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.
