Background Recently, porous acupuncture (PA), which is anodized to increase its surface area for higher stimulation intensity, was developed and showed significantly improved therapeutic effects with more comfort as compared original (OA) in vivo. However, the impact of PA on change local blood flow well efficacy acceptability has not yet been confirmed a clinical trial. In randomized, controlled crossover trial, we investigated using laser Doppler perfusion imaging considered sensation pain intensity discomfort severity visual analogue scale (VAS) explore physiological possibility use. Methods Twenty-one healthy participants were randomly treated or OA one side Zusanli (ST36) each participant served his her own control. Baseline galvanic skin response (GSR) obtained 5 min interventions subsequently performed. Next, GSR 10 after insertion, manipulation, withdrawal acupuncture. At end experiment, asked indicate at session retention, overall severity. Results increased there no significant difference between patients versus phase insertion manipulation. No found during Conclusions These results that increases flow, can be closely related observed enhanced performance, without any associated pain, suggesting applicability practice.
