Ankle Dorsiflexion
Biomechanical analysis of ankle dorsiflexion range of motion assessment, including measurement positions and discrete metrics.
Ankle Dorsiflexion
Overview
The ankle dorsiflexion assessment evaluates the range of motion and quality of movement in the ankle joint. This assessment can be performed in either a standing or half-kneel position, and measures the ability to achieve sufficient dorsiflexion while maintaining proper alignment.Events
| Event | Data Type | Description |
|---|---|---|
| Assessment Position | String | ’standing’ or ‘half-kneel’ based on knee and hip angles |
| Footedness | String | ’left’ or ‘right’ indicating which foot is being tested |
Discrete Metrics
| Metric | Data Type | Units | Description |
|---|---|---|---|
| AssessmentPosition | String | - | Assessment position (‘standing’ or ‘half-kneel’) |
| Footedness | String | - | Which foot is being tested (‘left’ or ‘right’) |
| MaxFlexion | Float | degrees | Maximum dorsiflexion angle |
| Excursion | Float | degrees | Total range of motion |
| SufficientFlexion | Boolean | - | Whether flexion is sufficient (≥ 30°) |
| BackKneePassFrontAnkle | Boolean | - | Whether back knee passes front ankle |
Notes
- All angular measurements follow ISB conventions
- Assessment position is determined by knee and hip angles (threshold of 80°)
- Footedness is determined by hip angle patterns
- Sufficient dorsiflexion is defined as ≥ 30°
