Abstract

Purpose: This study compared the characteristics of the brake response time during the driving task between elderly and younger drivers. Methods: The participants consisted of an elderly group (n=12) and a younger group (n=12). The brake response time (BRT), which consisted of the reaction time (RT) and movement time (MT), was assessed in an actual driving car. The BRT was measured at the initiation and termination of the brake response for the driving task Results: The elderly group showed a significantly longer delay in the initiation and termination of the brake response than the younger group. The BRT correlated significantly with both the RT and MT. However, the RT showed a more significant correlation. Conclusion: A delay in the initiation and termination of the brake response may have clinical implications. A further study will be needed to determine the different factors contributing to the driving performance of elderly drivers.
