Recent studies recommend a supinated foot position as a more reliable foot position for measuring the clinical ankle joint range of motion and propose it as a potential standard.
A New Paradigm. A New Definition.
Current literature shows that "subjects with less than - 5 degrees of dorsiflexion during static examination did exhibit reduced ankle range of motion during gait."
An Updated Field Guild Guide: Goniometer
- Use your thumb and index finger to stabilize the vertical arm along the bisection of the fibula. Align the horizontal arm parallel with the bottom of the foot (weight-bearing surface)
- Supinated the whole foot while maintaining goniometer alignment
What to Document
- DF with the knee extended (foot supinated)
- DR with the knee flexed (foot supinated)
- The total range of motion - plantarflexion/dorsiflexion (not supinated)
