I was just saying the way the abstract refers to joint movements isn't all that precise. Probably for brevity, but doubtful they emg'd all of them.
One issue I've seen with these types of studies is the difficulty of looking at the vastus intermedius, since it's deep to the rectus femoris.
Also, the 20% they claim for plantar flexion is a lot higher (more than twice) than I've seen elsewhere.
