Fitting Tips & Troubleshooting
The following fitting tips will help to optimize
Kinterra’s
performance. If the proposed
solutions do not result in a satisfactory outcome, please contact Freedom Innovations
Technical Services for further support.
Foot too stiff / too soft
As a first step, weigh the patient to confirm current body weight. Assess true impact level
(low or moderate) and review the Kinterra-specific category selection chart to assure the
proper foot stiffness has been selected.
Heel is too soft
Symptoms:
• Sinking at heel strike, ‘crushing’ the heel
• Difficult to progress
the step from heel strike to mid stance
• User feels they are walking u
p hill or forefoot feels too long
Solutions:
•
Check A-P alignment; ensure foot is not positioned too far anterior
•
Increase the plantar flexion
‘PF’
resistance
•
Temporarily apply the provided rubber heel stiffening bumpers to the heel in the
location indicated on the bumper package using the pre-applied adhesive. This will
increase stiffness one category level. Placement anterior to this will further stiffen the
heel and a more posterior placement will stiffen less than a full category. For permanent
placement, clean off the pre-applied adhesive with Acetone, and adhere bumpers using
Super Glue (cyanoacrylate).
