Cerebral Palsy maybe/maybe not

Two joggers and a marathoner could not get halfway through these tests. EMG was continuously on with little rest intervals if any. Here we see a jogger at level 5 only able to crawl around the room. Just getting across the camera view was impossible for him. Despite his crippling energy state, he did crawl well.

Cocontraction. Swing phase despite being in a crouch, barely had any knee angle change. Toe walking was universal and early in onset in all our subjects. In later detailed review we did see our 6 th wheel at play. These are not just normal people, they are athletes whose expectation in things physical is excellence. Whatever they do we must assume is the best choice of what is available to them.

The disability was exhaustion. Other studies that only restricted various joint ranges of motion had no equal to this.

We were looking at a solution that all of our subjects immediately found. It Was some kind of built-in plan B. Plan B – for what?

Advancing in the absence of momentum . We all do this when we ascend steep stairs. Our eccentric walking – an evolutionary masterpiece – drops back to concentric walking. Eccentric energy conservation swaps to concentric stepping which is not involved in passing momentum between alternating pendulums. Walk in deep mud? Concentric.
