Abstract Summary
A musculoskeletal simulation study is necessary to identify the cause-effect relationship between hip abductor weakness and ACL loading during athletic events such as landing and jumping. The purpose of this study was to identify the effect of weakness of hip abductors on lower extremity kinematics and ACL loading during single-leg landings. Ten healthy participants performed single-leg landings from a height of 45cm. 3D motion capture and ground reaction force data were used to perform muscle-driven musculoskeletal simulations. No differences between conditions were found in lower extremity kinematics and ACL loading. Future studies will focus on identifying how the extent of weakness of hip abductors alter ACL loading during single-leg landings.
