Amplifying walking activity in Parkinson's disease through autonomous music-based rhythmic auditory stimulation:...

Area of Science:

• Neurorehabilitation
• Movement Disorders
• Digital Health Interventions

Background:

• Moderate-intensity walking offers disease-modifying benefits for Parkinson's disease (PD).
• A gap exists in sustainable gait interventions for PD that enhance walking intensity, duration, and quality.
• Current PD rehabilitation lacks effective, real-world walking strategies.

Purpose of the Study:

• To evaluate the effectiveness of an autonomous music-based digital rhythmic auditory stimulation (RAS) system as a gait intervention for individuals with PD.
• To compare the effects of RAS-enhanced walking with traditional brisk walking on gait parameters and habit formation.
• To determine if RAS can improve walking intensity, daily step count, and gait variability in PD.

Main Methods:

• A randomized controlled trial (NCT05421624) was conducted with two arms: an experimental arm using an autonomous RAS system and an active-control arm with brisk walking.
• Participants engaged in real-world walking interventions over a specified period.
• Gait parameters, including intensity, daily steps, and gait variability, were measured and compared between the groups.

Main Results:

• The autonomous RAS system significantly amplified moderate-to-vigorous walking intensities compared to brisk walking.
• Participants using the RAS system showed an increase in daily steps.
• RAS intervention led to improved (reduced) gait variability, indicating better gait stability.
• While both interventions fostered walking habits, only RAS demonstrated strengthened habits alongside improved gait outcomes.

Conclusions:

• An autonomous, music-based RAS system is an effective and translatable gait intervention for individuals with Parkinson's disease.
• RAS enhances key walking metrics (intensity, steps, variability) and promotes habit formation, addressing a critical need in PD rehabilitation.
• This personalized digital health approach offers a promising, sustainable solution for improving real-world walking in PD.
