Evaluate Laser Needle Effect on Blood Perfusion Signals of Contralateral Hegu Acupoint with Wavelet Analysis
Figure 4
Change of average amplitude in left Hegu acupoint. The change of average amplitude is defined as . All data expressed as Mean ± SEM. NH-S: Non-Hegu stimulation; H-S: Hegu acupoint stimulation; (a) shows the frequency interval of 0.0095–0.02 Hz; (b) shows the frequency interval of 0.02–0.06 Hz; (c) shows the frequency interval of 0.06–0.15 Hz; (d) shows the frequency interval of 0.15–0.4 Hz; (e) shows the frequency interval of 0.4–1.6 Hz; *, H-S versus NH-S.
