Hi all,

I'm wondering what cutoff frequency I should use to filter the marker coordinate and GRF data to do inverse dynamic (calculate knee moment) for a drop-landing movement. Coordinate and GRF was sampled at 120 and 2040 Hz, respectively. I guess the typical cutoff may be 15 and 50 Hz. But I read a few articles (Kristianslund et al. 2012; Bisseling & Hof, 2006) that suggested you should use the same cutoff frequency (15, 15) for both coordinate and GRF to minimize the impact artifact on the knee moment. Any suggestions? Thanks a lot!
