Study on the effects and mechanisms of rhythmic auditory stimulation on freezing of gait in Parkinson’s disease: investigation based on functional near-infrared spectroscopy (fNIRS) technology
Clinical Report: Investigation of Rhythmic Auditory Stimulation's Impact on FOG
Overview
This study explores the effects of rhythmic auditory stimulation (RAS) on freezing of gait (FOG) in Parkinson's disease using functional near-infrared spectroscopy (fNIRS). Findings indicate that RAS can enhance cortical connectivity and mitigate FOG symptoms, highlighting its potential as a therapeutic intervention.
Background
Freezing of gait (FOG) is a debilitating symptom in Parkinson's disease that significantly increases fall risk and impairs mobility. Understanding effective interventions for FOG is crucial for improving patient outcomes. Rhythmic auditory stimulation (RAS) has emerged as a promising non-invasive treatment option, yet its underlying neurophysiological mechanisms require further investigation.

Key Findings
Individuals with PD + FOG exhibited reduced gait speed and stride length compared to healthy controls.
Neuroimaging revealed decreased activation in the primary somatosensory cortex, premotor cortex, and prefrontal cortex in PD + FOG individuals.
Rhythmic auditory stimuli improved connectivity between the temporal cortex and premotor cortex.
Music therapy enhanced intrinsic connectivity in the prefrontal cortex.
Mental beat imagery may hinder sensorimotor integration due to reliance on internal cognitive processes.
Clinical Implications
The findings suggest that RAS can be effectively integrated into rehabilitation programs for patients with Parkinson's disease experiencing FOG. Clinicians should consider tailoring auditory cueing strategies to individual patient needs to optimize therapeutic outcomes.
Conclusion
This investigation provides valuable insights into the neurophysiological effects of RAS on FOG in Parkinson's disease, supporting its use as a potential therapeutic modality. Further research is warranted to refine these interventions and enhance patient care.
