How Much Does the Talocrural Joint Contribute to Ankle Dorsiflexion Range of Motion During the Weight-Bearing Lunge Test? A Cross-sectional Radiographic Validity Study

摘要

BACKGROUND: Ankle dorsiflexion range of motion is commonly measured during the weight-bearing lunge test (WBLT) as the horizontal knee distance traveled or tibial inclination. These measures are assumed to represent talocrural dorsiflexion, yet have not been validated against radiographic images.
