Shift Work

Motionlogger Actigraphs can easily measure the sleep/wake cycles of shift workers in order to assess their adaptability to work cycles. Numerous industrial settings do not permit regularly schedules employee work hours -- such irregularity, for example, being commonplace in U.S. rail and other transportation industries. Thus the relationship between the work hours and sleep habits of locomotive engineers and drivers is of importance as it relates to both alertness and avoidance of accidents. The same is true with regard to the long work hours, partial sleep deprivation, and high workload of medical residents, in that these factors can result in serious consequences of wrong decision-making in crucial medical situations.

Our Motionlogger Actigraphs can be used to assess sleep under varying work schedules, and environmental sensors can monitor the light, sound, and temperature levels in a shift worker's daytime sleeping environment. In addition, out PVT-192 Psychomotor Vigilance Task Monitor, which is a hand-held, self-contained system used for repetitive reaction time measurement, provides a valuable complement to our Motionlogger Actigraph for testing awareness and the effects of sleep deprivation.
