Heel too hard
Symptoms
Possible solutions
• Fast knee flexion, low stability
• Transition from heel strike to toe-off too
fast
• Energy return feels low
• Shift prosthetic socket back relative to
the foot
• Reduce the heel stiffness (shift or
remove heel wedge)
Prosthetic foot too stiff
Symptoms
Possible solutions
• Minimal rollover movement of the pros­
thetic foot at low walking speed (long
full ground contact)
• Select prosthetic foot in lower stiffness
Prosthetic foot too soft
Symptoms
Possible solutions
• Clicking noise at the start of ground
contact.
• Very pronounced deformation of the
forefoot at high activity levels
• Select prosthetic foot in higher stiff­
ness
5.1.3.1 Optimising the heel characteristics
The behaviour of the prosthetic foot at heel strike and during heel contact in
the mid-stance phase can be adapted with the placement of a heel wedge.
The heel wedge is attached with adhesive tape for testing. For definitive
assembly, it is glued to the prosthetic foot.
Fitting
1) Place the double-sided adhesive tape (included) on the underside of the
heel wedge.
2) Place the heel wedge on the base spring in the recommended position.
3)
Optional:
Shorten the heel wedge on the top if the heel strike is too
hard.
Definitive assembly
1) Remove the adhesive tape from the heel wedge. This can be done using
a cloth with acetone.
2) Roughen the contact surface on the prosthetic foot slightly using sand­
paper. Remove the dust after sanding.
3) Glue the heel wedge to the prosthetic foot with contact cement.
