An inspiring story from Oandp.com, a website that covers the prosthetics and orthotics community:
Thirty-six years ago, Kevin Johnson lost his right leg below the knee in a combine accident on his family's farm in Ohio. As a teen, he avoided "painful" prosthetics and used crutches to get around. But he knew that was not a good long-term solution. He eventually found a prosthetic leg that worked well enough to support an active life. Johnson's work involves operating bulldozers and piloting helicopters, and he also races motorcycles and ropes cattle. When the prosthetic broke, as it did often, he used a welding torch and duct tape to fix it.
By the end of 2007, the prosthetic leg was broken beyond repair. Johnson got in touch with WillowWood, a prosthetics company in Ohio that was looking for amputees to test technology being developed for military veterans: a prosthetic system that features vacuum pressure, intelligent controls and phase change material. He was the perfect test patient, offering developers valuable feedback and pushing the leg to its limits.
The result: A high-performance prosthetic leg that fits better and is far more comfortable than its predecessors, thanks to the PCM-infused liner that absorbs heat and reduces perspiration and skin irritation.
