Group-based music intervention in Parkinson's disease - findings from a mixed-methods study

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Music Therapy

Background:

• Parkinson's disease (PD) is a progressive neurodegenerative disorder affecting motor control.
• Non-pharmacological interventions are crucial for managing PD symptoms and improving quality of life.
• Music-based interventions show potential in addressing various aspects of PD.

Purpose of the Study:

• To evaluate the effectiveness of a group-based music intervention for patients with Parkinson's disease.
• To assess the impact of music intervention on dual-task ability, cognition, balance, falls efficacy, and quality of life.

Main Methods:

• A parallel-group randomized controlled trial with qualitative triangulation was conducted.
• Forty-six patients with PD were randomized into a music intervention group or a control group.
• Intervention involved 12 weeks of twice-weekly music training; outcomes were assessed at baseline, post-intervention, and 3-month follow-up.

Main Results:

• No significant differences were found in dual-task ability between groups.
• The music intervention group showed significant improvements in falls efficacy and quality of life immediately post-intervention, but these were not sustained at 3 months.
• Qualitative data revealed themes related to expectations, treatment content, and success factors.

Conclusions:

• Group-based music interventions may positively impact mood, alertness, and quality of life in Parkinson's disease patients.
• The intervention did not demonstrate efficacy in improving dual-tasking, cognition, balance, or freezing of gait.
• Patient-reported outcomes and qualitative feedback suggest perceived benefits beyond objective measures.
