The potential utility of driving simulators in the cognitive rehabilitation of combat-returnees with traumatic brain injury.

A large number of Operation Enduring Freedom/Operation Iraqi Freedom returnees are seeking DOD and VA rehabilitative care for war-related traumatic brain injury (TBI). This article reviews evidence on the utility of driving simulators as tools for assessment and training in TBI rehabilitation. Traditionally, cognitive rehabilitation has been shown to improve specific cognitive skills. However, there are few studies and only weak evidence to show that these gains transfer to everyday activities. Theoretically, modern driving simulators may be useful in cognitive rehabilitation because they can systematically present realistic and interesting tasks that approximate driving activities, while automatically monitoring performance. The use of simulation technology for patients with TBI provides cognitive stimulation in an ecologically compatible setting, without the risks associated with a corresponding real-world experience. The utility, limitations, and future directions for the use of driving simulator in the rehabilitation of patients with war-related TBI are discussed.
