LONG-TERM STABILITY OF STANDARD DEVIATION OF LATERAL POSITION IN NEUROCOGNITIVELY NORMAL AND IMPAIRED INDIVIDUALS

A driving metric that is commonly used in studies of the acute effects of medication and illicit drugs is the standards deviation of lateral position (SDLP). SDLP is a measurement of how well subjects maintain their lane position, providing an index for each subject's road tracking error and ability to control the lateral motion of the car. The simulator assessments used in this study were brief, and it is likely that longer assessments would improve sensitivity and reliability. However, the goal of this assessment approach was to develop a brief measure that might be feasible for use in multi-site clinical trials where resources and time are often limited. Yet the present study provides data suggesting that SDLP may serve as a reliable and useful tool in the long term tracking of driving abilities. Future studies should consider incorporating driving measures as an important outcome.
