RF POST POSITION (INVERTED): EXAMPLE: If the number 4 is placed in this blank, the orthosis will be inverted 4 degrees at the heel contact phase of gait. If the number 0 is placed in this blank, the rearfoot post will be parallel to the anterior edge of the orthosis.
RF POST MOTION (EVERSION): EXAMPLE: If the number 4 is placed in this blank, the orthosis will evert 4 degrees during the midstance phase of gait. If the number 0 is placed in this blank, there will be no rearfoot post motion ground into the rearfoot post.
LATERAL & MEDIAL FLANGE, HEEL CUP HEIGHT AND HEEL LIFTS: These modifications are only used according to individual patient requirements. See production standards for further information regarding any of these items.
MET RAISE (RIGID): This modification is built into the cast and is therefore transferred to the orthosis plate during vacuum forming.
MET RAISE (SOFT): Soft met raises are added to the top of the orthosis plate and their leading edge is placed approximately 5 to10mm distal to the anterior edge of the orthosis plate.
