    FES...a means to an end

    I don't know what everybody's take on this is...but this morning, I put my stim unit on my quads. With a walker, I was able to stand.

    Now this to me looks like a viable means of making many, many people independent of their wheelchairs. Not a decade from now....NOW.

    Now I know that there are commercial "FDA APPROVED" walking "solutions" out there. Buy they simply cost too much and therefore aren't practical for everyone in the community.

    What is a stim unit except a DC current loop? They sell stim units on TV for $49.95. Why should we pay $10000 for an FES bike?

    I want an inexpensive, practicle way OUT of the wheelchair. Braces don't do the job, they are too bulky. NOW.

    OK, so I talk to my orthotics dude this morning, right? I'm looking for a a lock which will allow freedom in the knee joint, i.e. I want to lock the brace at 5 deg, 10 deg, 15 deg from the locked position and have freedom to move my leg. Why??? Because I want to TRY to lock my legs and promote recovery, while at the same time having the protection of the brace so as not to fall over.

    What answer do I get? "That doesn't exist." Hmmm. That's interesting...I wore a pair of braces at Dr. Bohbott's in France which could do this. He sent me a fax with the manufacturer of the locking mechanism. I want to have my braces fit with them.

    But of course, that lock doesn't exist.

    OK, "Sir, can you make the holes bigger in the brace so that I have some freedom?" I'd be skirting my responsiblity.

    Does anybody have a pair of braces with locks that provide some degree of freedom in the knee joint?

    Eric, I've been trying to find someone who maybe has come up with a new design for leg braces. All I can find is what was availble 30 years ago. It seems that by now something more attractive and lighter would have been invented. I outgrew mine years ago, so I cut them off below the knee and hopped around with a walker, good exercise but not practical for getting around from place to place. Then I broke my left femur in half exercising, so i haven't tried anything with braces in years, but am ready to go back to a long leg brace, and like you would want the knee locks to be adjustible for tension. I haven't called anyone in my area yet, but plan to do so soon. I'll let you know what I find.

    Problem is

    The Cheap Stim Units like the ones on TV Don't have enough power and therefore will not work for most SCI people. With a good FES bike, there is plenty of power and it is able to put variable resistance against the muscles and therefore build bulk, something you just can't do with a cheap stimulator. FES is different from just Stimming muscles, it is hitting the muscles with Voltage in a sequence to make the legs do meaningful work and that is to pedal a stationary bike. This also requires a biofeedback loop so as to not overwork the muscles and cause damage since most with sci have no sensation. It is pretty complex and not really mass produced and I can imagine Liability insurance is not cheap due to all these lawsuits these days, thus the high price. Curtis

    Hmmm. I'll check into what you say about various voltage applications. My understanding of fatigue is somewhat different. When a given amount of current is applied to the muscle, the amount of strength which I get peaks after several contractions. Then, as the muscle is used, it begins to fatigue. The strength of the contraction lessens until the muscle cannot contract any longer with the same current applied to the muscle.

    I ordered a book which dicusses FES for both innervated and deenervated muslces (which I was told wasn't possible!) I'll let you all know what I find.

    Hi guys,
    I've been having the same problem. I use a full length caliper on my left leg, which breaks allowing me to bend my knee to sit down, but I have to walk with it locked in place. It's starting to cause a bit of back pain and I've been trying to find something that will allow me to lock the knee at, say, around 10-15 degrees. The orthotics guys I go to keep telling me that there's nothing available.

    The neoprene braces that athletes use to support their knees have adjustable hinges so what's the problem? Grrrrrrrr. I mean, come on. We can put a man on the moon but we can't come up with an adjustable leg brace?

    Perhaps we need to put our thinking caps on and come up with one ourselves.

    That's EXACTLY what I was looking for. I know they exist, because my brace in France had one. I'll let you know what I come up with...

    Well...Articulations for knee and ancle joints do exist. If I can't get knee and ancle articulations here in the US, I'll go back to France and get them.

    Braces

    Eric Texley wrote : I had a pair of braces made in

    I am interesting in this because I live in Belgium
    and the braces here are made with parts off a German firm Otto BOCK who has an almost complete
    monopoly position in the BENELUX and many other
    coutries but the locks are not so safe and indeed
    there was little or no change over the last decades. Is it possible to post the addres off the
    French manufacturer on this forum or if not I will
    give you my personal e-mail addres.
    Thanks,
    Tshombe.
