If a client can flex her elbow fully when gravity is eliminated, the expected grade is indeed a score of 2 out of 5. This score is given in manual muscle testing when a muscle demonstrates the ability to perform a movement through its full range of motion without the resistance of gravity.

In the context of manual muscle testing, a 2 out of 5 indicates that the muscle can move through the entire range of motion when there is no gravitational force acting against it, meaning the client can perform the desired movement, but cannot do so against gravity. This is a crucial distinction because it indicates that there is some degree of muscle function, albeit not sufficient to overcome gravity, which would be necessary for a higher grade.

Understanding this grading system highlights the importance of testing muscle strength in various conditions and provides a framework for rehabilitation and treatment planning.
