Traumatic brain injury (TBI) and stroke are leading causes of mortality and long-term disability worldwide, necessitating innovative rehabilitation strategies. This review synthesizes current research on the therapeutic effects of music, healing frequencies, and binaural beats in enhancing recovery outcomes for TBI and stroke patients. Music therapy has been shown to improve motor function, cognitive recovery, and emotional well-being through mechanisms such as rhythmic auditory stimulation, neuroplasticity facilitation, and emotional engagement. Healing frequencies, including 432 Hz and 528 Hz, are reported to reduce inflammation, promote cellular repair, and improve neuroplasticity. Binaural beats have demonstrated the potential to modulate brainwave activity, enhance relaxation, and support cognitive and emotional rehabilitation. Physiological mechanisms include the activation of sensorimotor pathways, synchronization of neural networks, and the release of neurotrophic factors. While existing evidence highlights the significant promise of these interventions, challenges such as methodological variability and limited large-scale studies underscore the need for further research. The integration of auditory therapies into multimodal rehabilitation protocols offers a cost-effective and patient-centered approach to improving recovery outcomes and quality of life for individuals affected by TBI and stroke.
