Abstract Summary
When computing ankle joint complex power using inverse dynamics, should you cut holes in the shoes to allow for skin-mounted motion tracking markers? And how important is consistency in marker location on the foot? We addressed these two important questions in walking and running. Our results suggest that you may want to put away the scissors (i.e., forego cutting holes in your footwear), and instead pick up a Sharpie® pen, based on the fact that we did not observe significant differences in joint power when comparing shoe vs. skin-mounted markers, but we did observe significant differences due to the precise location of markers on the foot.
