What does MRC-SS stand for?

• A. Medical Research Council Scale for Strength
• B. Muscle Response and Conduction Score
• C. Medical Research Council Sum Score
• D. Myocardial Response and Circulation Scale

Answer: (C)

The main idea is that MRC-SS is the Medical Research Council Sum Score, a single number that quantifies overall muscle strength. You assess each of 12 muscle groups (six movements: shoulder abduction, elbow flexion, wrist extension, hip flexion, knee extension, and ankle dorsiflexion) on both sides, using the standard MRC scale that runs from 0 to 5 for each muscle. Adding all 12 scores gives a total from 0 to 60. This summed score provides a global measure of strength and is widely used in ICU settings to detect and monitor ICU-acquired weakness; a lower total indicates greater weakness, with common research and clinical benchmarks noting that scores below about 48 reflect significant weakness. The other options aren’t the standard name for this composite measure: they either refer to the per-muscle scale or to nonstandard terms, so they don’t capture the same summed metric.
