Targeting Cognition and Behavior Post-Stroke: Combined Emotional Music Stimulation and Virtual Attention Training in...

Area of Science:

• Neurorehabilitation
• Psychology
• Cardiology

Background:

• Emotionally salient music may enhance attention-based rehabilitation.
• Concurrent music and virtual reality (VR) programs for chronic stroke are understudied.
• Personalized emotional music stimulation (EMS) combined with VR rehabilitation system (VRRS) was evaluated.

Purpose of the Study:

• To assess if EMS layered onto VRRS augments cognitive, affective, physiological, and functional outcomes in chronic stroke survivors.
• To compare outcomes between VRRS alone and VRRS+EMS interventions.
• To investigate correlations between physiological changes and psychological improvements.

Main Methods:

• A quasi-randomized outpatient trial involving 20 adults post-ischemic stroke.
• Intervention groups: VRRS alone (control, n=10) and VRRS+EMS (experimental, n=10).
• Both groups underwent 8 weeks of 3x/week VRRS cognitive training; EMS group had additional music sessions. Primary outcomes: cognition and global function; secondary: motivation, depression, anxiety, heart rate.

Main Results:

• The VRRS+EMS group showed significant improvements across all measured domains: cognition, motivation, depression, anxiety, heart rate, and disability, with large effect sizes.
• The control group (VRRS alone) exhibited modest gains in cognition and motivation, and a slight heart rate reduction, but no significant mood or disability changes.
• Post-treatment, the music group outperformed controls in cognition, motivation, and disability. Change-score analyses favored the music intervention for all endpoints.

Conclusions:

• Integrating personalized emotional music into VR attention training yields substantial and clinically meaningful improvements in stroke survivors.
• The combined VRRS+EMS approach enhances cognition, mood, motivation, autonomic regulation, and functional independence.
• This study demonstrates the synergistic effect of combining auditory emotional stimuli with immersive virtual reality for neurorehabilitation.
