Evaluation of Stress Levels by Monitoring Trapezius Muscle Activity using EMG & EDA

Stress is a common leading factor for both physical and mental issues among students and professionals due to different tasks and lifestyle. The upper trapezius muscle reacts strongly to stress, making it ideal for
surface EMG recording[4]. Electrodermal activity (EDA) reflects changes in skin conductance and resistance controlled by the autonomic nervous system. The EMG and EDA are recorded during the performance of tasks which involves physiological, psychological, visual and problem solving.
The features extracted from the recorded EMG signal and the parameters of EDA helps in analysing the response of stress in the body. This helps to develop non-invasive, real-time stress monitoring tools for health and ergonomic use.
