▼ Ankle inversion studies have utilized various inversion platforms and EMG analysis. Studies are needed that better describe the kinetics and kinematics of these dynamic inversion moments. A MANOVA was used to analyze the kinetics and kinematics of expected and unexpected single leg drop landing ankle inversion. Twenty centimeter single leg drop landing trials were randomized between a flat surface or 30° inversion wedge. After each trial, subjects reported whether the surface was expected or unexpected. Each subject repeated trials until four expected and four unexpected trials onto the inversion wedge were recorded. Kinetics and kinematics were described by analyzing vertical ground reaction force (VGRF), electromyography (EMG), and 2D motion analysis. Data was collected for maximum ankle inversion, maximum inversion velocity, peak EMG, maximum VGRF, time from contact to: maximum ankle inversion, peak EMG, and maximum VGRF, and time from maximum ankle inversion to peak EMG, time from maximum VGRF to peak EMG were recorded.

▼ Objective: To determine the rate and risk of injury associated with high school athletic participation and assess the licensed athletic trainer’s (LAT) role as the point of first contact for non-athletic orthopedic and nonorthopedic conditions suffered by nonathletes and athletes. Participants: Eight southeastern Ohio high schools with 2,202 athletes, ranging in age from 13 to 19 (15.8±1.2). Methods: Injury information was submitted to the researchers by the LAT. Main Outcome Measures: Frequency, clinical incidence rates, and injury rates. Results: Over 3 seasons 651 orthopedic and 41 nonorthopedic conditions were reported. Twenty-one of the 651 orthopedic injuries were non-athletic related. Football sustained the most injuries. Strains (24.7%) were the most common orthopedic injury. Influenza (14.6%) was the most common nonorthopedic condition. Conclusion: Injury rates were higher than previous literature. Lower extremity was consistent with literature for most frequently injured body area. Nonorthopedic conditions were reported higher than other research. Advisors/Committee Members: Starkey, Chad.

▼ This study examined both athletes’ and athletic trainers’ perceptions on motivation and social support of injured athletes during rehabilitation. Investigating how athletic trainers motivate athletes and give social support to perform his/her rehabilitation provides insight to the impact athletic trainers have in caring for and rehabilitating injuries. Two electronic surveys, the athletic trainer survey and the athlete survey were constructed using Survey Monkey. Data were collected on the perceived motivation of injured athletes in rehabilitation, the injured athletes’ and athletic trainers’ views of motivation, and the athletic trainers’ role in motivating the injured athlete and provide social support in rehabilitation. Data analysis with an ANOVA indicated athletic trainers’ vital role in the motivation and social support of injured athletes during rehabilitation. Athletic trainers were identified as the most important individual in motivating and providing reality confirmation, task appreciation, task challenge, and emotional challenge and support.
