I was going to comment "This research was commissioned by the Ministry of Silly Walks", but Monty Python and that sketch are specifically mentioned in the paper as inspiration! I have a slightly silly walk I use. I call it the ASIMO walk. It's a deliberate walk with the knees very slightly bent in the manner of an ASIMO robot, with an eye to taking the load off my knee joints (which bear the brunt of it if I lock out as normal) and strengthening the stabilizer muscles around my knees, to better preserve the joints as I age. Recovery from knee replacement is a stone cold bitch and I'd rather not endure that if I can avoid it.
