• 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. Begin
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 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).
C! Avoid placing hands or fingers near moving joints.
