loading_phase_excessive_knee_valgus - Optimal Direction: Lower is better
- Unknown Value: -1
- Measurement: Front and back knee valgus classification level during the loading phase
- Threshold: Front or back knee valgus classified as “high”
Description
Loading phase excessive knee valgus is a binary indicator that flags when either the front or back knee is classified as having a “high” level of inward (valgus) collapse during the loading phase, which is a common indicator of increased lower-body injury risk. High knee valgus occurs when the knee moves medially (inwards towards the centerline of the body) more than 6% of height. Moderate knee valgus occurs when the knee moves medially more than 2% of body height. Normalized distances (% of height) aid in metric consistency across athletes of various sizes.Use Cases
- Injury risk identification
- Lower-body mechanics evaluation
