Denehy et al reported a modified Physical Function ICU Test (PFIT) to evaluate physical function of a patient in the intensive the care unit (ICU). The authors are from the University of Melbourne, Donvale Rehabilitation Hospital, and Austin Health (Melbourne).
Difference from original 5-item PFIT: removal of bilateral shoulder shrugs (in lifts per minute)
Patient selection: ICU patient on day 5-10 of ICU stay
Parameters:
(1) need for assistance to go from sitting to standing
(2) cadence in steps per minute
(3) shoulder flexion strength using MRC grades from 0 to 5
(4) knee extension strength using MRC grades from 0 to 5

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 12
• The higher the score the better the outcomes.
• A table for converting the score (ordinal scale) to an interval scale is given. The interval value was considered better for tracking.
