Evaluate Laser Needle Effect on Blood Perfusion Signals of Contralateral Hegu Acupoint with Wavelet Analysis

Figure 2

Change of MBF in left Hegu acupoint. All data expressed as Mean ± SEM. NH-S: Non-Hegu stimulation; H-S: Hegu acupoint stimulation; (a) shows the average blood flux in NH-S group and H-S group, **𝑃<0.01, R1 versus R4; ^##𝑃<0.01, R4 versus R8. (b) shows the change of MBF in different time period, which defined as (𝑅_𝑖−𝑅₁)/𝑅₁(𝑖=1,2,3,…,8). In every time, the change of MBF between two group has not significant difference (𝑃>0.05).
