Thanks for the help everyone. I believe I have captured everyone’s response below.
Original Question:
I have a 7 year old patient that would like to transition from her passive transradial prosthesis with locking liner to a myo.
She has been wearing the OWW ALL-5133-E liner for several years now and is comfortable in it. She also very
much prefers a locking liner over a self-suspending design.
I was interested in using the Otto Bock 2000 Electrohand for Children but I am open to suggestions.
More importantly my question is: what are people doing in terms of liners and electrodes currently? Is a snap electrode
the way to go or are there other common alternatives? I did not see any snap electrodes on Otto Bock’s site. Would I be able to
use ones from another manufacturer with their system? Any thoughts on this would be appreciated.
Answers:
1) I had exactly this same scenario a few years ago. Motion Control has snap electrodes. The pt and I found them to be more trouble than positive. In the end, we converted to Bock sealing electrodes and cut holes in the Alpha liner to allow electrode to protrude and make skin contact. This worked exceptionally well.
Good luck!
2) Otto Bock now offers conductive silicone in their custom liners. Might work for your client.
3) The snap-on Electrodes are great to use with the locking liner. You can mix ottobock with motion control electrodes no problem. You just have to make room for the snap-on wires within in the socket.
4) I am presently in the same position and am planning on using the snap-ons from Motion Control, which I have successfully used in the past, but would be very interested in hearing any other responses.
5) I'm an german cpo and i prefere for the kids touchpads in combination with an locking-liner.
If you take the hand 2000 , you need also an 7 in 1 controller, and its no problem to take touchpads.
For the 7 in 1 controller you will need a akku-system 757 B 35 ( to program the different modi with the software ).
I have now a kid changing the system from scamp-hand ( Steeper ), cause the scamp-hand is only in sizes 5 + 5,5.
My question : how long is the hand from end of Dig3 to the wrist-joint ?
Maybe the scamp-hand 5,5 is long enough.
You can take any akku-system what works in the electronic level !
For the first time using a myo i prefer the evo-modus.
You should take an eye on the size of the hands an also on all important measures .
With touchpads you have the oportunity to change the places in the socket .
If you want to have more infos, don't hesitate .
6) The system 2000 hand from Otto Bock is the best choice for this age group. The small Bebionic would be the next size in line.
Snap electrodes from Motion Control would work well, but you need to run MC Triad preamps.
Call Gerald Stark, CPO UE product specialist with Otto Bock, he also use to work for Filluar/ Motion Control. He can help you.
7) While the snap electrodes are slick they're also a pain in the butt and they result in a larger circumferential build to accommodate the wiring and the snaps. If you have an old liner of hers that you can experiment with I'd recommend using OB square electrodes with the silicone sealing aprons and then cutting holes in the exact locations of her sites. The holes in the liners will be a little larger than the actual electrodes themselves so that they can self orientate (1.5 x 1 approx. to start). The apron electrodes are nice because they offer a smooth transition when donning/doffing and they also seal the socket shell from any debris or perspiration. You won't have to worry about window edema due to the counter pressure provided by the electrodes and you're still able to use the locking mechanism. I'd also recommend that when you do your modifications that you slightly tighten/reduce the electrode area so that you can accommodate the liner to skin thickness discrepancy. This can be checked when you fit the test socket...after she has worn it for several minutes and the socket with electrodes is doffed a light electrode imprint should remain.
