Instructions for Use (R-720-175, Rev. D)
English
Due to the posterior placement of the Kinterra’s ankle pivot point, changes to the
plantarflexion and dorsiflexion resistance settings will be most noticeable to the patient
when they are walking on slopes, not level ground. Adjustments of the resistances are
best done on a gradual slope as a final step in dynamic alignment.
Start the dynamic alignment by setting the heel stiffness first, to optimize the heel strike
to mid-stance motion before proceeding on to adjust the dorsiflexion adjustment.
Adjust plantarflexion resistance to dampen heel strike. If a foot slap is noticed or heel
strike it too abrupt, increase the “PF” resistan
ce. If the heel is too firm or the knee is
buckling at heel strike,
decrease “PF” resistance.
Dorsiflexion
“DF” resistance is adjusted to control the advancement of the amputee over
the foot. If the patient feels
they are walking “downhill”,
increase DF resistance. If the
effort to advance over the foot is challenging for the user,
decrease “DF” resistance.
