Sources of Data Data was collected from a non-validated survey, which was created by the researcher for the purposes of this study. The participants were selected randomly from the National Athletic Training Associations online member database of Certified Athletic Trainers employed at the collegiate setting. Once selected, the National Athletic Training Research Survey Service emailed the participants with a link to the Survey. The survey was made available through Survey Monkey, an online survey service. v Conclusions Reached The data collected revealed that out of the 161 total reported Syndesmosis Ankle Sprains, 47.2% of the injuries occurred while ankle support was being utilized. Where as, only 14.9% of the athletes were wearing a form of knee support at the time of injury, and 12.4% of injuries occurred with both ankle and knee support being utilized. Additionally, there was also an increased number of Syndesmosis Ankle Sprains reported in football when compared to other sports. _______________________, Committee Chair Michael Wright, Ph.D. _______________________ Date vi ACKNOWLEDGEMENTS I would like to thank my committee, Michael Wright and Heather Swanson for their continued support and assistance with this project. I cannot thank them enough for their guidance throughout the Master’s program, especially during the thesis process. vii TABLE OF CONTENTS Page Acknowledgements .................................................................................................... vii List of Tables .............................................................................................................. xi List of Figures ............................................................................................................ xii Chapter 1.
