Descriptive statistics for severity of motor complications of therapy (MDS‐UPDRS‐IV) items (n = 154)
| Variable (unit; scale range) | Total sample mean (SD) | Anxiety NOS mean (SD) | DSM anxiety mean (SD) | No anxiety mean (SD) |
|---|---|---|---|---|
| Age (yr) | 68.86 (8.32) | 67.46 (9.60) | 67.14 (8.56) | 68.90 (7.76) |
| Sex (M/F) | 94/60 | 14/14 | 20/22 | 60/24 |
| Time spent with dyskinesias (0–4) | 0.41 (0.88) | 0.93 (1.09) | 0.43 (1.02) | 0.23 (0.65) |
| Functional impact of dyskinesias (0–4) | 0.14 (0.41) | 0.46 (0.64) | 0.19 (0.51) | 0.00 (0.00) |
| Total dyskinesia severity score (0–8) | 0.55 (1.19) | 1.39 (1.64) | 0.62 (1.41) | 0.23 (0.65) |
| Time spent in the “off” state (0–4) | 0.37 (0.59) | 0.64 (0.73) | 0.43 (0.67) | 0.25 (0.46) |
| Functional impact of motor fluctuations (0–4) | 0.31 (0.73) | 0.46 (0.92) | 0.31 (0.64) | 0.26 (0.70) |
| Complexity of motor fluctuations (0–4) | 0.33 (0.66) | 0.64 (0.83) | 0.24 (0.43) | 0.27 (0.67) |
| Total motor fluctuations severity score (0–12) | 1.01 (1.70) | 1.75 (2.12) | 0.98 (1.54) | 0.79 (1.56) |
| Painful “off”‐state dystonia (0–4) | 0.13 (0.47) | 0.11 (0.32) | 0.26 (0.54) | 0.07 (0.46) |
The total dyskinesia severity score is the sum of severity scores for time spent with dyskinesias and the functional impact of dyskinesias. The total motor fluctuations severity score is the sum of severity scores for time spent in the “off” state, functional impact of motor fluctuations, and complexity of motor fluctuations.
