Brief Summary:
The purpose of this study is to characterize the surface electrical potential of acupuncture points with a Scanning Kelvin Probe.

Condition or disease Intervention/treatment
Healthy Individuals Acupuncture Points Electrical Potential Other: not applicable in this study

Detailed Description:
Acupuncture points are anatomical structures described by traditional Chinese medicine. To this day, however, their scientific and Western anatomical characterizations remain unclear. Past studies have suggested that acupuncture points are distinct electrically (increased electrical conductivity). To evaluate this claim, this study uses a Scanning Kelvin Probe to study the electrical potential of three acupuncture points and their respective adjacent controls in 24 healthy individuals. The Scanning Kelvin Probe is a novel device that measures the electrical potential of skin without actually touching the skin surface.
