Abstract

The ACL injury mechanism is multi-planar, yet rarely are multi-planar variables examined in an injury risk context. This study examines if multi-planar variables rank individuals more consistently across multiple tasks than uni-planar variables. Forty-four female athletes performed bilateral drop vertical jumps, single-leg hops, single-leg drop vertical jumps and sidestep tasks on their dominant leg. Uni-planar (KM_ab) and multi-planar (KM_nsag) variables of the knee were extracted and correlated between tasks. Participants was ranked according to KM_ab and KM_nsag, and then grouped into quintiles for each task. When variables are consistently ranked across tasks, a movement signature is identified. In total, uni-planar movement signatures were identified more than multi-planar movement signatures. However, both undesirable multi-planar and uni-planar movement signatures were identified in unique participants. Multi-planar and uni-planar variables are both important when screening for undesirable movements.
