(Shin Vertical, load line
through knee centre)
With user standing and
limb loaded
With 100% weight on limb,
can the user flex the knee?
Note...Wearer standing
in parallel bars , gently
holding rails.
Increase
dorsiflexion
resistance.
Is the
Stanceflex
rubber too
soft?
Is the knee fitted with a
Stanceflex rubber?
Check level of stability
is sufficient for amputee
needs and adjust
accordingly**
**Note,
There may
be a need to
compromise
between
maximum
walking speed
and level of
stability
Adjustment complete
If reducing the sensitivity
fails to have any effect
other than reducing the
stability, check that the
front stop is properly
adjusted
i.e. contacting the chassis
when loaded. Failure to
do so can result in the
brake operating when
hyper- extended
Does the foot have a low
dorsiflexion resistance?
Ask user to walk
SLOWLY
Ask user to walk
at NORMAL speed
Does the knee release
smoothly at toe off?
Ask user to walk
FAST
Does the knee release
smoothly at toe off?
