What is the Grading Scale Used in Muscle Strength Testing?
The most commonly used grading scale is the Medical Research Council (MRC) scale: - Grade 0: No muscle contraction. - Grade 1: Flicker or trace of contraction. - Grade 2: Active movement with gravity eliminated. - Grade 3: Active movement against gravity. - Grade 4: Active movement against gravity and some resistance. - Grade 5: Normal muscle strength.
