Hemodynamic Changes in the Brachial Artery Induced by Acupuncture Stimulation on the Lower Limbs: A Single-Blind Randomized Controlled Trial

Figure 4

Percent change in the systemic vascular resistance index before needle insertion (ins) and at stimulation (stim) at ST36, LR3, and the non-acupoint. Values represent means and standard errors (SEM). ^{*, **} Significantly different (𝑃<0.05, 𝑃<0.01, resp.) relative to the resting condition in each test setup.
