What does "dorsiflexion" specifically involve?

Dorsiflexion specifically involves the movement where the ball of the foot is brought closer to the shin. This action occurs at the ankle joint and is essential for activities such as walking, running, and climbing stairs, as it helps in lifting the foot to clear the ground during the swing phase of gait. When the toes point upward towards the dorsal aspect of the foot, it allows for better control and positioning of the foot to facilitate smooth movement and balance. Understanding dorsiflexion is important for assessing mobility and strength in the lower extremities, especially during functional movements.
