Which of the following is an example of a functional mobility task?

Functional mobility tasks are activities that involve moving from one position to another, which are essential for daily living and maintaining independence. The task of transitioning from sitting to standing directly reflects this definition, as it requires coordination, strength, and balance to successfully move from a seated position to an upright stance. This type of movement is critical for performing everyday activities, such as getting out of bed, moving around the house, or participating in social settings.

In contrast, the other options involve cognitive or fine motor skills rather than mobility. Calculating mathematical equations is purely a cognitive exercise, involving mental processes without any physical movement. Completing written assignments and typing on a computer, while they do require certain physical skills, primarily involve fine motor control and hand-eye coordination, not larger functional mobility movements that are crucial for mobility tasks.
