Twist® Expand


Twist® for forefoot / retopie measurements.

This instrument allows to measure the orientation of the front part of the foot in relation to the heel in a neutral position of the subtalar joint, with the articulation of the midtarsal at the end of the pronatory stroke.
This measurement is fundamental for the manufacture of functional corrective orthoses.
The combination of the inclination of the calcaneus and the metatarsal support is accurately read on the graduated sphere, thus offering a combination of comparative measurements.
The bisectrix of the traced calcaneus serves as a reference for the analysis.
The five heads of the metatarsals rest on the Twist® instrument, while the bisector of the heel is centered by the special window.
