Lucy's Flat Feet: The Relationship between the Ankle and Rearfoot Arching in Early Hominins
Figure 5
Correlation between tibial arch angle and measures of flat foot in humans.
There is a statistically significant positive correlation between the tibial arch angle and two measures of asymptomatic flat-footedness, the talar declination angle (A), and the talocalcaneal angle (B). A regression line generated using reduced major axis regression is drawn in each graph.
