Peak Rotational Velocity, Peak Rotational Acceleration, Duration of Unconsciousness, and Rate of Apnea for All Injury Groups (Mean ± SEM)
| Group | n | Peak angular velocity (rad/sec, ± SD) | Peak angular acceleration (krad/sec2, ±SD) | Unconsciousness time (min, ±SEM) | % Apneic |
|---|---|---|---|---|---|
