5-1 How to Activate the
"Stance-Flexion" Function
Fig. 15 shows how to apply the body weight
to the prosthesis. When the weight is
placed on the heel as shown in the left
figure while the knee is fully extended, the
knee is automatically locked (self-locked)
and slightly flexed (stance-flexion). The
maximum flexion angle is 10° depending on
the load and the setting of the adjustment.
If the weight is placed on the toe as shown
in the right figure, the lock is released.

on floor reaction force
Until the user gets used the knee joint,
confirm that he/she understands the
self-locking function while holding on the
parallel bars and placing weight on the
CAUTION
prosthesis. He/She should be thoroughly
familiarized with the function prior to use.
In a standing posture, put the prosthesis
slightly forward, and weight on the heel
side while fully extending the knee. If the
weight is placed when the knee is not
fully extended or the toe side is in contact
with the floor, knee buckling may occur,
and the user may fall down. Particularly
users who have a habit of standing with
their prostheses slightly backward shall
keep this in mind.
Instruct the user to put the prosthesis
slightly forward in a standing posture and
CAUTION
place weight on the heel side while fully
extending the knee. If the weight is
placed when the knee is not fully
extended or the toe side is in contact with
the floor, knee buckling may occur, and
the user may fall down. Give a sufficient
explanation particularly to users who
have a habit of standing with their
prostheses slightly backward.
