9.2 Movement patterns in basic mode (mode 1)
9.2.1 Standing
The intuitive stance recognises any situation where the prosthesis is kept still while standing.
The standing position is stabilised through high dorsiflexion damping with vertical lower leg.
Plantar flexion is only dampened to a minor extent to allow the lower leg to be retracted to
the neutral position for correction of the standing position.
This function is deactivated during rollover to the front or by lifting the prosthesis off the
floor.
Coming to a stop with the prosthesis side after walking can lead to the knee joint sinking in
as a result of the ankle position during the rollover. To restore a stable standing position,
place the leg back under the body and stretch the leg or put weight on the heel.
The relief function can be used when standing (see page 66).
9.2.2 Walking
Initial attempts at walking with the prosthetic foot always require instruction by trained, quali­
fied personnel.
When walking, the damping of the dorsiflexion and plantar flexion is adapted to the current
walking phase, making a physiological gait possible.
Plantar flexion damping is increased during heel strike in order to provide support for stance
phase flexion in the knee.
By increasing dorsiflexion damping in the stance phase, the lower leg is led into an extended
rollover angle. The rollover behaviour automatically adjusts itself to the walking speed.
Plantar flexion damping is increased during the transition to the swing phase in order to pre­
vent the toes from dropping and to maintain ground clearance.
During the swing phase, plantar flexion damping is adjusted to the current position of the
lower leg at all times. This ensures a comfortable tread, with suitable heel leverage for the
respective step length.
