8.3 Movement patterns in basic mode (mode 1)

8.3.1 Standing

Knee control through high flexion resistance and static alignment.
The knee joint of the product has no locking function, so that slow bending is
possible under flexion load. To restore the stable standing position, place the
leg back under the body and put weight on the heel.
A stance function can be enabled by the O&P professional. Please see the fol­
lowing section for further information on the stance function.

8.3.1.1 Stance function

INFORMATION
To use this function, it must be enabled by the O&P professional. It also has to be activated
using the Cockpit app (see Page 83).
The stance function is a functional supplement to the basic mode. This function makes it easier
for the user to stand on an inclined surface for a longer time. The joint is fixed in the flexion direc­
tion at a flexion angle between 5° and 65°.
The standing function must be enabled by the O&P professional. In addition, the type of joint
locking (intuitive/manual) has to be established by the O&P professional. Changing the locking
type using the Cockpit app is not possible.
Intuitive locking of the joint
The intuitive stance function recognises any situation that puts strain on the orthosis in the flexion
direction but where flexion is not permitted. Examples of this include standing on uneven or slop­
ing surfaces. The joint is always locked in the flexion direction when the leg with the orthosis is
not fully extended and is kept still for a brief moment.
The joint is not locked when the above conditions are met and a sitting position is assumed.
Intuitive unlocking of the joint
► Upon forward or backward rollover or extension, the flexion resistance is immediately
switched from high to stance phase resistance again.
Manual joint lock
► Flex the joint between 5°and 60°.
→ Now the blocked joint can be loaded in the flexion direction.
Releasing the manual joint lock
► The Manual Stance function is automatically deactivated again by extending the knee or by
repositioning the leg (e.g. taking a step).

8.3.2 Walking

Initial attempts at walking with the product always require instruction from
trained, qualified personnel.
The hydraulics stabilise the knee joint in the stance phase and release the
knee joint in the swing phase so that the leg can swing forward freely.
Switching to the swing phase requires rolling the product over to the front out
of the stride position.
An acoustic feedback signal when initiating the swing phase can be activated
by the O&P professional.
