Reliability of Nonlinear Kinematic Analysis in Patients with Functional Ankle Instability During Dual-Task Walking

By

SUMMARY Objective. This study aimed to determine the intrasession reliability of nonlinear gait kinematic analysis under single and dual-task conditions in individuals with and without Functional ankle instability (FAI). Methods. Individuals with FAI and healthy subjects completed a walking task on a treadmill, with or without performing an auditory Stroop task. The gait kinematic parameters, including the LyE of … Continued

ACL biomechanical risk factors on single-leg drop-jump: a cohort study comparing football players with and without history of lower limb injury

By

Background. The maximum knee valgus angle (KVA) and minimum knee flexion angle (KFA) have been identified as risk factors for non-contact anterior cruciate ligament (ACL) injury. The present study investigated whether a recent history of lower limb injury in professional male football players can affect KVA and KFA during a single-leg vertical drop-jump (SLVDJ). Methods. … Continued

Anterior cruciate ligament deficiency: rotational instability in the transverse plane. A preliminary laboratory in vivo study

By

Background. Rotational instability is a major feature of anterior cruciate ligament (ACL) deficiency. Few biomechanical studies have focused on the transverse plane when assessing the function of the ACL. Objective. To analyse the biomechanics of ACL deficient knees in the transverse plane under torsional conditions to detect rotational instability. Methods. Seven subjects (eight ACL deficiency) … Continued
