Which muscle grade indicates a full range of motion against gravity?

The correct grade that indicates a full range of motion against gravity is associated with the term "Normal." When assessing muscle strength and function, a "Normal" grade signifies that a muscle can complete its full range of motion against gravity with maximal resistance.

In practical terms, this means that the muscle is functioning optimally, showing both strength and endurance in performing movements independently without assistance. This is essential when evaluating the degree of muscle performance and its impact on physical activity. Overall, a "Normal" grade confirms that the muscle not only has the capacity to move through its range but can also do so effectively under standard testing conditions.
