Ankle & Foot
Evidence: confirmed
Ankle Range of Motion Special Test
Orthopedic Physical Examination & Clinical Assessment Guide
What is it used for?
- Measuring the degrees of movement available at the ankle joint.
How to Perform
- Dorsiflexion: Move the foot upwards towards the shin (Standard: 20-30°).
- Plantar flexion: Point the foot downwards (Standard: 40-50°).
- Pronation/Supination: Assess the rolling motion of the foot (Pronation: ~30°, Supination: ~60°).
- Rotation: Assess slight rotational movements (Standard: ~5°).
Clinical Tips & Notes
| Movement | Degrees |
|---|---|
| Dorsiflexion | 20-30 |
| Plantar flexion | 40-50 |
| Rotation | 5 |
| Pronation | 30 |
| Supination | 60 |
Clinical Context & Limitations
The Ankle Range of Motion should be considered as one component of a comprehensive musculoskeletal assessment. No single special test has perfect diagnostic accuracy; thus, clinical decision-making should integrate test results with patient-reported symptoms, mechanism of injury, functional impairment, and relevant imaging.
Clinicians should be aware of potential false-positive results in patients with pain sensitisation, muscle guarding, or poor relaxation. For the Ankle & Foot region, combining the Ankle Range of Motion with complementary examination tests significantly improves overall diagnostic confidence.
