The tested range of the subtalar joint orientations (2[degrees] of inversion to 4[degrees] of eversion) was smaller than its passive full range of motion.
Subtalar joint eversion is usually accompanied with abduction and dorsiflexion of the calcaneus in open kinetic chain motions.
When the subtalar joint was positioned at 2[degrees] of eversion, we found that the projection volumes under the medial midfoot and hindfoot regions of the plaster of Paris models were significantly lower than the other three subtalar joints positions.
Guidelines are usually followed to orientate the subtalar joint at a neutral position during molding for foot orthoses [7-8] because there is a common belief that the foot resting on the orthosis will be everted if the subtalar joint is aligned in such a way during foot impressions.
However, the differences in medial and longitudinal arch heights and navicular protrusions among all subtalar joint orientations were small.
91) measuring the subtalar joint angles during relaxed standing position.
The main reason for choosing the non-weight-bearing molding method, which was commonly used in Australia and New Zealand , was to ensure that the forefoot could be aligned at 90[degrees] to the rearfoot during the molding process at different subtalar joint orientations.
This study investigated the effects of subtalar joint orientations on the shape of the positive model.
Controversy exists as to how the subtalar joint should be aligned during foot molding for foot orthoses.
Reappraisal of the negative impression cast and the subtalar joint neutral position.

Clinical measurement of the axis of the subtalar joint.
