ICU Mobility Scores

Ann, PT posts: 

DEAR ERI COMMUNITY: How are people documenting mobility in the ICU? Has anyone used the Perme ICU Mobility Score? I heard it is now being tested for validity and inter-observer reliability, and Chris Perme is presenting it at the 2014 CSM of APTA. 

Are there other ways you document mobility in the ICU?

Thanks! Ann
