Psychophysiological Stress Test

One assessment tool in biofeedback is a psychophysiological stress profile which is often done in order to identify the reactions of all different bodily functions on physical, emotional or cognitive stressors. When a stimulus is presented the sympathetic nervous system gets activated. During relaxation, the bodily signals change as influenced by the parasympathetic nervous system. The evaluation of the stress profile provides indication view of the physiological parameters that are out of balance and can be addressed for training. There are many ways to conduct a stress profile by offering different cognitive, emotional or maybe even looking at physical stressors. Use, build in stroop test, math test or individual stressors through pictures, videos, audio or verbal instructions.

How is it measured?

During the stress test the common physiological “stress” parameters are measured like muscle tension, skin conductance, temperature, respiration and heart rate. Use the NeXus-10 or NeXus-32 for a full stress profile. Both allow for simultaneous measurement of EEG and with the NeXus-32 even qEEG.
