Muscle activity

Does variability in muscle activity reflect a preferred way of moving or just reflect what they’ve always done? In this study it was found that there isn’t always this tight relationship between activity in the muscles and the movement we’re seeing.
“Clearly, locomotion is not as simple as we thought it was,” Foster said. “This decoupling – big changes in movement without corresponding changes in muscle activity – suggests there are other important factors going on and we need to better understand them if we want to reproduce these movements in prosthetics or robotics.”
Hmmmm. thoughts. this makes everything more interesting doesn’t it ?!
