What movement does inversion specifically describe?

Inversion specifically refers to the movement of the foot where the sole is turned inward toward the midline of the body. This action primarily occurs at the ankle joint and is essential for various activities that require balance and stability, especially during movements such as walking on uneven surfaces.

Understanding this motion is particularly important in the context of athletic training and rehabilitation, as inversion plays a crucial role in the mechanics of the foot and ankle. It can also be a common movement associated with certain injuries, making it relevant for health and fitness professionals to understand the implications of inversion in their practice.
