Effects of an Injury Prevention Program on Anterior Cruciate Ligament Injury Risk Factors in Adolescent Females at Different Stages of Maturation.

The ideal timing to implement anterior cruciate ligament injury prevention programs with respect to maturation is unclear. The purpose of this study was to investigate the effects of an injury prevention program on knee mechanics in early-, late-, and post-pubertal females. In the study, 178 adolescent female basketball players were assigned to six groups: early-pubertal training, early-pubertal control, late-pubertal training, and late-pubertal control, post-pubertal training, and post-pubertal control.

In vivo talocrural and subtalar kinematics during the stance phase of walking in individuals with repetitive ankle sprains.

Ankle sprains may lead to chronic ankle instability and can progress to ankle osteoarthritis due to the abnormal kinematics after an ankle sprain. However, the characteristics of talocrural and subtalar joint kinematics in individuals with repetitive ankle sprains during locomotion is unclear. The purpose of this study was to quantify the differences of talocrural and subtalar joint kinematics between individuals with and without history of ankle sprains during the walking stance phase.

Comparison of the Position-Matching and Position-Reproducing Tasks to Detect Deficits in Knee Position Sense After Reconstruction of the Anterior Cruciate Ligament.

Context: Deficits in knee position sense following reconstruction of the anterior cruciate ligament (ACL) can delay an athlete's return to sport participation and increase the risk of reinjury. Deficits in position sense postreconstruction have been evaluated using either a position-reproducing or position-matching task.

Objective: The aim of our study was to combine both to determine which assessment would be more effective to identify deficits in knee position sense.

Sex differences in three-dimensional talocrural and subtalar joint kinematics during stance phase in healthy young adults.

The ankle joint, including the talocrural and subtalar joints, plays an important role in human locomotion. Sex differences in walking patterns among young and old adults have been studied; however, little information exists on sex-based variations in talocrural and subtalar joint kinematics during walking. Thus, the purpose of this study was to investigate sex-based differences in the talocrural and subtalar joint kinematics during walking.
