INSERTION INTO SHOE
• Ifpresent,removetheinsertfromtheshoe.
• InsertthefootplateoftheAFOintotheshoe,ifnecessarygrindthefootplateto
fit the shoeshape or adjust the shape to the contours of the foot.
• Avoidgrindingexcessivematerialfromthelateralsideofthefootplateensuring
sufficient space between the medial strut and the medial arch of the (Drop-)
foot (figure 1).
• Ensurestabilityofthefootplateontheshoesolethroughouttheentirelength
of the shoe.
• Makesurethefootplateand(or)theinsertcovertheentirelengthoftheshoe
to avoid AP displacement (figure 2)
• Ifavailable,placetheinsertontopofthefootplate.
• HavethepatientdontheshoeandtheAFO.
FITTING THE AFO TO THE PATIENT
• ShifttheAFOanteriororposteriortoobtainaclosefitbetweenthedistalpart
of the anterior shell and the lower part of the tibia (figure 3).
• Ifthedistalsectionoftheanteriorshellistoofarfromtheleg,itmaybe
because the heel section of the footplate is too long. Trim the footplate at the
heel end and add length to the toe part of the footplate.
• Theorthosisisnowreadytobefittedtothepatient.
DONNING THE AFO
• Thepatientisinseatedpositionwithkneesin90°flexionandankleinneutral
position
• AlwaysinserttheAFOintotheshoepriortodonningittothepatient.
• Alignthedistalsectionoftheanteriorshelltoobtainclosecontacttothelower
part of the tibia and secure this position by fastening the
velcro (figure 4).
• Fixatethelowerstrapensuringthepositionofthelowerpartoftheshelltothe
tibia.
• TheC(P)Oisadvisedtodeterminethecorrectdistancebetweenthetwo
anterior support members alongside the bony prominence of the tibia in order
to ensure equal pressure distribution. Apply the strap over the 2 frontal Velcro-
parts from medial to lateral (figure 5).
• Oncethispositionisdetermineditdoesn’trequireadjustmentinthefuture.
The patient can now apply the strap around the calf using
one hand only (figure 6).
• Pointouttothepatientthatdoffingtheorthosis,itissufficienttoreliefthis
part of the strap, maintaining the position of the anterior support members.
CUSTOMIZING THE AFO
The following procedures are not part of the standard fitting of the orthosis and
will only be carried out according to specific needs of the patient.
1. Standardized padding material is available. This can be applied according to
thepatient’swishes.Itisadvisedtoprovidepaddingontheanteriorshell
alongside the tibia and on the medial strut covering the malleoli.
2. The use of the lower lateral support member strongly depends on the degree of
voluntarycontrolandtheselectionoftheshoe.Incaseof
sufficient control it is advised to remove the lateral support member according
to the line shown in picture 7.
3. Ifthedistalsectionoftheanteriorshellcausesexcessivepressureontheleg,
the footplate should be trimmed at the toe. The lack of
length at the heel is compensated by correct placement of the insert.
4. The Carbon fiber orthosis is fabricated to accommodate approximately 1,7cm
(6/9inch)heel-height.Iftheshoehasasignicantlyhigherorlowerheel,add
or reduce the heel height by adding on material under the footplate.
5. Itisrecommendedtouseawell-ttingo-theshelforacustom-madeinsolein
combination with the Dynamic AFO. This is especially the
case with excessive pronators where the insole can prevent the medial
malleolus and the navicular bone from getting in contact with the medial strut
