Shoulder Flexion
Biomechanical analysis of shoulder flexion and extension range of motion assessment.
Shoulder Flexion
Overview
The shoulder flexion assessment evaluates the range of motion and quality of movement in the shoulder during forward and backward movement. This assessment measures the ability to achieve sufficient flexion and extension while maintaining proper alignment.Events
| Event | Data Type | Description |
|---|---|---|
| Max Flexion | Int | Frame of maximum shoulder flexion |
| Max Extension | Int | Frame of maximum shoulder extension |
Discrete Metrics
| Metric | Data Type | Units | Description |
|---|---|---|---|
| MaxFlexion | Float | degrees | Maximum shoulder flexion |
| MaxExtension | Float | degrees | Maximum shoulder extension |
| SufficientFlexion | Boolean | - | Whether flexion is sufficient (≥ 165°) |
| SufficientExtension | Boolean | - | Whether extension is sufficient (≥ 40°) |
Notes
- All angular measurements follow ISB conventions
- Measurements are based on ShoulderAngleWRTTrunkXYZ.X
- Sufficient flexion is defined as ≥ 165°
- Sufficient extension is defined as ≥ 40°
