Goodaye Eric, I'm reading this as "is it", is that right?, thanks, mark

It's kind of an interesting sentence in that, I think, could have the same meaning with both versions. The idea that you could maintain peroneus longus activity with decreased peroneus brevis activity is theoretically possible. You would want to do some experimentation to find out if it really happened. Your research question would be the other version, the question is it.

When I was in podiatry school, when I was waiting at the bus stop with nothing better to do, I would try to individually contract muscles of the lower leg. I can contract my peroneus longus without contracting my peroneus brevis while sitting in a chair. Whether or not it does happen in gait is still a research question.

Probably more than you wanted.
