Anatomy, Range of Motion and Neutral Position of the Subtalar Joint The talus and calcaneus make up the two bones of the subtalar joint (STJ), otherwise known as the talo-calcaneal joint. The STJ consists of three articular facets, the posterior, middle and anterior facets. The two physiologic motions of the STJ are supination and pronation. During STJ supination, the talus glides posterior-superiorly on the posterior facet of the calcaneus. During STJ pronation, the talus glides anterior-inferi

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 Mobilization In this video excerpt, Erik demonstrates one method for mobilizing the subtalar joint. People need functional movement in the subtalar joint to lessen wear and tear and reduce damaging knee, hip, and low back compensation. Pain from plantar fasciitis and medial shin splints often have roots in a dysfunctional talocalcaneal articulation where the talus has glided forward on the calcaneus and become fixated there. Would you like to learn manual techniques to mobilize th
