Table 4.
Performance measures of thalamotomy patients and thalamotomy control subjects
| Performance measure | Thalamotomy patients | Thalamotomy controls | Change from controls (%) | All ET patients | All controls | Change from controls (%) |
|---|---|---|---|---|---|---|
| Group size | 5 | 7 | — | 24 | 26 | — |
| Peak speed (m/s) | 0.26 (0.04) | 0.34 (0.06) | −23.4** (−23.8**) | 0.28 (0.05) | 0.32 (0.05) | −12** (10) |
| Path length (cm) | 10.43 (1.40) | 10.49 (1.13) | −0.5 (22.7) | 10.65 (1.35) | 10.18 (0.82) | 5** (65***) |
| Movement duration (s) | 1.52 (0.36) | 1.23 (0.22) | 24.1* (65.0) | 1.54 (0.34) | 1.14 (0.18) | 35***** (85***) |
| ae at 300 ms (°) | 0.23 (6.14) | −0.08 (5.18) | −388 (12.9) | 0.52 (6.70) | −0.15 (4.64) | −441 (44*****) |
| Arm compliance (°) | 16.83 | 16.66 | 1.0 | 16.61 | 15.59 | 7 |
Note: This table follows the same convention as Table 2. All ET patients—combining DBS and thalamotomy patients; all controls—combining the respective control subject groups.
