| Functional Foot Orthosis (as relates
to custom foot orthosis) - An orthotic device that is contoured to the
plantar, medial, lateral and posterior aspect of a replication of the foot
to control or reduce abnormal motion or abnormal position of the foot and
to control the abnormal motion or abnormal position of the lower extremity
that is affected by the position and/or motion of the foot. When
applicable, modifications such as wedgings or postings are utilized to
control foot motion or position.
A.
Rigid Functional Orthosis - A Functional Foot Orthosis made to maximally
prevent abnormal motion or abnormal position of the foot and leg during
gait. This device is made from a rigid material that displays minimal
flexibility during use, given that this flexibility is a function of the
thickness of the material, the intrinsic rigidity of the material, the
size of the orthotic plate, the weight of the patient, and the degree of
instability of the foot.
B. Semi-Rigid Functional Orthosis - A Functional Foot Orthosis
used to partially control abnormal motion or abnormal position of the foot
and leg during gait. This device is made from a material that displays
moderate flexibility during use, given that this flexibility is a function
of the thickness of the material, the intrinsic rigidity of the material,
the size of the orthotic plate, the weight of the patient, and the degree
of instability of the foot .
