Group therapeutic singing improves clinical motor scores in persons with Parkinson's disease.

Background: Previous reports suggest that group therapeutic singing (GTS) may have a positive effect on motor symptoms in persons with Parkinson's disease (PD).

Objective: To determine the effect of a single session of GTS on clinical motor symptoms.

Methods: Clinical motor symptom assessment was completed immediately before and after 1 hour of GTS in 18 participants.

Results: A significant decrease in average scores for gait and posture and tremor, but not speech and facial expression or bradykinesia was revealed.

Conclusion: These results support the notion that GTS is a beneficial adjuvant therapy for persons with PD that warrants further research.
