►
cian.

►
Instruct the patient to see a physician immediately if any exceptional changes are noted (e.g.
►
worsening of the complaint).
5.1 Size Selection
► Select the orthosis size based on the shoe size (see sizing table).
5.2 Adaptation
CAUTION
Improper moulding or application
Injuries or damage to the orthosis due to overloading of the material and improper fit of the
orthosis due to breakage of load-bearing components
Do not make any improper changes to the orthosis.
►
Always apply the orthosis according to the information in the instructions.
►
NOTICE
Damage due to improper handling (heat treatment, drilling holes)
Loss of orthosis functionality
Do not carry out any heat treatment on the orthosis. The orthosis is not thermoformable.
►
Do not drill any holes in the bottom of the sole or the connecting elements as holes break the
►
fibres and weaken the component.
NOTICE
Use without suitable footwear
Restriction of functionality due to insufficient stabilisation
Only use the orthosis with closed footwear, taking the allowable effective heel height into
►
account.
Attaching the calf strap to the lower leg shell
1) Open both straps and detach them from the hook-and-loop (see fig. 2, see fig. 3).
2) Pull the padding over the wings of the lower leg shell, positioning the padding on the inside
and the strap on the outside of the shell (see fig. 4, see fig. 5).
3) Tighten the straps and attach them to the hook-and-loop on the opposite wing of the lower leg
shell (see fig. 6, see fig. 7).
Selecting footwear
► Choose a sturdy shoe with laces or hook-and-loop fasteners and a solid toe cap to ensure the
optimal effectiveness of the orthosis. The effective heel height should be between 0.5 cm and
1.5 cm.
Adapting the orthosis
1) If the patient uses footwear with removable insoles, take the insole out of the shoe on the fit­
ting side.
INFORMATION: Keep the insole to use the shoe without the orthosis.
2) Have the patient sit on a chair with footwear and without the orthosis. Position the foot at a
90° angle to the lower leg (see fig. 8).
3) Mark the position of the ankle joint in the shoe with a small piece of adhesive tape (see fig. 8).
