Physiologic responses to acupuncture point stimulation: a pilot study to evaluate methods and instrumentation
1Biomedical Signal Processing Laboratory, Electrical and Computer Engineering, Portland State University, Portland OR, USA.
Abstract:
The physiological responses to needle stimulation of an acupuncture point and a nearby control point were compared in six healthy participants. The electrocardiogram (ECG), respiration, and electrodermal response (EDR) were measured along with the times of needle insertion, interim needle stimulation and needle removal. In addition to the aforementioned, any relevant events such as movement of the subject, unexpected noise, etc were annotated.
