Biofeedback Therapy Using Heart Sound to Manage Stress in Young Earthquake Survivors Aged 20 to 25

What this Trial Is About

This research focuses on young earthquake survivors aged 20 to 25 to understand the long-term risk of trauma-induced stress. It evaluates how non-invasive sound therapy affects the vagal nerve by monitoring cardiovascular and neural activity. The study aims to explore biofeedback methods that could help manage stress-related responses in these individuals, considering the psychological and physical impacts of trauma such as wars and natural disasters. Participants will be divided into three groups one group receives no stimulation during mental stress, another undergoes phonocardiographic PCG auditory stimulation, and the third group receives metronome-like stimulation matching the heart rhythm MHR. These interventions are applied during mental stress to assess their effect on stabilizing the autonomic nervous system. The study uses advanced data processing methods like deep learning to analyze biological signals collected during these interventions. During the study, various biological signals will be recorded, including electrocardiography ECG, phonocardiography PCG, electrodermal activity, respiratory rhythm, and near-infrared spectroscopic imaging fNIRS. Participants emotional and psychological states will be evaluated through these signals at baseline and throughout the 2-month study period. Researchers will monitor cardiovascular and neuro-cardiac responses to assess biofeedback effects and stress coping. The total study duration includes baseline measures and follow-up assessments over two months.
