Hanger Clinic fits first civilian amputee with waterproof X3 microprocessor-controlled prosthetic legs

Austin, TX, June 22, 2013 – Hanger Clinic recently became the first company to introduce the revolutionary Ottobock X3 microprocessor-controlled prosthetic knee to the civilian patient population. 27-year-old bilateral above-knee amputee Cameron Clapp was fit with two X3s on June 7 by a team of Hanger Clinic prosthetists in Oklahoma City.

The result of a collaboration between the US military and Ottobock, the goal was to develop a more durable and intuitive prosthetic leg to help injured service members with above-knee amputations return to normal activities of daily living as well as active duty if they choose.  Features of the X3 include:


·         The first electronic leg that is completely waterproof, the X3 allows for unprecedented contact with water including showering, swimming, boating, fishing and more.

·         An accelerometer and a gyroscope that is able to intuitively tell where a user's leg is in space. These are the same technologies used in Wii™ gaming systems and in adjusting screen smartphones and cameras and allows for a virtually natural gait. That means less worry of a stumble or fall and less concentration needed when on the move.

·         More physical capabilities for the real world than any other prosthetic leg including running, walking backwards, crossing obstacles in a more anatomically correct way, and climbing stairs step-over-step without massive compensating movement an action that previously appeared impossible for those with above knee limb loss.

·         The X3 is 'ruggedized' based on conditions an active duty military member might face and is up to the challenge of adverse and rough terrain.

·         Programmed using a laptop and Bluetooth technology, five activity modes can be set for biking, golfing, driving, etc. and are activated using a key fob-sized remote.  A mute mode is also available that silences all vibration and beep signals of the leg when needed for activities such as meetings, church services, hunting and more.


Clapp lost both legs and his arm when he was struck by a train at just 15-years-old in 2001.  He has worn microprocessor legs for years, but has been limited by the need to remove his legs to shower, to swim, or even to navigate rough weather. 


Clapp says he now feels liberated.  He shared a reoccurring nightmare that he has had for years where he would walk past a swimming pool and accidentally fall in, ruin his prosthetic legs, and never be able to walk again.  Now, he says, he’s looking forward to no longer having that nightmare.
