Development of a Pain Measurement Device Using Electrical Stimulation and Pressure: A Pilot Study

Figure 2

Method of pain evaluation measurements in animal model, using the pain measurement system. (a) The rat was attached to a bipolar electrode on the right flank side. (b) The current-voltage plot for measurement of skin resistance according to a gradually increasing pulsed voltage. (c) Rat was restrained for 1~2 min in a rat restrainer for pressure stimulation on carrageenan-induced paw edema.
