A LOW TECH PROSTHETIC FOR THE OUTDOORS

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

MEET DAVE PARTS IN A PROSTHETIC:

amputees use 1.5 times effort per step compared to able bodied people

but mark can’t join them

higher than the world average

Outdoor magazine recently featured the newest method of rehab for returning soldiers:

socketthe human interface. strapping into the socket means you’re safe and secure

calfoften controls the robotic knee. otherwise usually a pylon

foothelps establish a regular gait pattern. many different styles.

anklesome lock and some are free swinging, depends on if they’re robitic

kneemany different kinds of knee. but they all help the calf free swing

THE WORLD OF PROSTHETICS IS A BUSY AND CONFUSING PLACE. IT’S TIME TO DIG IN

CURRENT SOLUTIONS

2aren’t a complete solution

SO WHAT IS BEING DONE TO HELP?

Three above knee amputees climbed a rockwall using five different prosthetics. Biometric data was collected from the climbs. They also subjectively rated the climbs.

ROCK CLIMBING WITH A PROSTHESIS INTERVIEWS A CLIMBING TASK ANALYSIS

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

on some occasions it would have been nicer if the straight leg was shorter, so the climber has a wider range of motion

Getting over ridges is very difficult, because the straight leg cannot bend, or apply force to assist the climber.

Near the top things can get tiring, because of the deadweight of the leg, combined with the stress on the muscles.

Mike Lagerstrand - va prosthetist“Keep [the prosthetic] as simple as possible”

Patrick Taylor - head of va prosthetics“There is a big need for this”

Rock Rocco - prothetist “You’d probably want a sleeve and suction working”

Andrew Meyer - above knee amputee“An articulated knee would really be useful for me”

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.

all in all, research encompassed over 75 scholarly articles, and 8 interviews.

SOCKET CONCEPTS

DRAWING INSPIRATION FROM ANATOMY

CALF AND KNEE CONCEPTS

FOOT CONCEPTS

Socket comfort is critical, additionaly the socket must become better integrated into the rest of the prosthetic. Aesthetically and functionally.

I began by sketching the musculature of the leg in order to draw from biomorphic inspiration.

The foot needs to be both lightweight and modular, supporting the hiking and climbing activities with equal proficiency.

The decision on whether or not to include a knee was critical. The calf also controls leg adjustment

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 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

The Everest Leg

the difference in climbing and hiking height helps increase range of motion and optimize both activities

Free swinging knee locks for climbing with a simple allen wrench.

Leg height is fully adjustable with a double pushbutton for safety

Laminated plastic helps protect vulnerable carbon fiber, and lengthen socket life

New slim profile air valve protrudes less underneath clothes

Safety rope helps keep the leg attached, both while climbign and hiking

foot has a rubber outsole, no shoe required.

Foot rotates 180o to climb, reducing the stress on residual limbs

38% CHANGE IN HEIGHT

Climbing freely is no longer a problem with a fully articulating knee. Lose that shoe deadweight too.

When it’s time to climb, get out an allen wrench and tighten the knee to lock it into a straight position

by pressing down on both sides of the calf, the leg will shrink 7.5 inches.

SO HOW DOES IT WORK?SO HOW DOES IT WORK?

The leg height adjusts with a retractable steel pin. The pin has a shear strength of over 1ooo pounds which means the user is safe at any height. with a button on each side, there won’t be any accidental presses.

A foot that pivots 180 let’s the user hike on a full foot and climb on a short one. This reduces the length of the lever their weight is resting on, increasing efficiency and reducing stress.
