Can a shorter psychomotor vigilance task be used as a reasonable substitute for the ten-minute psychomotor vigilance task?
The 10 min psychomotor vigilance task (PVT) is commonly used in laboratory studies to assess the impact of sleep loss, sustained wakefulness, and/or time of day on neurobehavioral performance. In field settings, though, it may be impractical for participants to perform a test of this length. The aim of this study was to identify a performance measure that is sensitive to the effects of fatigue ...
متن کاملPsychomotor vigilance testing of professional drivers in the occupational health clinic: a potential objective screen for daytime sleepiness.
OBJECTIVE Psychomotor vigilance testing (PVT) rapidly assesses attention, reaction time (RT), and abnormal vigilance. Thus, PVT may be an adjunct to screening drivers for high-risk obstructive sleep apnea (OSA)/excess daytime sleepiness (EDS). METHODS Commercial drivers and emergency responders undergoing occupational examinations took a 10-minute PVT and were instructed to achieve their fast...
متن کاملObstructive sleep apnea and psychomotor vigilance task performance
BACKGROUND Obstructive sleep apnea (OSA) is a highly prevalent disorder with considerable morbidity and mortality. Vigilance and attentiveness are often impaired in OSA patients. In occupational medicine settings, subjective reports of sleepiness are notoriously inaccurate, making the identification of objective measures of vigilance potentially important for risk assessments of fitness for dut...
متن کاملThe neural basis of the psychomotor vigilance task.
STUDY OBJECTIVE To identify brain regions underlying the fastest and slowest reaction times on the Psychomotor Vigilance task (PVT) under well-rested conditions, as well as brain regions related to particularly poor performance after sleep deprivation. DESIGN Subjects took the PVT twice while undergoing functional magnetic resonance imaging: once 12 hours after waking from a normal night of s...
متن کاملExcessive daytime sleepiness.
Excessive daytime sleepiness is one of the most common sleep-related patient symptoms, and it affects an estimated 20 percent of the population. Persons with excessive daytime sleepiness are at risk of motor vehicle and work-related incidents, and have poorer health than comparable adults. The most common causes of excessive daytime sleepiness are sleep deprivation, obstructive sleep apnea, and...
