Study on the Effect of Electroacupuncture at Both Zusanli and at Both Yanglingquan Acupoints on Cardiovascular Activity

Study Overview
=================
Brief Summary
-----------------
The purpose of this present study was to investigate the effect of electroacupuncture at both Zusanli and at both Yanglingquan acupoints on autonomic nerve modulating cardiovascular activity, and skin blood flow and skin temperature. The investigators use pulse rate variability to investigate autonomic nerve modulates cardiovascular function, and using distant skin blood flow and skin temperature recordings to investigate the relationship between the same names meridian of hand and foot.

Detailed Description
-----------------
A total of 24 adult healthy volunteer were studied, they received the three sessions of sham electroacupuncture, electroacupuncture at Zusanli and electroacupuncture at Yanglingquan, respectively. Each session was divided into three periods of before electroacupuncture, electroacupuncture, and post electroacupuncture. Each period was 20 min in duration. The ahead 15 min of the period was the skin blood flow and skin temperature recordings at Hoku's and Zhongzhu's region of right hand; the final 5 min of the period was pulse rate variability recordings of left hand. The data was storage and analysis in a personal computer.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| From pulse wave, pulse rate variability and skin blood flow to measure cardiovascular activities with electroacupuncture at Zusanli and at Yanglingquan. | Each session was divided into three periods of before electroacupuncture, electroacupuncture, and post electroacupuncture. Each period was 20 min in duration. During each period, the final 5 min of the period was pulse rate variability recordings of left hand by ANSWatch(TS-0411 model). This data were storage as primary outcomes and analyzed in a personal computer. | each period was 20 min in duration. The parameters of pulse wave, 5-min pulse rate variability were recorded at the end of each period. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| From skin blood flow and skin temperature to measure cardiovascular activities with electroacupuncture at Zusanli and at Yanglingquan. | Each session was divided into three periods of before electroacupuncture, electroacupuncture, and post electroacupuncture. Each period was 20 min in duration. During each period, the ahead 15 min of the period was the skin blood flow and skin temperature recordings at Hoku's and Zhongzhu's region of right hand by Laser doppler blood flow monitor (Moor instruments DRT4 model). This data were storage as seconrdary outcomes and analyzed in a personal computer. | each period was 20 min in duration. The parameters of skin blood flow and skin temperature were recorded at the end of each period. |
