULTS: In 501 patients, 472 acquired De Qi at unilateral acupoints, 24 De Qi at bilateral acupoint,and 5 had no De Qi at any acupoint. The data of non-De Qi group was excluded as the sample was less than 5% of that in the bilateral De Qi group.There was significant difference in the VAS before and after treatment between unilateral and bilateral De Qi group(P < 0.01). After stratified by acupoints, for the patients needled at Sanyinjiao(SP 6)and Xuanzhong(GB 39), VAS scores in the bilateral De Qi group were larger than those in the unilateral De Qi group(P < 0.05).CONCLUSION: Bilateral De Qi was possibly superior to unilateral De Qi in enhancing the immediate analgesic effect of needling the acupoints, but no statistical significance was observed on the pa-tients of needling at non acupoint, which preliminarily suggested this immediate analgesic effect was perhaps along meridians.展开更多

De Qi comprises needling sensations felt by the patient, and the sensations perceived by the acupuncturist. Classical Traditional Chinese Medicine theory states that De Qi is closely related to curative effect.In modern studies, the main index that researchers have used to evaluate De Qi was the needling sensation reported by the patient. Between 1 st Aug and 31 st Oct 2014, we conducted an electronic database search of all fields in Chinese and English to select literature assessing acupuncture needle sensations. We then reviewed the methods used within these studies to evaluate De Qi. The methods included simple evaluation, and the use of a De Qi scale/questionnaire. The simple evaluation, a qualitative evaluation, was judged by typical sensations felt by the patient after needling at acupoints, such as soreness, numbness, fullness, and heaviness.This method was easy and practicable, and had been adopted widely by Chinese researchers. In contrast, the De Qi scale/questionnaire, a quantitative evaluation, had multiple compiling methods available for evaluating the intensity of De Qi. The standardization and objectification of the De Qi scale/questionnaire effectively improved the quality of studies on De Qi, thereby these scales/questionnaires have been acknowledged and applied by most researchers. The present review analyzed and compared the scales/questionnaires used to evaluate De Qi; furthermore, we provided suggestions for the development and improvement of these questionnaires through integration with classical De Qi theory.展开更多
