abstract="OBJECTIVES: Recent retrospective studies report differences in auditory neurophysiology between concussed athletes and uninjured controls using the  frequency-following response (FFR). Adopting a prospective design in college  football players, we compared FFRs before and after a concussion and evaluated  test-retest reliability in non-concussed teammates. <br><br>DESIGN: Testing took place in a  locker room. We analysed the FFR to the fundamental frequency (F0) (FFR-F0) of a  speech stimulus, previously identified as a potential concussion biomarker. Baseline  FFRs were obtained during the football pre-season. In athletes diagnosed with  concussions during the season, FFRs were measured days after injury and compared to  pre-season baseline. In uninjured controls, comparisons were made between pre- and  post-season. STUDY SAMPLE: Participants were Tulane University football athletes  (n = 65). <br><br>RESULTS: In concussed athletes, there was a significant group-level  decrease in FFR-F0 from baseline (26% decrease on average). By contrast, the control  group's change from baseline was not statistically significant, and comparisons of  pre- and post-season had good repeatability (intraclass correlation coefficient =  0.75). <br><br>CONCLUSIONS: Results converge with previous work to evince suppressed neural  function to the FFR-F0 following concussion. This preliminary study paves the way  for larger-scale clinical evaluation of the specificity and reliability of the FFR  as a concussion diagnostic. Highlights This prospective study reveals suppressed  neural responses to sound in concussed athletes compared to baseline. Neural  responses to sound show good repeatability in uninjured athletes tested in a  locker-room setting. <br><br>RESULTS support the feasibility of recording  frequency-following responses in non-laboratory conditions.<p /> <p>Language: en</p>",
