EDOR® THE METHOD

The traditional method to identify suicide risk is based on oral conversations between caregivers and depressed patients and on statistical features of the patient and history of suicide attempts. Experiences show how difficult it is to find the risk patients with such approaches.

Emotra’s method, EDOR®, is an objective and quantitative test, for the purpose of identifying hyporeactive persons. Results from clinical studies have shown that, as many as 97 per cent of the studied patients who have committed suicide were hyporeactive. This represents an undisputable strong relationship between hyporeactivity and risk for suicide.

 

BRIEF DESCRIPTION

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
  • The use of EDOR® makes it possible to support the caregivers in avoiding overtreatment (unnecessary preventive actions) of patients, that do not belong to the risk group
  • The number of referrals from the general hospital care to the psychiatric specialist care, may be reduced significantly
