Question: 1 / 400

What grade of muscle strength corresponds to full range of motion against gravity with full resistance?

Grade 2

Grade 3

Grade 4

Grade 5

Muscle strength grading is a systematic way to assess an individual's ability to move a joint against resistance. In this context, a grade of muscle strength that corresponds to full range of motion against gravity with full resistance is classified as grade 5. This level of strength indicates that the muscle can not only perform the movement throughout its complete range but can do so while overcoming maximum resistance, demonstrating optimal strength.

In contrast, lower grades indicate varying degrees of weakness or limitation in movement. For instance, grade 3 would indicate movement through a full range against gravity but without added resistance, while grade 4 would show movement against gravity with some level of resistance but not the maximum. These distinctions illustrate the decline in strength and capacity as the grade decreases, making grade 5 the highest and indicating adequate muscular health and function.
