Abstract

Quantifying landing technique in sport-specific environments is desirable for effective injury prevention programs. The aim of this study was to compare an inertial sensor (Xsens) with high-speed cameras during landing. Ten participants performed double and single-leg drop vertical jumps while data from both systems were collected. Joint angle and excursion from Xsens was compared with the high-speed video. Bland and Altman plots and root mean of the squared difference quantified validity. Larger values of knee valgus excursion was reported with Xsens by 0.4-0.7cm. Additionally, Xsens overreported most joint flexion. Although an inertial sensor system may provide valuable information of landing kinematics in an applied environment, the resultant data must be carefully examined prior to drawing conclusions regarding the ACL injury risk of the athlete.
