In recent years, on international conferences concussion in sport have been discussed, and some of which begun to examine in para-sports.
However, there are few reports of concussion in deaf athlete. Therefore, concussion guidelines for deaf athletes have not been established. In this case report, we report on the use of concussion baseline assessments for deaf athletes for the purpose of sport safety management.
The subjects were 7 deaf athletes (4males and 3 females). Vestibular Ocular Motor Screening (VOMS) was used as baseline concussion Assessment.
On the measurement, the near point of convergence was high. Results of this report showed that the baseline assessment of concussion in deaf individuals may have different results from those in hearing individuals.
In addition, deaf individuals may have difficulty interpreting the movement speed instructions during administration of the VOMS.
This presentation was oral-presentation at the 3^rd Annual Meeting of Japanese of Para-Sports Trainers.
