Figure 2

Experimental diagram. Before needle insertion (ins) and stimulation (stim) bilaterally at ST36, LR3, and the non-acupoint. After the needles were inserted, needle stimulation was applied for 18 s with manual rotation. The needles were retained for 180 s after needle stimulation and then removed. Hemodynamic parameters were measured before needle insertion, during, and 30, 60, and 180 s after needle stimulation. min.: minutes, s: seconds.
