Stepping back again from research updates and the news . . .
Last year at this time I was recovering from a broken leg (not from a fall - a post for another time) and beginning to see some quadriceps return. My newest video shows definite progress since then. I'm using Allards modular braces, essentially Ankle-Foot Orthotics with a knee support on one side. These are minimal knee braces. I've also been able to raise the walker slightly. Neither the lightweight bracing nor taller walker would have worked until recently. Very good signs.
Oh - and in this video, I'm walking against a strong wind. Not an easy task!
