Inversion of the foot is a movement where the sole of the foot turns inward, toward the midline of the body.
Understanding Foot Movement
To fully grasp inversion, it's helpful to understand the different ways the foot can move. Here's a brief overview:
- Inversion: The sole of the foot turns inward.
- Eversion: The sole of the foot turns outward, away from the midline, as explained in the provided reference [0:11].
Movement | Description | Direction |
---|---|---|
Inversion | Sole of the foot turns inward | Towards the midline of the body |
Eversion | Sole of the foot turns outward | Away from the midline of the body |
How Inversion Works
Inversion primarily occurs at the subtalar joint, which is located below the ankle joint. This movement allows the foot to adapt to uneven surfaces and is essential for walking and running.
Example
Imagine you are walking on a slightly uneven ground. Your foot might invert slightly to maintain balance and contact with the ground.
Inversion and Eversion in Movement
The video referenced [0:11-1:19] explains that eversion is the opposite movement, with the foot turning outwards. Both inversion and eversion are important movements for ankle and foot stability, which are frequently done when engaging in activities such as walking.
- Inversion and eversion can happen simultaneously as part of a complex foot movement.
- They help with shock absorption.
- They assist with balance.
In summary, inversion of the foot is a fundamental movement that allows the sole of the foot to turn inward, essential for balance, stability and navigation of uneven terrain.
