The subtalar joint moves through a combination of gliding and rotation. Clinically, these movements are recognized as inversion and eversion, which are considered the primary movements occurring at this joint. It's important to remember that foot mechanics don't happen in isolation.
Subtalar Joint Movements Explained
The subtalar joint is a key articulation in the foot, and its movements are essential for adapting to uneven surfaces and maintaining balance. Here's a breakdown of the movements:
- Gliding: Refers to the bones sliding across one another.
- Rotation: Refers to the bones turning around one another.
- Inversion: The sole of the foot turns inward.
- Eversion: The sole of the foot turns outward.
These movements allow for complex adaptations during activities like walking and running.
Summary of Subtalar Joint Motion
| Movement | Description |
|---|---|
| Gliding | Bones slide across each other. |
| Rotation | Bones turn (rotate) relative to each other. |
| Inversion | Sole of the foot turns inward. |
| Eversion | Sole of the foot turns outward. |
