Understanding Ankle Joint Anatomy

02

Defining Ankle Joint Straightening

The action of 'straightening' the ankle generally refers to moving from a pointed toe position (plantarflexion) to a neutral or flexed position. This movement is termed dorsiflexion.
03

Understanding Dorsiflexion

Dorsiflexion is the action of raising the foot upwards towards the shin, decreasing the angle between the dorsum (top part) of the foot and the leg. This movement occurs at the ankle joint. When the foot is lifted off the ground - as in walking or running - this is an example of dorsiflexion. This movement is important for basic functions like walking and running.
