How much is the normal range of eversion at the ankle?

The normal range of eversion at the ankle is typically around 5 degrees. Eversion involves the movement of the foot that tilts the sole outward, away from the midline of the body. The range of motion for eversion is considerably less than that for inversion, which is the movement that tilts the sole inward toward the midline.

This limited range is due to the anatomical structure of the ankle and foot, including the interactions between the talus and surrounding bones, ligaments, and tendons that restrict more extensive movement. As a result, a 5-degree range for eversion is widely accepted in clinical assessments and functional movement evaluations. Knowledge of this normal range helps athletic trainers and therapists identify abnormal movement patterns that could indicate injury or dysfunction.
