There are up to an estimated 3.8 million sport-related concussions per year in the United States. Currently concussion consensus statements support a multi-faceted assessment approach for the management of concussions, including vestibular assessments. Within the deaf and hard-of-hearing (D/HoH) population, there may be underlying vestibular dysfunction due to the proximity of the vestibular apparatus to the cochlea, including shared neurovascular supply. Specifically, vestibular assessment outcomes of athletes who are D/HoH may not accurately reflect that of available normative data. If these possible discrepancies are not accurately identified, it may negatively influence the diagnosis, injury management, and return-to-play decisions of athletes who are D/HoH. Therefore, the purpose of this research was to assess concussion rates and vestibular function in athletes who are D/HoH. Aim 1 explored concussion rates in collegiate athletes who are D/HoH. The results of this aim suggest that athletes who are hearing had an increased concussion rate compared to athletes who are D/HoH when looking at all sports combined, football alone, and male athletes alone. No other significant differences regarding concussion rates were identified between groups. Athletes who are D/HoH in sex comparable sports may not have a higher rate of concussion compared to athletes who are hearing. Aim 2 investigated the effect of hearing status on static and dynamic postural control performance of athletes who are D/HoH and athletes who are hearing. The results of this aim indicate that there are static postural control performance differences between athletes who are D/HoH and athletes who are hearing. Athletes who are D/HoH had greater postural sway during conditions 1, 3, and 4 of the modified Clinical Test of Sensory Interaction and Balance (mCTSIB) for total, anterior-posterior (AP), and medial-lateral (ML) center-of-pressure (CoP) excursion, 95% ellipse sway, AP and ML range, and ML CoP root-mean-sqaure (RMS). No statistically significant differences in dynamic postural control performance were found between athletes who are D/HoH and athletes who are hearing. Baseline assessments for static postural control performance may be warranted for athletes who are D/HoH rather than comparing to existing normative data. Aim 3 investigated the effect of hearing status on dynamic visual acuity (DVA) of athletes who are D/HoH and athletes who are hearing. The results suggest that hearing status did not have a significant effect on DVA performance. Additionally, there was no statistically significant DVA performance differences between athletes who are deaf and athletes who are hard-of-hearing. For this assessment, baseline assessments of DVA of athletes who are D/HoH may not be necessary for preseason assessment. Findings from this study suggest that athletes who are D/HoH experience concussions at a similar rate in sex comparable sports to athletes who are hearing. Due to similar concussion rates and possible underlying vestibular dysfunction, special considerations of vestibular assessment outcomes are crucial for appropriate concussion management, and return-to-sport decisions
