Log rolling spinal pt's

Good afternoon everyone. I am an ICU RN in a large referral community on modified work due to an out of hosp injury. Management have we working with an educator, as a "research assistant". They currently have me researching best practise guidlines on how to effectively log-roll technique,procedure etc...does anyone know of any articles that they mey have come across or studies done on how to log-roll, aswell if the article happens to apply to spinal injury that is fine as this is the pt population that it is directed for. There is very little data out there, all the info that I have found is scarce. The one thing I have come across many policies from different hospitals, however there are no bibliographies with them...thank-you for your time...
