Which assessment includes Endurance as a category?

• A. FSS-ICU
• B. CPAx
• C. Perme ICU Mobility Score
• D. PFI-s

Answer: (C)

Endurance as a separate domain is a key feature for guiding how far and how fast to push mobilization in the ICU. The Perme ICU Mobility Score was developed to quickly rate multiple aspects of a patient’s mobility potential, and one of its items specifically measures endurance — how long a patient can sustain activity before fatigue or signs of intolerance limit progress. This focus on tolerance and sustained effort helps clinicians decide when to advance activities, increase intensity, or scale back for safety.

The other assessments mainly concentrate on whether specific tasks can be completed (like bed mobility, transfers, or gait) or on overall functional ratings, without a distinct endurance category. That’s why endurance isn’t a labeled domain in those tools. So, for explicitly assessing endurance in ICU mobilization, the Perme ICU Mobility Score is the best fit.
