Is it important to position foot in subtalar joint neutral position during non–weight-bearing molding for foot orthoses? J Rehabil Res Dev. 2012;49(3):459–66. http://dx.doi.org/10.1682/JRRD.2011.03.0049 Slideshow Project DOI:10.1682/JRRD.2011.03.0049JSP Aim – Reveal whether foot shape changed in molds taken with the subtalar joint at different orientations. Relevance – This study may provide useful information regarding non–weight-bearing foot molding techniques for the field of foot orthotics.

Is it important to position foot in subtalar joint neutral position during non–weight-bearing molding for foot orthoses? J Rehabil Res Dev. 2012;49(3):459–66. http://dx.doi.org/10.1682/JRRD.2011.03.0049 Slideshow Project DOI:10.1682/JRRD.2011.03.0049JSP Methods During non–weight-bearing casting, subtalar joints were aligned at following positions: – 4° of eversion. – 2° of eversion. – 2° of inversion. – Neutral. At each orientation, forces were applied over forefoot so metatarsal heads were aligned with rearfoot. Digital scanning was used to analyze shape of each negative mold.

Changes in arch heights, navicular height, and protrusion were insignificant and very small.
