Hanger Clinic patient Patrick Tierney first in world to receive new Kinnex waterproof microprocessor-controlled ankle-foot

Rancho Mirage, Calif., July 8, 2016 – This week, retired priest Patrick Tierney became the first amputee in the world to be fit with the Kinnex, the first waterproof microprocessor-controlled prosthetic ankle-foot.

To hear Tierney and his Hanger Clinic Prosthetist Lee Cardon, CPO discuss the new technology and what it means for Tierney's mobility, watch the following segment from KESQ-TV (ABC/CBS):

About the Kinnex: The waterproof capability of the Kinnex enables users, for the first time, to use a microprocessor-controlled ankle-foot to do things such as walk in a shower, go paddle boarding, or visit a waterpark with their children, to name a few. Using embedded sensors and built-in Bluetooth connectivity, the Kinnex ankle-foot can sync to a mobile app on users' smart phones, allowing for real-time feedback and adjustments for both the user and prosthetist, including heel height adjustments, accounting for up to a two-inch heel height. Users can store up to 100 shoes in the app, and easily wear the shoes of their choosing.

The microprocessor-controlled ankle-foot has a 30-degree range of motion, allowing the user to navigate a variety of terrains, including inclines and declines, while having a uniquely stable and natural walking experience. The Kinnex also allows users to activate an "Apparel Assist Mode" from their app, that when initiated, the ankle locks in the current angle, making it easier for the user to change clothes or footwear.

About Patrick Tierney, the first amputee to be fit with the new technology:  Retired priest Patrick Tierney, 76-years-old, lost his leg below-the-knee in May 2003, as the result of a car accident, but that hasn't slowed him down. Shortly after being fit with a prosthetic leg, he moved from Colorado to Cathedral City, Calif. where he worked at the Betty Ford Center for ten years, and now volunteers his time as a spiritual counselor to those suffering from drug and alcohol addiction. He enjoys working out at the gym five times a week and with the new Kinnex, has aspirations of returning to the ocean and going on a rafting trip down the Grand Canyon.
