Ragan Context: The healthcare needs of special populations have been met with the application of telemedicine. Running related injuries (RRIs) are frequent among the running population in which clinician conducted gait assessments to identify gait abnormalities are not easily accessible. To increase accessibility of clinician conducted gait assessments, a system was developed with a telemedicine approach. Objective: To determine clinical importance, viewing parameters, and the reliability of clinicians to identify gait abnormalities to develop the Dynamic Injury Screening Tool for the Lower Extremity (DISTLE). The use of DISTLE was then validated. Participants: The participants were currently licensed and practicing athletic trainers. Other participants included physically active volunteers who served as walkers and standardized patients for the third and fourth phases, respectively. Conclusions: The cumulative results display a need for standardization of observation gait assessments and video parameters prior to the application of a telemedicine approach to address the running population’s needs. 4 Dedication Challenges are what make life interesting; Overcoming them is what makes life meaningful. -Ralph Waldo Emerson 5 Acknowledgments I would like to thank my thesis advisor Dr. Brian Ragan for his hard work and dedication to my progress throughout the entire process. The second, third, and fourth phases would not have been possible without the patience, cooperation, and assistance of my fellow graduate classmates. I greatly appreciate the generous funding from the College of Health Sciences and Professions Student Research Grant that promoted the successful completion of my third and fourth phases. The use and disbursement of funds would not have been possible without the patience and guidance of Jane Boney. Special thanks to Mr. Tedd Girouard and all of the athletic trainers associated with the University of Nevada, Las Vegas (UNLV) Athletic Training Education Program for serving as a second data collection site on multiple occasions. Additionally I would like to extend my deepest gratitude to my thesis committee: Dr. Andrew Krause, Dr. Jason White, and Ms. Christina Orozco. 6 Table of Contents Page Abstract
