Comparison of slopes of linear relationship of vertical and torsional drift velocities and horizontal head eccentricities under different conditions in healthy individuals
| Experimental condition | Vertical velocity slope (s−1) | Torsional velocity slope (s−1) |
|---|---|---|
| LED target plus laser | 0.0003 ± 0.002 | −0.001 ± 0.006 |
| LED target only | 0.0002 ± 0.0007 | 0.0006 ± 0.0001 |
| LED target and neck vibration | 0.002 ± 0.003 | 0.001 ± 0.001 |
| LED target, laser, and neck vibration | −0.003 ± 0.008 | 0.008 ± 0.007 |
Data for amplitudes are not shown because they were nil.
