What is the normal inversion ROM of the ankle?

Explanation:
Inversion of the ankle is the movement that turns the sole of the foot inward. The normal range for this motion is about 20 degrees. When measuring, you position the patient with the knee bent around 90 degrees, stabilize the tibia, and use a goniometer with the axis over the ankle joint, the stationary arm along the tibia, and the moving arm along the calcaneus. Values near 20 degrees are typical, with some natural variation between individuals. A reading around 40 degrees is greater than normal and could indicate hypermobility or a measurement error, so ensuring proper technique and alignment is important.
