Real-time samples of impedances at ST-36, GB-34, and a NAP

Published: 15 Apr 2018 | Version 1 | DOI: 10.17632/fwfysz9x52.1

Description of this data

The impedances at right and left ST-36, GB-34 and a non-acupoint (NAP) were sampled at the rate of 1KHz for 5 minutes while the subject sat in a chair, relaxed. The included charts show the results, which are analysed in detail in a paper (“The electrical anatomy of acupuncture points”) which is currently in preparation.

Steps to reproduce

The session began at 10:34am on 29 March 2018.
The subject was a male, aged 58, with poor stomach and pancreas function, who was sat in a chair relaxed. The acupoints were first located by and experienced TCM practitioner, then the locations of lowest impedance verified electrically. For each acupoint, the impedance was measured at the centre, and also at 6mm radius.
The signal used was a 200mv sine wave at 40 KHz. This was passed into the electrodes and the resultant voltages monitored at a sampling rate of 1KHz for 5 minutes. The samples were recorded by a data logger, then imported into Matlab and filtered to produce the plots included here. The data logger was controlled by a VBA macro in an Access database, which also stored the samples.
