Computerized Mental Arithmetic Task Based Human Stress Level Detection Using Physiological Signal

The objective of this study is to induce and measure the human stress level through computerized mental arithmetic task and multiple physiological signals (ECG, EMG, GSR, and skin temperature). Studies suggested that mental arithmetic task is one of the efficient stimuli to induce the stress. Hence, this mental arithmetic task protocol has been improved in to computerized version. The protocol will be tested with normal subjects and multiple physiological signals will be acquired simultaneously. The questionnaire about the subject experience will be obtained in order to strengthen the stress induction. The normal volunteer subjects will be invited for the participation this study. The physiological signal will be analyzed using suitable algorithm based on the characteristics of each signals. The multiple signal based stress level assessment system will be developed by training and testing the acquired data.

Primary Outcome Measures:
  • Stress levels assesment desinged based on the physiological signal acquired from the various subject by using MAT protocal. [ Time Frame: 90 minutes ]

    Selection of physiological signals

    The following four physiological signal will be acquired based on the strong clinical evidence, Non-intrusive measurement, and futuristic to develop the real time detection system using compact electronics that to reduce the obtrusive of the human in real time activities such as in job, sports application.

    Electromyogram Galvanic skin response Skin temperature

Estimated Enrollment: 300
Study Start Date: October 2011
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: stress inducing task
Normal subjects without history medication presently will be participated. Stress induced through stress inducing task (mental arithmetic task), the physiological signals collected before and during the task simultaneously. All the subjects will be participating only once in this MAT based study. Because, the stress will not be possible to induce when the subject is more familiar with the stress inducing task.
Other: physiological signals
