Overground Gait
Stride kinematics, stance/swing ratio, and bilateral hip–knee–ankle coordination.
Setup
- Walk at preferred speed across the frame; 4–6 steps minimum
- Camera perpendicular to the line of progression
- Full foot including heel-strike and toe-off in view
Scoring rubric
- Knee flexion in swing ~60°
- Ankle: heel strike to plantarflexion rocker
- No vaulting or hip hike as a primary strategy (frontal view if flagged)
