Design outcomes

Primary

MeasureTime frame
Expected result 1: Stress response by the relative frequency of alpha and beta waves as measured by the electroencephalography at F3 and F4, immediately, 15 min and 30 min after stress stimulation. ;Expected result 2: Stress response by the Galvanic Skin Response measured in micro-Siemens, immediately, 15 min and 30 min after stress stimulation. ;Expected result 3: Stress response by the changes in respiratory frequency measured breaths per minute, immediately, 15 min and 30 min after stress stimulation. ;Expected result 4: Changes in peripheral sensory function as measured by the threshold (micro-Amperes) and response time (milliseconds) to electric stimuli applied to the skin, 15 min and 30 min after stress stimulation.—

Secondary

MeasureTime frame
Expected result 5: Perception of anxiety as measured by the STAI questionnaire at baseline (before stress stimulation).—
