General Discussion / BIID
« on: June 18, 2008, 07:12:42 AM »
I just came across a article about a young father who deliberately froze his own leg in order to have it amputated. He has BIID (body integrity identity disorder). I think, fair enough, he has a mental disorder, there is no shame in that. But, obviously he fell through the cracks and wasn't diagnosed or treated (or treated properly). Its sad.
Part of me feels sorry for him, and part of me just wants to give him a slap. He says he's happy now and his marriage is doing well.

General Discussion / Alpha Max liners
« on: June 11, 2008, 12:05:59 PM »
I got 2 Alpha Max gel socks ages ago and never really used them for some reason and just kept using my Alpha Spirit socks instead. I decided I best use them and I seem to get a red irritated band across my leg where they stop.
I forget if I had these sort of thing when I first started using the Alpha spirit liners so maybe it is just a breaking in period as the Alpha Max socks are a bit longer then the other ones so they end where sicks has not had a liner touch before. As far as I know the only difference between the liners are that the Max liners have a more durable fabric on the outside.

Monkeys have been able to control robotic limbs using only their thoughts, scientists report.

The animals were able to feed themselves using prosthetic arms, which were controlled by brain activity.
Small probes, the width of a human hair, were inserted into the monkeys' primary motor cortex - the region of the brain that controls movement.
Writing in Nature journal, the authors said their work could eventually help amputees and people who are paralysed.
Lead researcher Dr Andrew Schwartz, who is based at the University of Pittsburgh School of Medicine, said: "We are beginning to understand how the brain works using brain-machine interface technology.
"The more we understand about the brain, the better we'll be able to treat a wide range of brain disorders, everything from Parkinson's disease and paralysis to, eventually, Alzheimer's disease and perhaps even mental illness."
natural movement
With the probes inserted into the monkeys' motor cortices, computer software was used to interpret the brain's electrical impulses and translate them into movement through the robotic arm.
This arm was jointed like a human arm and possessed a "gripper" that mimics a hand.
After some training, two monkeys - who had had their own arms restrained - were able to use the prosthetic limbs to feed themselves with marshmallows and chunks of fruit.
The researchers said that the movements were fluid and natural.
The monkeys were able to use their brains to continuously change the speed and direction of the arm and the gripper, suggesting that the monkeys had come to regard the robotic arm as a part of their own bodies.
The success rate of the experiment was 61%.
Dr Schwarz said: "In our research, we've demonstrated a higher level of precision, skill and learning.
"The monkey learns by first observing the movement, which activates its brain cells as if it was doing it. It's a lot like sports training, where trainers have athletes first imagine that they are performing the movements they desire."
He said the research could eventually benefit the development of prosthetic limbs for people with spinal cord injuries or for amputees.
He said: "Our immediate goal is to make a prosthetic device for people with total paralysis."
"Ultimately, our goal is to better understand brain complexity."
Commenting on the paper, Professor Paul M Matthew from the Hammersmith Hospital, said: "The challenge of interfacing the billions of nerve cells in the brain that control the full range of limb movements directly with a mechanical prosthesis has seemed impossibly difficult.
"However, this important paper confirms that the brain controls movement just by planning where to go, rather than by directing individual muscles how to make the limb get there.
"The study shows that fewer than 100 tiny electrical signals generated in the specialised area known as the 'motor cortex' can command even complex arm and hand movements.
"This moves the day when patients disabled after spinal cord injuries or amputations can use brain-controlled bionic limbs from the realm of science fiction towards science fact."

General Discussion / College Park feet
« on: May 26, 2008, 04:31:24 PM »
I was at the limbfitter today (its quite a coincidence that you replied today robogirl!). He is steering me towards College Park feet.
Namely the Trustep:

the Venture

Anyone try any of these? (I may have asked this before, sorry if I am repeating myself...)

What about the Onyx?

I namely need the foot for everyday and fairly hard manual labour, and some uneven ground.

General Discussion / RSL Revolution foot
« on: May 09, 2008, 09:49:33 AM »
I believe I may have mentioned this in the pas but has anyone have any experience with the "RSL Revolution", or the "variflex" foot? I can find some info on the Ossur page on the variflex but can't really seem to find anything on the RSL Revolution, although I did find a 'Revolution Range" on the Freedom Innovations website but nothing was called the 'RSL'...

I've been talking about getting a new leg for ages and even got two quotes. At the end of the day I did nothing and now I need to have thew quote revised. I do want to get the leg made as my current one must be 6 years old by now and I am wearing 6 cottons socks with it.
One thing though. I seem to need more padding than the 'normal' amp. I still get a bit sore even with 6 cotton and 1 gel liner and if I ever wear less socks I feel pain on the end of the leg. When I go from 1 gel and 6 cotton down to 1 gel and maybe 1 cotton wouldn't it be fairly painful because of less padding?

General Discussion / Soldiers back from Iraq
« on: April 22, 2008, 05:58:43 PM »
I found this page by accident while looking for some light entertainment on the web.

Light entertainment this isn't.

The link below will take you to portraits of soldiers back from Iraq. It appears we have more and more people who qualify to join our little club. I'm not trying to start some pro VS anti war argument.

General Discussion / Army captain loses his leg on Cresta Toboggan Run

Army captain loses his leg on Cresta Run

By Stephen Adams

An Army captain survived a six month tour of Iraq unscathed only to have his leg torn off attempting the famous Cresta Run in Switzerland.
The Cresta Run, where Captain Bernie Bambury crashed
The Cresta Run is so fast that tobogganists must control their approaches through the turns or risk being flung out of the ice gully

Captain Bernie Bambury, 32, lost his right leg below the knee after he hit a marker post at a speed of up to 80mph on the 4,000ft-long tobogganing course in St Moritz. His leg was shattered and severed hundreds of yards from the finish.

But the brave soldier, from 4th Battalion The Rifles, completed the run before asking friends: "Is my ankle broken?"

He then heard the horrifying reply: "It's not broken, it's gone."

The Army officer underwent nine operations by medics who tried to sew the limb back on but Capt Bambury was told it might take two years for him to walk again and he was unlikely to regain full mobility. As a result he gave the order for surgeons to cut it off, preferring the certainty of recovery with a false leg.

Capt Bambury, who is based at Bulford in Wiltshire, said: "The overwhelming balance of medical advice was that amputation and a prosthetic limb would give me the best prospects for the rest of my life and the swiftest return to duty.

"Keeping my foot could have taken up to two years to succeed with a minimal chance of success. I am looking forward to starting my rehabilitation."

He is now at the Headley Court military rehabilitation centre near Leatherhead, Surrey, which has gained a strong reputation for helping those with multiple injuries and fitting soldiers with prosthetic limbs.

A Ministry of Defence spokesman said: "This was a tragic accident and Capt Bambury has taken a brave decision on medical advice to amputate his foot. We hope he is able to make a swift recovery and wish him all the best for his rehabilitation at Headley Court."

The Cresta Run has a long association with the British Army, being created by Major WH Bulpetts and Caspar Badrutt, owner of the Kulm Hotel in St Moritz, in 1884.

Since then many officers have taken the opportunity to try their skill at the purpose-built course, which drops by 514ft in altitude over its 3,978ft length through the hamlet of Cresta and includes gradients steeper than one in three.

It is so fast that tobogganists, who ride their sleds head-first, must control their approaches through the u-shaped turns or risk being flung out of the ice gully at high speeds.

Women are not permitted to ride the run, which is maintained and administered by the St Moritz Tobogganing Club, better known as the Cresta Club.

It is a British club but its members now come from all over the world.

Swearing parrot fitted with false leg

George the parrot has not had a good night's sleep for 18 months, since he lost his leg when a wild animal attacked him in his aviary.

The African Grey parrot, who has usually has a very limited vocabulary, has even been heard to cry out `bloody hell' in frustration at balancing on one claw.

But an expert at the University of Salford fashioned George his own tiny prosthetic device. Dr Glyn Heath, of the university's School of Health Care Professions, is a specialist in creating prosthetics for animals but said this was the first time he had made one for a bird.

George nibbled it, he tossed it aside, he hung from the top of his cage and looked at it, and then ... he ate it.
