During my time with heavy long-legged KAFOs (Knee-Ankle-Foot Orthoses), I saw increasing ability and strength over time. I began with locked braces that did not allow any knee flexion. The locks were eventually able be disengaged and later removed altogether. One of the big signs of progress was being able to reliably step up a curb and then back down again without any help. Hopefully these older videos from May 2015 will encourage someone else, too!
