|---|---|---|---|
| Mobility | 15.1 ± 11.4 | 18.8 ± 11.5 | 0.003 |
| Activities of daily living | 5.9 ± 5.6 | 7.3 ± 5.4 | 0.043 |
| Emotional well-being | 5.8 ± 5.7 | 7.7 ± 6.2 | 0.024 |

| PDQ-39 summary index | 23.5 ± 15.1 | 27.9 ± 14.7 | 0.010 |
Values represent the mean with standard deviation. Analysis was performed by analysis of covariance adjusted for age, sex, disease duration, and UPDRS part III score. QOL: quality of life, PDQ-39: Parkinson’s Disease Questionnaire-39, PD: Parkinson’s disease, UPDRS: Unified Parkinson’s Disease Rating Scale.
