Sitting Down - Ossur TOTAL KNEE 1900 Bedienungsanleitung

PRODUCT-SPECIFIC TRAINING
Instructing new users is essential to achieve a successful rehabilitation.
For safety, initial adjustments and gait training should be done with
patient standing between parallel bars.
LEVEL GROUND WALKING
• Explain to the user the function of stance flexion/geometric lock.
Patients who previously wore a knee without stance flexion function
may fear collapse of knee during loading response. They must be
trained to allow the knee to move into stance flexion and not to
prevent it by strong hip extension
• Explain the stance release mechanism to the patient. Patient's centre
of mass must be anterior to the pivot axis of knee. In this position,
very little hip flexor effort is required to initiate knee flexion. Knee
flexion will be initiated through rotation of the hip as weight is
transferred onto the ball of the foot during terminal stance.
• Allow patient to stand in the parallel bars with their weight over the
ball of the foot. Initiate knee flexion with pelvic rotation and slight hip
flexion. Repeat several times.
• Start walking within parallel bars. As confidence increases, start
walking outside of the parallel bars.

SITTING DOWN

• Have the patient move their centre of mass forward over the toe.
• Place feet evenly (or prosthetic foot slightly posterior), shift weight
anterior onto forefoot. Knee will release.
• Use sound limb to accept weight for sitting.
STAIR DESCENT
Walking step over step down stairs with Total Knee requires much
practice and should only be attempted by trained Total Knee users. egin
practicing on lowest step and use handrail.
• Place entire foot on step.
• Move centre of mass over forefoot as for sitting. Knee flexion will be
initiated. Knee flexion will be rapid. Use caution!
• Increase number of steps as patient becomes confident.
Not all users will be able to learn step over step stair descent.
MANUAL FLEXION
When sitting with fully extended Total Knee it may be necessary to flex
knee manually. Press two points shown in Figure 14 to release knee into
flexion. Be careful not to pinch fingers in the linkages.(Patient may also
reach out and pull or tap toe of prosthesis to release).
Caution! Avoid placing hands or fingers near moving
joints.
