Extrication studied: Self-extrication and collar application
In this study total movement as well as maximal movements are considered.

Representation of maximal movements which are captured and reported in current biomechanical models of spinal movement vs non-maximal movememts that are not

new metric to describe these movements “travel” is presented:

Maximal movement and travel

Findings
AP travel at cervical spine (MM)
