Barrack, Skinner, and Buckley's (2015) study aimed to determine the effect of anterior cruciate ligament (ACL) deficiency on proprioception in the knee joint. The background of the study is that ACL injury is a common sports injury that can lead to instability and proprioceptive deficits in the knee joint. The study used a proprioceptive testing device to measure joint position sense and found that ACL deficiency led to significant deficits in proprioception. The study concluded that proprioceptive training should be incorporated into the rehabilitation of ACL-deficient knees to improve functional outcomes.

Crowell, Milner, Hamill, and Davis's (2010) study aimed to reduce impact loading during running using real-time visual feedback. The background of the study is that high impact loading during running is a contributing factor to running-related injuries. The study used a motion analysis system with real-time feedback to cue runners to reduce their impact loading. The study found that runners reduced their impact loading by 13% after receiving real-time feedback. The study concluded that real-time visual feedback can be an effective tool to reduce impact loading during running and prevent running-related injuries.

Delahunt, Coughlan, Caulfield, Nightingale, and Lin's (2010) study aimed to establish inclusion criteria for investigating insufficiencies in chronic ankle instability. The background of the study is that chronic ankle instability is a common condition that can lead to recurrent ankle sprains and decreased ankle function. The study reviewed the literature to establish criteria for inclusion in research studies investigating chronic ankle instability. The study concluded that inclusion criteria should include a history of recurrent ankle sprains, subjective feelings of ankle instability, and objective measurements of ankle instability.

Konradsen, Ravn, and Plesner's (1999) study aimed to investigate the role of the dynamic defense mechanism in preventing ankle inversion injuries. The background of the study is that ankle inversion injuries are a common sports injury that can lead to chronic ankle instability. The study used a motion analysis system to measure ankle joint kinematics during sudden inversion movements. The study found that the dynamic defense mechanism, which includes muscle contractions and joint position sense, plays a critical role in preventing ankle inversion injuries. The study concluded that interventions aimed at improving the dynamic defense mechanism may prevent ankle inversion injuries.

Overall, these studies contribute to our understanding of factors that contribute to sports injuries and how to prevent them. They use a range of methods, including motion analysis systems, proprioceptive testing devices, and real-time feedback, to investigate different aspects of sports injuries. By comparing and contrasting their findings, we can gain a more comprehensive understanding of the mechanisms underlying sports injuries and how to prevent them.
