Abstract or Description
An estimated 1.6 - 3.8 million concussions occur annually in the United States [1]. Approximately 30% of sport-related concussions (SRC) experience postural instability immediately post-injury, while 75.6% report dizziness as a debilitating symptom [2,3]. Postural instability post-SRC has been well documented using numerous methods [3]. Kinetic quiet stance measures observed that concussed athletes have elevated postural sway magnitude and greater sway velocity within 24-48 hours post-SRC [4]. In addition, postural instability has been noted within 48-96 hours post-SRC using complex dual-task and dynamic assessments [5]. However, very little is known about the diagnostic validity of these postural assessments post-SRC.
The purpose of this study is to investigate the diagnostic validity of two postural stability methods, quiet upright stance and a sport-like postural task, within 24-48 hours post-SRC.
