Task performance in the ON and OFF therapy state for ODT and ODT + DBS patients.
| Task | Therapy state | ODT | ODT + DBS | ||
|---|---|---|---|---|---|
| N | Mean ± SD | N | Mean ± SD | ||
| DTTa | ON | 7 | 82.42 ± 16.89 | 9 | 89.74 ± 12.16 |
| OFF | 7 | 77.47 ± 13.22 | 9 | 89.32 ± 13.43 | |
| TASIT | ON | 6 | 72.02 ± 7.30b | 9 | 71.43 ± 13.60 |
| OFF | 4 | 74.11 ± 10.26 | 9 | 71.03 ± 15.09 | |
| RMET | ON | 6 | 67.13 ± 6.90 | 8 | 63.22 ± 12.93c |
| OFF | 6 | 70.37 ± 5.46 | 7 | 65.62 ± 21.18 | |
| MAV | ON | 7 | 62.22 ± 8.19 | 9 | 59.38 ± 9.38 |
| OFF | 7 | 63.49 ± 6.92 | 9 | 59.63 ± 10.57 | |
Means shown are % accuracy ± SD. N = Number of subjects per condition and task. ap < 0.05 for effect of therapy state. For within-subjects analyses comparing ON/OFF performance, patients with data available from only one testing session were not included. For bTASIT, two ODT patients were excluded from within-subject analysis for this reason and the adjusted mean ± SD for the remaining four subjects in the ON therapy state is 69.64 ± 6.84, and for cRMET, one ODT + DBS patient was excluded and the adjusted mean ± SD for the remaining seven subjects in the ON therapy state is 66.25 ± 10.46.
