8.2 Movement patterns in basic mode (mode 1)

8.2.1 Standing

The intuitive stance function recognises any situation where the prosthesis is
kept still while standing. The prosthesis prevents tipping forward, stabilising
the user.
During rollover to the front or when the prosthesis is lifted off the floor, the
prosthesis leaves the intuitive stance function automatically and switches back
to the walking function.
When coming to a stop while walking, the leg must be set under the body and
extended or weight has to be placed on the heel.
The relief function can be used when standing (see Page 66).

8.2.2 Walking

Initial attempts at walking with the prosthesis always require the instruction of
trained, qualified personnel.
The prosthesis stabilises the user in the stance phase. The rollover behaviour
automatically adjusts itself to the walking speed. Dropping the tip of the foot is
prevented in the swing phase to maintain ground clearance. Even before
ground contact, damping of the prosthesis is adjusted to make stepping down
comfortable and quickly achieve full ground contact.

8.2.3 Sitting down/sitting
