What does MRC-SS assess?

What does MRC-SS assess?

• A. Tests for Critical-Illness Acquired Weakness (CAW)
• B. Measures respiratory rate only
• C. Diagnoses CIM via imaging
• D. Evaluates liver function

Answer: (A)

The main idea is identifying ICU-acquired weakness by a bedside muscle strength test. The MRC sum-score measures strength across six bilateral muscle groups (rating each from 0 to 5), giving a total out of 60. It’s used to detect Critical-Illness Acquired Weakness, reflecting weakness that develops during a critical illness and can persist into rehabilitation. It’s not a measure of breathing rate, it doesn’t diagnose CIM through imaging, and it doesn’t assess liver function. A lower score indicates greater weakness and helps guide therapy and prognosis.
