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

OBJECTIVE

To evaluate a group-based music intervention in patients with Parkinson's disease.

DESIGN

Parallel group randomized controlled trial with qualitative triangulation.

SETTING

Neurorehabilitation in primary care.

SUBJECTS

Forty-six patients with Parkinson's disease were randomized into intervention group ( = 26), which received training with the music-based intervention, and control group ( = 20) without training.

INTERVENTIONS

The intervention was delivered twice weekly for 12 weeks.

MAIN MEASURES

Primary outcome was Timed-Up-and-Go subtracting serial 7's (dual-task ability). Secondary outcomes were cognition, balance, concerns about falling, freezing of gait, and quality of life. All outcomes were evaluated at baseline, post-intervention, and three months post-intervention. Focus groups and individual interviews were conducted with the intervention group and with the delivering physiotherapists.

RESULTS

No between-group differences were observed for dual-task ability. Between-group differences were observed for Falls Efficacy Scale (mean difference (MD) = 6.5 points; 95% confidence interval (CI) = 3.0 to 10.0,  = 0.001) and for Parkinson Disease Questionnaire-39 items (MD = 8.3; 95% CI = 2.7 to 13.8,  = 0.005) when compared to the control group post-intervention, but these were not maintained at three months post-intervention. Three themes were derived from the interviews: , and .

CONCLUSION

Patient-reported outcomes and interviews suggest that the group-based music intervention adds value to mood, alertness, and quality of life in patients with Parkinson's disease. The study does not support the efficacy in producing immediate or lasting gains in dual-tasking, cognition, balance, or freezing of gait.
