Abstract
Background
The Zusanli(ST36) point, as one of the key health care points, has a wide range of indications and various effects. Given its effectiveness in regulating qi and blood flow, we investigated its direct impact on the arteries of the lower limbs. Earlier research indicates that the ST36 may enhance blood flow to the anterior tibial artery, yet there's a need to refine its research methodology and key findings. Consequently, our objective was to thoroughly investigate how the ST36 influences the blood flow dynamics in the arteries of the lower limbs.
Methods
This is a randomized, single-blind, and parallel controlled study. Participants will be evenly distributed in a 1:1 ratio between the interventional group (true acupuncture guided by ultrasound) and the control group (sham guided by ultrasound). Key metrics such as blood flow volume, peak systolic velocity, arterial diameter, and C-MASS evaluations will be documented and monitored pre and post-treatment. Ultimately, the analysis of the data was conducted utilizing the SPSS 25.0 software.
Discussion
Through this study, we aim to gain a deeper understanding of the hemodynamic effects of ultrasound-guided acupuncture at ST36, and hope to provide new treatment methods and scientific basis for lower limb arterial vascular lesions.
