How We Developed the LUKE Arm Interface

Luke Arm InterfaceImagine a state-of-the-art prosthetic limb designed to quickly integrate with your own body, a limb that could give you the capability to grasp a small paintbrush or a pair of chopsticks. Now imagine that limb with a traditional prosthetic socket interface, one that uses friction and pressure to secure it, compromising its function and comfort. This was the problem faced by the developers of the LUKE (Life Under Kinetic Evolution) Arm. The LUKE arm needed an interface as elegant as its design. That’s where we came in.

Approved by the FDA in 2014 and in development for nearly a decade, the revolutionary Luke Arm was designed by Segway creator Dean Kamen and his company, DEKA. While the device’s intuitive nature and ability to execute extremely fine and flexible movements is groundbreaking, the challenge of human integration presented its own unique challenges. Traditional socket designs act more as a “cup” to hold the limb allowing the bone and surrounding tissue to move inside it. The result of this “disconnect” is the loss of skeletal integrity with much-wasted motion, not to mention the discomfort caused by constant friction. How would the LUKE interface replicate the skeletal motion and nearly seamless extension needed to work this highly advanced prosthetic device?  Continue reading “How We Developed the LUKE Arm Interface”

Celebrating the Milestones – Dancing, Walking, and Running for the First Time

Next Step Celebrating MilestonesIf you have recently experienced the loss of a limb, it can be difficult to envision yourself and what your life will look like in a month, or a year, or even tomorrow.  You know there are incredible amputee athletes out there pushing the limits of human endurance – climbing mountains, sprinting, or competing with thousands of elite athletes in the Paralympics. Perhaps those stories inspire you; maybe they’re just hard to relate to. Most of us are not world-class athletes or driven to pursue extreme athletic accomplishments.  Continue reading “Celebrating the Milestones – Dancing, Walking, and Running for the First Time”
