Means and 95% confidence intervals of peak manipulation 3D excursion angles depending on extrication manipulations and cervical collar use. Left: Peak manipulation 3D excursion angles’ means recorded when using a cervical collar (all terrains included); Right: Peak manipulation 3D excursion angles’ means recorded when using manual in-line stabilization (all terrains included). (a) Winter clothes removal, (b) cervical collar installation, (c) logroll to lateral decubitus, (d) logroll back to supine, (e) move to vacuum mattress midline, (f) immobilization on the vacuum mattress, (g) transfer to toboggan. •: flat area, □: steep slope, Peak 3D θM: peak manipulation 3D excursion angle
