Participant Flow
3 medical and surgical ICUs at Johns Hopkins Hospitals screened for recruitment from 2008-2009 and 2010-2013 (39 months in total). Recruitment suspended for 17 consecutive months between 2009-2010 due to lack of staffing
2 patients (both randomized to the intervention group) were withdrawn PRIOR to any initiation of intervention due to new data arising after randomization (and before intervention initiation) that indicated the subject met the pre-existing exclusion criteria.

SECONDARY outcome
Timeframe: ICU and hospital discharge and change over timePopulation: This was an a priori subgroup analyses of patients who had mechanical ventilation duration \>=7 days. Not all participants could be evaluated at each time point (e.g. cognitive status) and this explains the different sample sizes for each outcome.
For patients with \>= 7 days of mechanical ventilation, we will compare the 2 groups for the following outcomes: Lower extremity muscle strength, mean change in whole body muscle strength score from baseline to ICU discharge, mean change in whole body muscle strength score from baseline to hospital discharge, and whole body muscle strength score at ICU discharge and at hospital discharge. Each muscle group is assessed bilaterally (scale of 0 \[no visible or noticeable contraction\] to 5 \[maximum strength\]). There are three muscle groups assessed bilaterally for lower extremity (hip flexion, knee extension, and ankle dorsiflexion) (score range 0-30, higher score is better i.e. stronger); while for whole body strength assessment (score range 0-360, higher score is better), the following additional muscles are assessed: shoulder abduction, elbow flexion and wrist extension. The scores are then summed for each patient at each time point.
