Athletic Training and Clinical Nutrition Faculty Publications

PURPOSE: The aim of the study was to determine whether corticospinal excitability and inhibition of the tibialis anterior during single-leg standing differs among individuals with chronic ankle instability (CAI), lateral ankle sprain copers, and healthy controls.

METHODS: Twenty-three participants with CAI, 23 lateral ankle sprain copers, and 24 healthy control participants volunteered. Active motor threshold (AMT), normalized motor-evoked potential (MEP), and cortical silent period (CSP) were evaluated by transcranial magnetic stimulation while participants performed a single-leg standing task.

RESULTS: Participants with CAI had significantly longer CSP at 100% of AMT and lower normalized MEP at 120% of AMT compared to …

Prediction Of Acute And Recurrent Ankle Sprains In Athletes, Ryan S. Mccann

Theses and Dissertations--Rehabilitation Sciences

Ankle sprains are not only among the most common sport-related injuries, but also associated with a high rate of recurrence. While prevention is a favorable approach to reducing the incidence of index and recurrent ankle sprains, identifying individuals at greater risk may improve allocation of preventative resources. This dissertation aimed to accomplish the following through three aims: 1) determine the ability of baseline clinical tests to predict acute lateral ankle sprain (LAS) in an understudied athletic population, 2) describe the degree of residual impairments and activity limitations in athletes returning to play from a LAS, and 3) determine the ability …

Methods For Determining Time To Return To Play After Recreational Injury In Field And Court Sport Athletes, Sarah N. Morris

Theses and Dissertations--Epidemiology and Biostatistics

An observational study was used to illustrate the application of time to event analysis methods to return to play; a secondary data analysis of athlete injury data from the High School RIO^TM Injury Surveillance System (ISS) database was conducted. National Athletic Trainers’ Association (NATA)-certified athletic trainers from approximately 100 high schools in the US enroll their school in the system and complete the online “Exposure Report Form” for reportable injuries each week. New lateral ankle sprains and single-ligament knee injuries experienced by high school athletes during regularly scheduled participation in school-sanctioned sports for seven academic years (2005-2006 through 2011-2012) …
