What term is used to describe the downward movement of the foot away from the tibia?

The term that describes the downward movement of the foot away from the tibia is plantarflexion. This motion occurs when the angle between the foot and the front of the leg increases, allowing the toes to point downwards. It is the opposite of dorsiflexion, where the foot is raised towards the shin.

Plantarflexion is crucial for various physical activities, such as walking, running, and jumping, as it helps propel the body forward. It involves the engagement of the calf muscles, specifically the gastrocnemius and soleus.

Understanding the biomechanics of the foot and ankle is essential for those fitting therapeutic shoes, as proper alignment and movement can greatly affect comfort and mobility for individuals with foot-related issues.
