7.3.5.2 Orthosis construction with Sensor Ankle
This function must be practised and executed consciously. Only by properly stepping down with
the sole can the product respond correctly and permit controlled flexion.
1) Hold the handrail with one hand.
2) Position the leg with the product on the step so that as much of the sole of the foot as pos­
sible is on the step.
3) Place the foot of the less affected leg onto the next step.
4) Place the foot of the leg with the product on the next step after that.
7.3.6 Walking up stairs
CAUTION
Walking up stairs
Falling due to foot being placed incorrectly on stair as a result of changed damping behaviour.
► Always use the handrail when walking up stairs and place most of the sole of your foot on
the stair surface.
► Always step up with the less affected leg, followed by the leg with the product. Support from
the Spring Element while walking up stairs (bouncing with the product extended) is not
allowable and must be avoided. This type of load can cause the product to switch to the
swing phase (no damping).
► Particular caution is required when carrying children up the stairs.
The product does not have an active drive system to support this movement
pattern.
1) Hold the handrail with one hand.
2) Place the foot of the sound leg on the first step.
3) Pull up the leg with the product.
7.3.7 Walking backwards
CAUTION
Risk of falling when walking backwards
Falling due to unexpected product behaviour because of changed damping behaviour.
► Extending the knee joint and placing load on the toes may cause the product to switch to the
swing phase (no damping).
► When walking backwards, take smaller steps and put a consistent load on the foot in order
to prevent unintentional buckling due to switching to the swing phase.
Walking backwards with the knee joint extended and the toes on the floor res­
ults in a forefoot load. This may cause the product to switch to low flexion res­
istance. This means there is a risk of falling.
In order to avoid this risk, practice walking backwards under the instruction of
trained, qualified personnel.
