Make sure that the amputee always holds a handrail during gait training. There
is a risk that amputee loses balance and falls down.

Countermeasures
When the amputee descends
stairs, yielding does not
function.
Check if the floor contact
position of the foot is
appropriate.
Put the mid-foot on the edge
of stairs.
J
See (page 20). *
Check if the way to apply
body weight is proper.
POINT 1
POINT 4
Practice how to fully apply
body weight to the heel.
J
See (page 14). *
Check if alignment is proper.
Adjust so that body weight can
be fully applied to the heel.
Check if the prosthetic foot
has adequate heel stiffness
(not too soft).
Select a prosthetic foot with
medium heel stiffness.
The above measures can not
resolve the problem.
Contact your local sales
representative/dealer.
Yielding function is not
sustainable when the
amputee descends a slope.
Even if the knee is fully
extended, it is flexed by its
self-weight before the foot
contacts the floor.
Repeat gait training of how to
shift the body weight forward
and to obtain the best timing
of swing and landing. *
Even after gait training, the
amputee cannot fully extend
the knee joint.
Select a pneumatic cylinder
with a strong spring to assist
extension. During its use,
however, the amputee may
feel heaviness during swing
motion in the swing phase.
The above measures can not
resolve the problem.
Use of yielding for stairs
should be prohibited.
Check if the toe touches the
floor first due to insufficient
knee extension.
By swinging the prosthesis,
fully extend the knee joint. Be
sure to put the mid-foot on
the edge of the stairs. *
