Skin conductance
Different methods have been used to evaluate the stress response
from pain stimuli and injury in the nervous system.
We have developed a software program to
analyse spontaneous and stimulated skin conductance that is very
easy to use. The apparatus we use to measure skin conductance is
very sensitive. This technology is therefore preferred to others.
Heart rate and heart rate variability analyses are developed to
be measured at the same time as skin conductance activity if
wanted. |

THE PRINCIPLES OF THE METHOD THAT MEASURES EMOTIONAL SWEATING
When the sympathetic nervous system activates the sweat glands,
the sweat channels are filled up and the conductance in the skin
increases before the sweat evaporate and the skin conductance
decreases. During this procedure a wave will occur in our
measurement. By increased activity in this part of the
sympathetic nervous system, an increase in the number and
amplitude of the waves and an increase in the mean skin
conductance level occur. |
