(A) Experimental design. All participants received acupuncture or tactile stimulation at four different points (HT7, PC6, ST36, and SP10) on their left side. In each session, they were asked to evaluate the characteristics of DeQi sensations from the body and to mark the areas of the acupuncture-induced sensations using the BSM device. (B) Participants were asked to draw their bodily sensations using the BSM system. The BSM system was used to gather spatial information on the acupuncture sensations (Data collection). We calculated the statistical significance of associations between each condition and the spatial configuration of the acupuncture-induced sensations (Data analysis). We visualized the spatial distribution of acupuncture-induced sensations using the human body template by applying Z scores (Data visualization).
