Subtalar Joint Axis Rotational and Translational Motions During Closed Kinetic Chain Pronation and Supination - Sagittal Plane Motion In this three dimensional animation of the medial view of the weightbearing foot skeleton during closed kinetic chain subtalar joint (STJ) pronation and supination, the STJ axis is noted to undergo plantarflexion during pronation and dorsiflexion during supination. As the talus plantarflexes during STJ pronation, note how the STJ axis plantarflexes along with the

Subtalar Joint Axis Spatial Location Changes with Subtalar Joint Rotational Motions The subtalar joint (STJ), is a triplanar joint made up of the articulations between the talus and calcaneus. One of the main functions of the STJ is to allow transverse plane rotations of the leg to be converted into frontal plane rotations of the foot. With STJ pronation, the calcaneus dorsiflexes, abducts, everts and posteriorly translates relative to the talus. With STJ supination, the calcaneus plantarflexes,

Subtalar Joint Axis Palpation Technique In this video, I demonstrate the Subtalar Joint Axis Palpation Technique which I iinvented in 1984 and first published a description of the technique 33 years ago (Kirby KA: Methods for determination of positional variations in the subtalar joint axis. JAPMA, 77: 228-234, 1987). The STJ Axis Palpation Technique is performed in this video on a fresh-frozen cadaver foot that has been thawed to room temperature at Penn State Biomechanics Lab for research on s
