Walter Reed Patients Receive the PowerFoot BiOM, the Newest and Most Advanced Prosthetic Technology

CAMBRIDGE, MA--(Marketwire - March 28, 2011) - Walter Reed Army Medical Center patients were fit last week with a new bionic lower leg system called the PowerFoot BiOM, announced iWalk Inc., a leader in advanced robotic technology. The BiOM is the only prosthetic system that can actually restore lost muscle function of the foot, ankle and calf for lower leg amputees.

"Nearly all prostheses that are available on the market are passive devices and do not provide the user the muscle function needed to push out of a chair or propel them to walk, climb stairs or negotiate obstacles," said Dr. Paul Pasquina, Col and Chief of Orthopedics of Rehabilitation at Walter Reed Army Medical Center. "What this prosthesis does is substitute for the muscles that are lost for an amputation below the knee in terms of ankle and foot function."

Demonstrating its unique benefits were below knee amputee, Staff SGT. Daniel Lister, and first combat wounded bi-lateral below knee amputee to be fit with the BiOM, SGT. William Leonard. 

"The BiOM does not flatten when I go up inclines. It moves with me naturally so it takes a lot less effort to move about my day," said Lister. "It just makes life a lot easier," he added.

The BiOM replicates the action of the foot, ankle and calf muscles that work together to assist the individual's forward motion when walking. While a traditional prosthesis can store energy and then return it, the BiOM actually replaces energy allowing amputees to walk as normally as possible over all terrain types. 

"Everyone at iWalk is extremely proud to be working with the Department of Defense, and the Veterans Administration in partnership to bring this exciting technology platform to market. After years of research and development, delivering the first commercial units to our combat wounded is a very gratifying event for all of us here. Not only will this platform provide a life changing benefit for our brave service men and women, it will also provide the same quality of life improvement for anyone afflicted with lost muscle function due to injury or illness," said Tim McCarthy, Chief Executive Officer of iWalk.

"It is our hope that that this will not only help our injured service members, but those who have lost a limb all over the globe," added Dr. Pasquina. "This is a good news story we can be proud of," he added.
