In Vivo Biomechanical Measurements of a Football Player's C6 Spine Fracture.

The article discusses research which focused on the occurrence of cervical spine fracture in a male athlete who has performed a head-down tackling maneuver. The researchers captured and examined in vivo biomechanical data gathered from the patient by measuring peak linear and rotational acceleration of the head with the use of the Gadd Severity Index (GSI). They quantified the impact magnitude of the maneuver through the use of the Head Injury Criteria (HIC).
