Gait Speed, hip extension, and A New Dawn

Velocity, timing, stance and swing phases, injuries, center of pressure, step width, .... lots of good topics today

This time around we introduce some new literature to provoke some clinical thinking that will inform, amuse and hopefully entertain you.  We also introduce the newest athletic tape to the market, surely someone will rip off our idea, but hopefully they will tag our name to it and help make us famous.
