Which scale is used to evaluate muscle strength in LTCH?

• A. Barthel Index
• B. MRC-SS
• C. PFIT
• D. FSS-ICU

Answer: (B)

Muscle strength is measured with a direct, standardized bedside test that sums up force across several key muscle groups. The Medical Research Council sum-score does this by testing six muscle groups in each limb (shoulder abduction, elbow flexion, wrist extension, hip flexion, knee extension, and ankle dorsiflexion). Each muscle group is graded from 0 to 5, giving a total possible score of 60. A higher total reflects stronger overall strength, and tracking the score over time shows gains or declines in strength. This direct strength measure is why it’s commonly used in LTCH settings to quantify and monitor weakness. Other scales, like the Barthel Index, assess independence in daily activities, not raw strength. PFIT and FSS-ICU evaluate functional performance and endurance in ICU patients, and while strength influences those measures, they don’t provide a pure strength score.
