Anterior positioning of tibia during motion after anterior cruciate ligament injury

Article Abstract:

This article compares tibial positioning and muscle activity during locomotion in subjects with an injury in the anterior cruciate ligament and noninjured controls. Findings indicate that the tibias of injured subjects moved to an anterior position more quickly and remained there longer during the walking cycle when compared to healthy subjects.

Effects of position and speed on joint torques and knee shear after ACL injury

Article Abstract:

This article examines the effect of movement speed and joint position on extensor torque in the knee and hip and the magnitude of knee shear. Findings indicate that speed of motion and the position of joints significantly influence anterior tibial shear and torque measurements in the hip and knee.

EMG power spectra of intercollegiate athletes and anterior cruciate ligament injury risk in females

Article Abstract:

Electromyographic (EMG) spectra of the quadriceps and hamstring muscles reveals differences between female and male intercollegiate athletes. Results indicate that increased coactivation of the quadriceps in females may enhance anterior tibial loads during exercie, causing the anterior cruciate ligament at higher risk for injury.
