Binaural Beat Music Combined With Rhythmic Photic Stimulation on Depression

Background: Previous studies have suggested that non-pharmacological treatments, such as binaural beat music (BBM) and rhythmic photic stimulation (RPS), may help improve depressive symptoms and enhance quality of life. However, their effectiveness in elderly patients with depression remains unclear. Objectives: This study aims to investigate the effects of combining BBM and RPS on improving depression, quality of life, and heart rate variability (HRV) in elderly patients with depression. Methods: This study was conducted as a single-blind randomized controlled trial. Forty-eight elderly patients with depression were recruited from a long-term care institution in Taiwan and randomly assigned to either the BBM and RPS group or the Sham group. Participants received 20 minutes of intervention daily, Monday to Friday, for 12 consecutive weeks. During the intervention, participants in the BBM and RPS group listened to 10Hz BBM (embedded with classic old songs) and wore RPS glasses that provided 10Hz light stimulation. In contrast, participants in the Sham group listened to classic old songs and wore RPS glasses without the 10Hz light stimulation.
