Is dorsiflexion the same as extension?

At the ankle joint, yes, dorsiflexion is technically considered extension. However, for other joints like the wrist, 'extension' is the broader term, and 'dorsiflexion' is a specific type of extension.

Why is it called 'dorsiflexion'?

It comes from Latin 'dorsum' meaning 'back' and 'flectere' meaning 'to bend'. It refers to bending towards the dorsal (top/back) surface of the limb.

In a physiotherapy or physical therapy session, a sports medicine clinic, or an anatomy lecture.

Meaning and Definition

The action of bending or flexing a limb or joint (especially the ankle or wrist) backwards or upwards, decreasing the angle between the body part and its adjacent segment.

In biomechanics and anatomy, dorsiflexion refers specifically to movement that brings the top of the foot (dorsum) towards the shin, or the back of the hand towards the forearm. It is the opposite of plantar flexion (ankle) or palmar flexion (wrist). The term is also applied in physiotherapy and exercise science.
