A LOW TECH PROSTHETIC FOR THE OUTDOORS Prosthetics are getting more and more high-tech. What about a low-tech solution for both rock climbing and hiking?

LETS TALK ABOUT AMPUTEES
MEET DAVE He is one of over 1,000 soldiers returning home with a missing limb
in fact
of 500 amputees surveyed in a study:
57%
experience pain while wearing a prosthesis
70%
of all amputees surveyed do zero or one of the activites they did before the amputation
the human interface. strapping into the socket means you’re safe and secure
calf
often controls the robotic knee. otherwise usually a pylon
knee
many different kinds of knee. but they all help the calf free swing
of all amputations occur below the waist
30%
PARTS IN A PROSTHETIC: socket
“it was a big adjustment” Andrew Meyer, active above knee amputee
foot
helps establish a regular gait pattern. many different styles.
ankle
some lock and some are free swinging, depends on if they’re robitic
depression
4x
higher than the world average
amputees use 1.5 times effort per step compared to able bodied people
SO WHAT IS BEING DONE TO HELP? Outdoor magazine recently featured the newest method of rehab for returning soldiers:
ADVENTURE

CURRENT SOLUTIONS
won’t bend at the knee
aren’t a complete solution
are very heavy
THE WORLD OF PROSTHETICS IS A BUSY AND CONFUSING PLACE. IT’S TIME TO DIG IN

A CLIMBING TASK ANALYSIS Starting the Climb is not an easy task, it’s mostly arms in the beginning since footholds are limited.

INTERVIEWS

Three above knee amputees climbed a rockwall using five different prosthetics. Biometric data was collected from the climbs. They also subjectively rated the climbs.
“You’d probably want a sleeve and suction working” Rock Rocco - prothetist
“An articulated knee would really be useful for me”
Getting over ridges is very difficult, because the straight leg cannot bend, or apply force to assist the climber.
Andrew Meyer - above knee amputee
all in all, research encompassed over 75 scholarly articles, and 8 interviews.
many modern prosthetics today are still fitted to the users with old fashioned techniques such as hand sanding, sewing, and lamination. While most of the body is prefabricated, all of those operations are drawn of custom measurements. The socket is always custom made, and there is no such thing as a one size fits all prosthetic right now.
Near the top things can get tiring, because of the deadweight of the leg, combined with the stress on the muscles.
on some occasions it would have been nicer if the straight leg was shorter, so the climber has a wider range of motion

SKETCHING
CALF AND KNEE CONCEPTS
SOCKET CONCEPTS
The decision on whether or not to include a knee was critical. The calf also controls leg adjustment
Socket comfort is critical, additionaly the socket must become better integrated into the rest of the prosthetic. Aesthetically and functionally.
DRAWING INSPIRATION FROM ANATOMY I began by sketching the musculature of the leg in order to draw from biomorphic inspiration.
FOOT CONCEPTS The foot needs to be both lightweight and modular, supporting the hiking and climbing activities with equal proficiency.

REFINEMENT Validation was conducted with three different prosthetists, as well as an active above knee amputee. Initially thinking the Heavyweight would win, the Lightweight caught me by surprise.
THE HEAVYWEIGHT
I thought the Heavyweight would win out in validation. Not Quite... THE MIDDLEWEIGHT
THE LIGHTWEIGHT
HITS
HITS
valve placement
simplicity
fabric pocket for tools
shock absorber
weight
good suspension
MISSES too heavy very complex roll cage might not convert to hiking easily
“Seems too heavy to me”
Mike Lagerstrand - va prosthetist
HITS
socket bumper
aesthetically a winner rubber overmolded socket

MISSES
large height change
too much mass
MISSES
height diminished by shock
not as visually exciting
offset shock absorber
missing a failsafe
too complicated
no shock absorber
“This one doesn’t seem too solid. It’s very complex” Rock Rocco - prothetist
“I like it a lot. It seems very simple and practical”
Andrew Meyer - AK Amputee

REFINEMENT The refinement process consisted of iterative 3d modeling based off of rough hand sculpted models. These models were then used to generate full scale plots in order to test human factors and scaling.
3D and 2D refinement occured in parallel, with a lot of jumping back and forth

HIKE
The Everest Leg Laminated plastic helps protect vulnerable carbon fiber, and lengthen socket life New slim profile air valve protrudes less underneath clothes
Free swinging knee locks for climbing with a simple allen wrench.
Leg height is fully adjustable with a double pushbutton for safety Foot rotates 180o to climb, reducing the stress on residual limbs
7 inches
the difference in climbing and hiking height helps increase range of motion and optimize both activities
Safety rope helps keep the leg attached, both while climbign and hiking
foot has a rubber outsole, no shoes required.
