Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Clinical Scenario: The core is a functional unit connecting the upper and lower extremities consisting of abdominal, back, and hip musculature. A highly functional core is essential within the kinetic chain and aids in injury prevention and rehabilitation. Traditional means of core stability training are performed on a stable surface. An emerging mode of core training is suspension training (ST), which utilizes a movement paired with instability to challenge the core stabilizers and increase motor unit recruitment.The purpose of suspension training is to increase muscle activation in core stabilizer’s, while mimicking functional movements.It was the purpose of this research to …

Using External Visual Feedback Techniques To Improve Chronic Ankle Instability: A Critically Appraised Topic, Paxtyn Watkins, Bradlee Wells, Aric J. Warren

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Introduction: Lateral ankle sprains (LAS) are among the most common musculoskeletal injury in physically active populations posing a substantial health burden. Individuals who sustain ankle sprains often have a diminished quality of life with prolonged symptoms, decreased levels of physical activity, and the propensity to develop chronic ankle instability (CAI). It is estimated that up to 40% of people who sustain an initial lateral ankle sprain will develop CAI. Many therapeutic interventions exist to help alleviate symptoms and the feeling of “giving out.” This critically appraised topic will examine multiple interventions that involve using external visual feedback methods to improve …

The Impact Of Athletic Retirement On Anxiety In Elite Athletes, A Critically Appraised Topic, Jordan Gorham, Emily Madrak

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Though there is growing interest in athletic mental health, this interest appears to diminish significantly once an athlete enters athletic retirement. The abrupt transition can precipitate mental health struggles, exacerbated by the lack of adequate preparation for lifestyle after retirement and the attachment of athletic identity to their sport. Consequently, these circumstances may increase symptoms associated with poor mental health, with a specific focus on anxiety. As the athlete retires and moves into different stages of life, research notes that athletes with stronger athletic identities have poorer mental health than those who had weaker athletic identity^. While the scrutiny …

Modeling Surgeon Belief Updating Under Bias: A Bayesian Simulation In Shoulder Arthroplasty, Mariano Menendez, Michael Moverman, Surena Namdari, Frederick Matsen, David Ring

Rothman Institute Papers

BACKGROUND: Shoulder surgeons often offer markedly different treatment recommendations for a given patient and pathophysiology within the context of a common body of evidence. Prior beliefs and cognitive bias may contribute to this variability. Using Bayesian decision theory informed by principles of behavioral science, we modeled how surgeons with different initial beliefs and degrees of bias update their treatment preferences in response to new evidence comparing anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) when making surgery recommendations for advanced primary glenohumeral osteoarthritis.

METHODS: We developed a Bayesian simulation involving 3 hypothetical surgeons with distinct initial beliefs: …
