Group-averaged characteristics of quiescence
| Spinal Level | Onset of Quiescence (ms) | Duration of Quiescence (ms) | Normalized Time of Onset (% RR) | Normalized Duration of Quiescence (% RR) | Absolute Quiescent Velocity (mm/s) | Maximum Absolute Velocity (m/s) |
|---|---|---|---|---|---|---|
| Medulla | 158 ± 10 | 448 ± 96 | 20 ± 2 | 56 ± 7 | 0.3 ± 0.2 | 1.9 ± 0.5 |
| C2 | 266 ± 110 | 360 ± 113 | 33 ± 15 | 45 ± 20 | 0.3 ± 0.2 | 4.3 ± 1.3 |
| C6 | 314 ± 105 | 286 ± 96 | 39 ± 13 | 36 ± 12 | 0.4 ± 0.1 | 5.2 ± 0.7 |
Note:—Cord velocity is <0.06 cm/s (in cervical spinal cord motion). RR indicates a period in the cardiac cycle.
