Emotras technique, EDOR (ElectroDermal Orientation Reactivity), is a psychophysiological test, which has been developed from many years of research work in experimental psychiatry by doctor Lars-Håkan Thorell, at the Linköping University.
The diagnostic method, EDOR, is used to test depressed patients and measures the tested person’s reactivity, or rather responses to a series of sound signals. The normal behaviour is to react instantaneous to the first signal, the Orientation reaction and then learn that these signals are of no importance. As a consequence the response to the signals, which follows after the first one, will be reduced.
This is in contrast to how hyporeactive patients react. Instead their responses disappear almost immediately after the first signal and in some cases they do not even react to that.
In reality the reactions are measured, as momentary electrical current amplitudes, resulting from immediate and short pulses of transpiration. The optimal way to measure this electrical current is by establishing an electrical circuit with the help of a weak source of 0,5 V, two fingers and a pair of gold electrodes attached to a specially designed electronic device, EDOR Box.
Benefits from the use of EDOR:
- A solution to a key problem within the psychiatric care, for which there so far has been no accurate alternative
- Many lives can bee saved if risk patients may be identified at an early stage
- If most suicide attempts can be prevented, high costs for hospital care and rehabilitation can be avoided
