ORIGINAL POST
Hi Listmembers,
I have a smaller lady with post polio and genu-recurvatum with valgus
deformity and a fused (triple arthrodesis) ankle. She's asking about an
electronically activated joint that will work with her locked ankle.
Is there an electronic stance control KAFO that can handle the deformity
and work with no ankle motion? I know that the Horton joint can accommodate
both, but the patient says she would prefer electronic. Thank you! Randy

As your note presents, your candidate is as you say 'smaller'. Most all of
the electronic SCO's are quite large and bulky, (and you may want to check
as I believe the L-coding has been deleted for the electronic versions). The
Fillauer SPL-2 is a mechanical version SCO that can be utilized as a KO or
KAFO version and can be used with ANY style ankle with single or double
sidebar configurations. The joint has several standard features Manual
locking, Free motion (Stance control disabled) to use a bike or while
driving, a 15 degree security stop and automatic Stance control all
activated from the custom position able Satellite control unit.
Many SPL designs actually use a double sidebar to control the recurvatum
moment and then a single (lateral)ankle joint (in your case as you
described), double action locked in whatever position that accommodates her
ankle fusion.
Here is a link to the joint, functions and benefits;

I hope that I have offered a possible alternative for your patient
candidate. If you have further questions, let me know.
Otto Bock has an electro-mechanical stance control joint. It is very bulky
though. One of my pt's was a Beta tester and loved it.
I'm a polio survivor with all the problems that you
have listed for this lady patient of yours. Just a suggestion from
someone who has walked in this lady's shoes for many years........I would
really think long and hard before trying to put some sort of electronic KAFO
on your patient that will Work for her with the type of deformity
you have listed here. I personally doubt if you will be able to fit
or accommodate her needs. I've worn KAFO's on both of my legs for
yearsand I fully understand your interest in doing the very best
for your patient but sometimes all of your good intentions could be heading
down the wrong road.
Otto Bock has a few stance control models that could work. Call Otto Bock's
professional services, they can help.
Look into the E-mag active from Otto Bock.
There are only three that I am aware of. E-MAG Active and Sensor Walk by
Ottobock and the E-Knee by Becker. All three will work without ankle
motion. The E-MAG is the smallest but has poor reimbursement. Both the
Sensor Walk and the E-Knee are large by comparison and only have L2999
designations by PDAC.
The E-MAG and E-Knee require no knee flexion moment at terminal stance to
unlock. The Sensor Walk does not.
The E-MAG requires full extension of the orthotic knee joint (5, 7.5, or 10
degrees flexion, depending on joint angle you order).
The E-Knee allows for the user to have knee flexion at Initial Contact and
will block knee flexion in 8 degree increments. The Sensor Walk allows the
same but at any angle of knee flexion.
No offense but you may want to send her to Marmaduke Loke in San Diego area
to discuss a system for her. He has done some amazing things! Maybe you
would consider working with him
