Physiological Impact of Vibro-Acoustic Therapy on Stress and Emotions through Wearable Sensors
2018
Stress represents one of the dominant factors of young adults’ health, negatively affecting emotional, mental and physical aspects. There are several works in the literature aimed at detecting stress levels and conditions through the use of wearable devices. In this paper we investigated the effects of vibro-acoustic therapy (VAT) on physiological signals in a small group of young adults, trying to detect its positive effect on their stress condition. VAT has its origin in 1980s with basic instruments able to transmit music and vibrations. Here, we exploited AcusticA, an innovative VAT solution represented by a wooden chaise longue developed by following the principles of a big soundboard, and thus implementing a whole-body approach. Therapeutic sessions are accompanied by selected relaxing melodies, appropriately composed by a music therapist. We recruited 8 volunteer subjects, working in the same environment and characterised by similar stress conditions. We analysed the main components of ECG and GSR signals in order to highlight physiological responses and their variations between a rest baseline phase and a 20 minute therapy. Results show a general decreasing trend in HR, SCRs and their amplitude, confirming the relaxing component of the therapy.
