Not really following the rules but I like to allow Stunned Maneuver rolls to allow you to move as if unstunned, but you still have all the negatives.
Being an amatuer MMA fighter I can definately atest to being 'stunned' from blows and having the skill to move around and still act.
One of my fellow fight gym members was actually KO'd in a fight he had. He was knocked out for a split second and bounced back up and attempted to take down his opponent. He was then pushed off and kocked out again. He only remembered the first KO, but had the knowledge to fly on autopilot.
