Understanding of the effect of weightbearing on the kinematics of the subtalar and talocrural joints is critical for the diagnosis and treatment of foot and ankle disorders. However, precise kinematics of these joints during dynamic activities in vivo is not well studied. The purpose of this study was to compare in vivo kinematics of these joints during nonweightbearing and weightbearing activities in healthy subjects.
Coupled motion of the subtalar and talocrural joints during weightbearing activity serves to maximize joint contact area and stabilize the subtalar joint. 3D-2D model registration techniques appear to be useful tools for the quantitative analysis of the talocrural and subtalar kinematics during dynamic activities.
