Hello All,
The original question:

> systems listed above. Which of these two products do you prefer? What,
> in your mind, are the biggest differences between the two, as far as
> function goes? How about from the perspective of (patient) user
> friendliness? Has durability been a factor for you with either of these
two systems?

The Responses:
(I'm listing one response ahead of all the others, simply because it is info
that we should all have and be able to use.)
* Here is a link to a comparison of the various MPF currently on the market
on the AAOP Lower Limb Society social networking site.

* Biom has an inline battery as opposed to proprio.
Biom has powered dorsiflexion creating energy in gait.
Proprio can actively go into DF to assist in stair climb and ramps. And has
a rested position.
Biom battery is terrible. 1 day needs 3 batteries on a good day.
Programming is easy.
* The BioM is powered and the proprio is passive motion.
* Can you please forward your replies. I seldom ask of this but I too
inquirer such info as I have fit many Proprio and e'lan ankles.
* The Biom actually actively pushes off at terminal stance to propel the
patient forward. the proprio simply accommodates unlevel surfaces. I had a
proprio on a guy and it had to go back to iceland for repair and it took
several months. I won't fit another one. endolite has the elan and echelon
that are decent options. if the patient is very active though I would stick
to the Biom or look at the Rush foot. The proprio, elan and echelon do not
provide much energy storage/return. fillauer also has one that I saw in
Orlando that was interesting enough that I would at least look at it but I
have never seen it in action other than the guy wearing it at the show.
good luck. by the way, the biom weighs 4 1/2 pounds and extremely bulky and
no way to cosmetically finish. they say the benefit from the active
push-off counteracts the weight (since it is not dead weight) and thje
patient does not remark that it feels heavy.
* This does not directly answer your question but if you have any questions
regarding the Raize microprocessor controlled ankle from Hosmer I would be
happy to address those. I wear the Raize and have fit dozens of them some on
patients that have worn other MPC feet. Please let me know if I can help in
any way.

* Interesting questions. There are fundamental neuromechancial and
neuropsychological issues involved that are just as important, or perhaps
even more important, than the issues you have so thoughtfully brought to
light. I have attached two papers to this effect. The first paper is a
relatively brief (1400) white paper, and the second attachment is a more
lengthy (5800) grey paper. I made up the word grey paper because it has
a method and discussion section, includes a greater reference and is an
attempt to combine clinical art with hard science. I hope you find the
reading interesting and perhaps is some way helpful.
(Note from Warren: If you are interested in reading them, I can forward
copies of these two articles, once I get permission to share them from the
author.)
That's it! Thanks to all who responded.
