title: The 6-plus-person lift transfer technique compared with other methods of spine boarding.
abstract: BACKGROUND
  To achieve full spinal immobilization during on-the-field management of an actual or potential spinal injury, rescuers transfer and secure patients to a long spine board. Several techniques can be used to facilitate this patient transfer.
  
  
  OBJECTIVE
  To compare spinal segment motion of cadavers during the execution of the 6-plus-person (6+) lift, lift-and-slide (LS), and logroll (LR) spine-board transfer techniques.
  
  
  METHODS
  Crossover study.
  
  
  METHODS
  Laboratory.
  
  
  METHODS
  Eight medical professionals (1 woman, 7 men) with 5 to 32 years of experience were enlisted to help carry out the transfer techniques. In addition, test conditions were performed on 5 fresh cadavers (3 males, 2 females) with a mean age of 86.2 +/- 11.4 years.
  
  
  METHODS
  Three-dimensional angular and linear motions initially were recorded during execution of transfer techniques, initially using cadavers with intact spines and then after C5-C6 spinal segment destabilization. The mean maximal linear displacement and angular motion obtained and calculated from the 3 trials for each test condition were included in the statistical analysis.
  
  
  RESULTS
  Flexion-extension angular motion, as well as anteroposterior and distraction-compression linear motion, did not vary between the LR and either the 6+ lift or LS. Compared with the execution of the 6+ lift and LS, the execution of the LR generated significantly more axial rotation (P = .008 and .001, respectively), more lateral flexion (P = .005 and .003, respectively), and more medial-lateral translation (P = .003 and .004, respectively).
  
  
  CONCLUSIONS
  A small amount of spinal motion is inevitable when executing spine-board transfer techniques; however, the execution of the 6+ lift or LS appears to minimize the extent of motion generated across a globally unstable spinal segment.
