Ankle sprains are one of the most common injuries that can happen in sports and are quite common in occupational situations. When checking on the ankle, one of the more important assessments has to do with the range of motion of the ankle. If the ankle doesn’t have the proper movement, the possibility of re-injury rises. Agility is needed for much of human movement. It is the ability to change direction efficiently and rapidly. Ankle injuries can lessen agility. The assessment looks at and measures the movement of the ankle in horizontal and longitudinal directions to see how easily the ankle moves. Strength tests may also be conducted to see what other factors are impacting how the ankle is working.
