In the context of ankle mobility, what is the range of inversion in degrees?

Inversion of the ankle refers to the movement where the sole of the foot turns inward, toward the midline of the body. The normal anatomical range for ankle inversion is typically recognized to be around 15 to 20 degrees. This range allows for adequate movement during various athletic activities, contributing to balance and the ability to adapt to different surfaces.

Choosing 15 degrees as the correct answer aligns well with the general understanding in the field of athletic training. This measurement is often seen as a functional threshold, enabling athletes to maintain stability and perform effectively in sports. Additionally, this degree of inversion is essential for proper foot mechanics and overall lower extremity function, which is crucial during dynamic movements like cutting, jumping, or changing directions often seen in athletic performance.

Other options such as 5 degrees or lower range values are not clinically representative of standard ankle mobility, while option 50 degrees is excessively beyond normal limits and is not typically attainable in a healthy ankle joint. Hence, identifying 15 degrees as the baseline for inversion highlights an important aspect of evaluating ankle mobility in athletes.
