Abstract
Knee biomechanics changes under dual task during single-leg drop landing
Highlights
70% of anterior cruciate ligament (ACL) ruptures occur during single foot contact in sport (Boden et al 2009; Olsen et al 2004)
The most important findings of this study were that the maximum tibial internal rotation angle and peak ground reaction force (GRF) increased under dual task conditions
Our hypothesis had five candidate factors that may increase ACL rupture risk, and we show two of five factors increased under the dual task
Summary
70% of anterior cruciate ligament (ACL) ruptures occur during single foot contact in sport (Boden et al 2009; Olsen et al 2004). Single-leg drop landing (SDL) is an assessment method with greater exercise load than VDJ, and studies comparing the two tasks found that knee load is significantly greater with SDL (Earl et al 2007; Harty et al 2011; Nagano et al 2009; Pappas et al 2007; Taylor et al 2016), indicating that it is more suitable for examination of athletes. Studies found that knee kinematics do not differ significantly when healthy athletes perform SDL as a single task compared with VDJ (Ford et al 2006; Wang 2011), suggesting that increasing exercise load is not sufficient to disturb the athlete balance and investigate knee biomechanics under conditions resembling competition; increasing the difficulty of the motion is necessary
