Walking Up A Ramp; Standing On Inclined Surface; Kneeling; Relief Function - Ottobock 1B1-2 Gebrauchsanweisung

8.2.9 Walking up a ramp

With the first step, the foot is already adjusted to the inclination of the ramp,
making a rollover possible if the step is on the heel or middle of the foot. In
order to do so, the lower leg should positioned almost perpendicular to the
surface of the ramp and the full area of the foot should be placed on the sur­
face.
When stepping on the forefoot with the lower leg at a steep angle (e.g. on very
steep ramps), the foot secures dorsiflexion, which enables the body to be lif­
ted in a stable manner.

8.2.10 Standing on inclined surface

Standing on an inclined ground surface is no different to standing on a level
surface. The foot stabilises in dorsiflexion when the lower leg is perpendicular.
Put weight on the heel in order to lower the forefoot (e.g. when standing in a
downward direction).
Perform one of the following motions in order to continue to walk on a down­
ward-sloping ground surface from the standing position:
•
•
The relief function can be used when standing on an inclined surface (see
Page 67).
Wearing shoes with heels limits the range of incline, so it may not be possible
to achieve a perpendicular lower leg.

8.2.11 Kneeling

If the leg with the joint is tilted backwards, plantar flexion damping is reduced,
making it possible for the foot to bend so the lower leg can lie flatter to the
ground surface.

8.2.12 Relief function

When weight is evenly placed on the heel without movement for more than
2 seconds, the tip of the foot lowers to reach a more natural foot position.
Possible applications include sitting with the heel in front of the knee axis,
standing while leaning against something, and standing on a downward slop­
ing surface.

8.3 MyModes

With the help of adjustment software, the O&P professional can activate and configure MyModes
in addition to the basic mode. These can be selected by using the Cockpit app or movement pat­
terns. Switching by using movement patterns has to be activated in the adjustment software by
the O&P professional.
Start the first step with the prosthesis side.
Deliberately produce a rollover motion with the prosthesis side.
The prosthetic foot then yields in dorsiflexion, in order to allow the body's
centre of gravity to drop before the heel of the other leg strikes.
