Forty- Versus 20-Minute Trials of the Maintenance of Wakefulness Test Regimen for Licensing of Drivers

摘要

Study Objectives:Objective assessment of the ability to maintain wakefulness, although very important, is still equivocal. A recent study from our lab has shown that the Maintenance of Wakefulness Test (MWT), when performed with the 20-minute protocol (MWT20), is unreliable in assessing patients who are highly motivated to maintain wakefulness. In this study, we sought to examine whether the 40-minute protocol (MWT40) is a better tool in assessing such individuals.
