A pilot study on skin potential recordings as a measure of nociception in pain-free dogs and humans, and in dogs with persistent pain

The Pain Trace™ device can detect changes in the skin's electrical potentials claimed to be associated with pain related alterations in the sympathetic and parasympathetic nervous system activity. Positive voltages represent the absence of major pain, whereas negative voltages represent moderat...

Positive voltages represent the absence of major pain, whereas negative voltages represent moderate to severe pain.

In study Part 1 baseline skin potentials were recorded in healthy dogs and compared to readings obtained in human volunteers. In dogs, data were recorded with electrodes placed at three separate sites: neck, axilla, and thorax. In humans, data were collected from the palms.
