Real-Time Physiological Signal Feedback for Anxiety Intervention Music System for Postpartum Women

Abstract

Objective: To identify postpartum anxiety in real time and construct a music playback system that can provide music therapy in time, so as to achieve the purpose of better reducing postpartum anxiety. Methods: The real-time emotion algorithm system identified that the maternal anxiety had lasted for 5 minutes through the EDA and BVP signals collected by the wrist wearable device, and then sent random music instructions. After 30 minutes, the music stopped if the patient was not anxious, and continued until the patient was not anxious. The system also takes sleep-wake into account. Experiment: Twenty-six parturients assessed as having present anxiety participated in a 4-week comparative effectiveness trial of music therapy. In the control group (N=13), in addition to routine rehabilitation, music was played twice a day. The study group (N=13) received music therapy through the system in addition to conventional rehabilitation. Anxiety was assessed again after 1 and 4 weeks of intervention. Results: Both groups showed significant anxiety before and after intervention (p<0.05, p<0.01), the study group was more significant, and the performance was more prominent in continuous treatment. Conclusion: The system can identify maternal anxiety in real time and take synchronous and timely treatment, which has a positive effect on reducing postpartum anxiety. The convenience of wrist bracelet can also be applied to other aspects of life.
