Intraclass correlation coefficients of absolute agreement and consistency between the Vicon and Captury systems.

Note: KHR (Knee-Hip separation distance ratio), AHR (Ankle-Hip separation distance ratio), KF (Knee Flexion), ADF (Ankle Dorsi Flexion), HF (Hip Flexion), FPKA (Frontal Plane Knee Angle), FPKD (Frontal Plane Knee Deviation), FPPA (Frontal Plane Projection Angle), KVarus (Knee Varus). Range values used to group ICC values as either “poor” (< 0.5), “moderate” (0.5–0.75), “good” (0.75–0.9) or “excellent” (> 0.9) are marked by the background colors (red, yellow, light green, and dark green)
