Right now, Stacey Kozel is walking on the Appalachian Trail - the 2,190-mile stretch from Georgia to Maine that leads hikers over 14 states, five national parks, and enough elevation to equal 16 Mount Everests.

Two years ago, Stacey Kozel was in a wheelchair.

Her hike is the result of hard work, dogged determination, and a revolutionary new technology that allows people with paralysis to move like never before.

This is her incredible story.
