Travel Tips Part 3: Hotels and Homes

Let me start this post by putting you in the right frame of shoe.

It's often a bit intimidating for new amputees to leave the safety (and fantastic bedside table service) of the hospital in order to venture home and begin adapting to independent life again. This is quite normal.

There's a LOT to figure out; how to carry a cup of coffee on crutches for example or how to go up and down a winding staircase. It takes practice to navigate the most familiar of environments, let alone one that's entirely foreign.

Now imagine what it's like to be asked to spend the night in a hotel room or someone else's home for the first time (post surgically). How about camping? In a tent? On the side of a rocky mountain somewhere?

Hey, no problem!

Those pesky midnight trips to the bathroom:

In the past I tried traveling with collapsible hiking poles in lieu of crutches to get me around the room in the dark after I'd taken my leg off.

I thought it made sense; poles are light, compact and easy to pack in a suit case or strap to the outside of a backpack and might provide a little stability to my hopping in the middle of the night.

This proved to be quite dangerous. More than once, I very nearly took a header into the wall having a false sense of stability and the poles themselves would trip me up on unexpected lamps or desk chairs.

Solo hopping was no better and using a cane didn't work either. I didn't exactly have the best balance at 3am and the cardio woke me up a little too much.

I eventually came to the realization that, as much of a pain as it can be in the middle of the night, I just had to get used to putting that prosthesis on.

Do it a thousand times a day, in the dark, upside down in a tent, under water, in zero gravity and buried in a snowdrift until it becomes ultra-fast and completely second nature. It's really the best way to be safe and stable and let's face it, when you're camping you really don't have a choice.

I also find it helpful to keep a small flashlight/headlamp next to the bed. I'm less likely to run into an unexpected suitcase or lamp and the first few steps on a hastily donned leg aren't always completely stable.

Tricky shower configurations:

The "lip" on the bottom of a shower door can be a real challenge. Sometimes it can be 6 inches high and made of brick, a difficult obstacle to shimmy over on a wet surface. Recessed showers are even worse.

Probably the easiest and safest method with any shower is to leave the leg on until the last minute. I release the suspension and keep my leg in the socket until I'm ready to step out of it, having used my good leg to step in to the shower stall or tub.

Believe it or not, in all the assessments I had from care advisers, not a single person said "umm.. it's not hard dude, just keep your leg on until you're inside" so this was revolutionary to me when I figured out how to do it safely.

The real trouble comes when it's just not practical to do this. Sometimes a tub side is far too wide and the stance gets unsafe. Other times, having the leg that close to the water would mean all the fabric parts of my liner and suspension would get wet, making for an uncomfortable day.

Tub configurations with wide sides can be tricky but as long as it's easy to reach both tub sides without getting off balance, I can usually just sit on the edge and twist in.

The real trick comes in getting out when you're soaked. The sides can be treacherous and there's very little friction so using a few dry hair towels for grip is a handy trick.

This still leaves recessed showers, large bricked in stalls (common in campgrounds & airports) and other tricky configurations where the liner or suspension would get wet.

To solve the problem, I use the desk chair from the hotel room and push that up to the shower door. I walk or crutch to the chair, sit down, put my crutches or prosthesis aside, place my foot inside the shower stall and stand up. Easy and safe.

So there you have it!

You really don't need anything special (mobility tools, shower aids, etc) when staying somewhere new. In fact, forming a reliance on them at home may cause stress when they're unavailable. Just arm yourself with a few extra ideas for adaptation and figure out what works for you.

Then again, maybe I'm the wrong person to ask about "disability aids". I like to believe that I could survive indefinitely, hundreds of miles from civilization (if such a place even exists anymore) with nothing but a makeshift knife and fantastic looking beard...

Leg-a-versary!

Today, March 19th, is my Leg-a-versary.

It's hard to believe it's only been one year since I received this leg. I still can't believe it took so long to get one but at least I can proudly say I put it to the test once I did. Here's a few photos from my leg's first year:

Thought-controlled prosthesis

Rome, Italy | AP
"A group of European scientists said Wednesday they have successfully connected a robotic hand to an amputee, allowing him to feel sensations in the artificial limb and control it with his thoughts.

The experiment lasted a month, and scientists say it was the first time a patient has been able to make complex movements using his mind to control a biomechanic hand connected to his nervous system.

'The approach we followed is natural,' Rossini said. The patient 'didn't have to learn to use muscles that do a different job to move a prosthesis, he just had to concentrate and send to the robotic hand the same messages he used to send to his own hand.'

It will take at least two or three years before scientists try to replicate the experiment with a more long-term prosthesis, the experts said. First they need to study if the hair-thin electrodes can be kept in longer.

Amp-a-versary

Today was my amp-a-versary and the last day of Legadon.

I've come a long way from that hospital bed one year ago and I couldn't have done it without the incredible support of my family, my friends and my entire recovery team.

To celebrate our year together and to thank you for participating in my recovery, I've compiled a short video along with this list:

November 2008: the surgery.
December: learned to pop-a-wheelie in my chair.
January: first one-legged indoor climb.
February: crutch-climbed Mount Coolum.
March: first prosthesis, first abseil/rappel ten days later.
April: first outdoor rock climb.
May: first single-fin SCUBA dive.
June: first ice skating attempt on prosthesis.
July: first cycling attempt on prosthesis.
August: Bridge to Brisbane 10k.
September: new socket, pack training.
October: climbed Mount Kilimanjaro.
November 2009: Traded in wheelchair for snowboard...

Bratz

This email made my week!

Hey Mike,

I thought you might get a kick out of this. My daughter had her third birthday party this weekend and got a Bratz doll. Since you're probably not up on your girl toddler toys, Bratz are super popular with the under ten crowd. The doll comes with all these little designer clothes that you can change the doll in and out of.

So when I was helping Wynn change the shoes of her Bratz doll, I realized it doesn't actually have feet but what looks like a stump with a prosthetic shoe that you change. It made me think of you. Who knew that you were similar to a Bratz doll? You too would be very popular with little girls if you would consider wearing sparkled high heels or fancy tall boots. You may want to consider a career change.

Anyways, I hope all is well with you!

Climbing at Kangaroo Point

Four weeks ago, on March 19th, I set a goal for myself that I would do my first outdoor rockclimb in one month.

Today I achieved that goal with the help of some very good friends. It was great to be back on the rock and even better to make it to the top!

Climbing on the prosthesis was similar to what I'd expected it to be but I learned a lot that I hadn't expected. I've been visualizing the actions and trying to work out where my advantage points would be as well as what I'd need to overcome.

As MJ commented in an earlier post, imagine standing on a toe that never gets tired. This was great and it did provide a neat little perch when I could find a secure enough ledge to stand on.

Trouble was, the super flexible foot inside the shoe would also flex a little too much, twisting out of cracks when I didn't expect it, or twisting sideways off the tiny micro-edges of a sheer rock face without providing me the feedback that it was about to let go.

The foot itself is also a bit more narrow than a real foot, so putting my faith in the side of the climbing shoe was no longer an option.

I did like the fact that my toes didn't get sore in my left foot. This was fantastic when I was climbing a narrow crack. No big toe to start complaining!

A lot of my challenges today came down to a lack of sensation.

When you climb, you feel the rock through your feet a lot rather than looking for holds. A bit of pressure through the toes usually provides enough feedback to let you know whether you're going to stick or slip before transferring all of your weight to the hold.

This was definitely lacking on my left side, leaving me the challenge of working out a new system on the fly. More than once, I put my faith in a foot hold that proved to be a mistake. This new "spidey sense" will develop with more practice.

All in all, we had a great day and I had a good sense of accomplishment. I learned a LOT, found a few hitches that I'll have to work out, but eventually, I reached the top of the cliffs.

I'm happy to report that a lot of my mishaps on the cliff came less from prosthetic troubles and more from:
a) being out of practice
b) lacking proper climbing form
c) lacking confidence in my hands/shoes

... and all of that comes from not having climbed in six months. This is great news because I can easily overcome all of those by getting more practice in.

Looking forward to getting back out there for another try very soon! I've got a new form to work out so these are exciting times.



Lisa approaching the top!



Matt taking the hard road; this sheer face really shows his skill.



Mike and Mel, she's the best!

Advances in Prosthetic Legs

Another article re-post I'm afraid, but this has been on my mind a lot lately.

I spoke with the Prosthetist who's building my first leg the other day and I'm told I'm getting one of the most advanced systems they've ever assembled at this hospital. They're all very excited to finally have someone eligible to receive these components as much of it is based on physical fitness, age and suitability.

The components I'm getting are coming from Ossur, an Icelandic based prosthetics company renowned for its unique running feet.

I'm sure you've probably heard about the incredible story of Oscar Pistorius, the double below knee amputee who very nearly qualified for the South African Olympic team this past year and instead took home the gold medal in the 100, 200 and 400 meter Paralympic events in Beijing. Oscar runs on Ossur's Cheetah Flex-Foot system.

In doing some research on Ossur and the components I'll be receiving, I came across this article in the Spectrum (again). It's incredible the advances they've made in these limbs.

Read the article here: http://www.spectrum.ieee.org/nov05/2189

I'm set to head in for casting on Friday with any luck. From the cast, they'll mold by socket and begin assembling the suspension system. The wait is excruciating but I'm glad the process is finally underway.

The Revolution Will Be Prosthetized (IEEE Spectrum)

This is seriously cool! Imagine having a prosthetic arm and still being able to feel sensations through it like heat or textures. It's one of those cases where the truth is stranger than the fiction, and the truth absolutely blows my mind.

I saw this article in the IEEE Spectrum hard-copy and thought I was going to have to re-write it here word for word until a quick google search found the exact same article online.

"The Revolution Will Be Prosthetized: DARPA's prosthetic arm gives amputees new hope"

A few teaser excerpts:
"...research is part of a nationwide effort to create a neurally controlled prosthetic arm. That arm has been the focus of much media attention, but that focus obscures the truly groundbreaking research typical of the Revolutionizing Prosthetics 2009 (RP2009) program.

The U.S. Defense Advanced Research Projects Agency (DARPA) is pouring at least US $71.2 million into the program in the hope that it will let amputees do what most people take for granted: make gestures, test the water in a teacup, turn a key, even peel the shell off an egg. Words like bionic and thought-controlled have been thrown at the project, but they don’t do justice to the sheer ordinariness of its purpose. DARPA isn’t looking for a superstrong “Six Million Dollar Man” arm; it just wants an arm that moves exactly like a real one does."

Canadian connection:
"In October, a Canadian hospital announced that it had used part of the control mechanism of the DARPA arm to steer regular, nonrevolutionized prosthetic arms in two patients. Simply borrowing that one technology has made huge improvements in commercially available prosthetic devices."
