Anterior cruciate ligament (ACL) injuries are common in sports. Knee injuries are the most common, and have the greatest potential to cause both short term and long term disability. Dynamic stability of the knee during such activities is determined by the balance of muscle strength, lower extremity muscle fatigue, ligament function, joint structures contact, and ground reaction forces applied to the leg. The purpose of this research was to determine the effect of the controlled landing tests in dynamic stability. Optoelectronic system BTS ELITE, offering integration of kinematics data with the external signals of force platforms and EMG devices, was used for experiments. The developed test protocol could be applicable as an indicator of readiness of athletes to sustain training workload as well as a predictor of injury occurrence in healthy people. |
