Rear impact testing revealed that higher velocities significantly increase cervical spine motion, particularly at lower levels (C5-C6 and C6-C7). This research clarifies head-neck kinematics during whiplash injury events.

Area of Science:

  • Biomechanics
  • Spinal cord injury research
  • Injury biomechanics

Background:

  • Rear impact loading of the cervical spine presents complex biomechanical challenges.
  • Previous studies have not fully detailed how cervical spine kinematics change with impact velocity and spinal level.

Purpose of the Study:

  • To investigate the relationship between cervical spine segmental motion and rear impact velocity.
  • To identify specific cervical levels most affected by varying impact speeds.

Main Methods:

  • Utilized 10 isolated human head-neck specimens for experimental testing.
  • Measured segmental motion across cervical levels C2-C3 to C6-C7.
  • Applied rear impact velocities of 2.1, 4.6, 6.6, and 9.3 km/h.

Main Results:

  • Segmental motion increased with higher input velocities across all tested levels.
  • Levels C5-C6 and C6-C7 exhibited a greater increase in segmental motion magnitude compared to other levels at higher velocities.

Conclusions:

  • Cervical spine kinematics during rear impact are velocity-dependent.
  • Lower cervical spine segments (C5-C6, C6-C7) are more susceptible to increased motion at higher impact velocities, informing whiplash injury mechanisms.
