Which components are included in the supination of the foot-ankle complex?

Supination of the foot-ankle complex involves a specific combination of movements that orient the foot to function effectively, especially during activities such as walking or running. The correct combination of movements in supination is characterized by inversion of the hindfoot, adduction of the forefoot, and plantarflexion of the ankle.

Inversion of the hindfoot raises the medial side of the foot, resulting in a more concave shape on the plantar surface, which aids in maintaining stability and adaptability to varying surfaces. Adduction of the forefoot brings it closer to the midline of the body, which contributes to the overall alignment and stability of the foot when in a supinated position. Meanwhile, plantarflexion of the ankle points the toes downward, which is essential for effective propulsion and motion during ambulation.

This set of movements, when combined, allows the foot to adapt to different terrains and manage forces effectively during phases of gait, particularly in push-off phases. By understanding these movements, one can apply proper orthotic interventions or evaluate gait biomechanics with greater accuracy.
