Key Takeaway
Vibroacoustic Sound Massage increased parasympathetic activity (measured via ECG) and improved relaxation markers (EEG) while reducing perceived stress scores.
Summary
This controlled trial examined the effects of vibroacoustic stimulation on stress markers using both physiological and psychological measures.
Results showed that vibroacoustic therapy shifted participants toward parasympathetic dominance, improved EEG relaxation markers, and reduced subjective stress, supporting its use for nervous system regulation.
Methods
- Controlled trial design
- 24 participants
- Single session intervention
- ECG for autonomic assessment
- EEG for brain state monitoring
- PSS-10 for perceived stress
Key Results
- Increased parasympathetic activity (ECG)
- Improved EEG relaxation markers
- Reduced concentration/arousal
- Improved PSS-10 stress scores
