How are the MRC-SS scores calculated across sides?

• A. Scores are averaged across sides.
• B. Scores are taken separately for each side, then summed.
• C. Scores are added across both sides without regard to sides.
• D. Scores are taken separately for each side, then combined to yield the total score.

Answer: (D)

The scores are built by evaluating six key muscle groups on each side, rating each on a 0–5 scale, and then adding all twelve scores together to form the total. This means you assess one side, assess the other side, and then combine those per-side results to yield a single overall MRC-SS. This approach preserves information about any weakness on either side while giving a single global value (0–60) to track overall muscle strength and progress.
