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.
