Developments in Measuring Fatigue Impairment

Research into factors associated with the development and alleviation of fatigue presupposes a means of measuring performance impairment. The National Research Council of Canada has been developing a test of psychomotor performance, known as a stressalyser, which gives scores that are variant with fatigue as indicated by prolonged sleep loss. The test is short but interesting, and the apparatus is compact and portable, and the method offers possibilities of application to problems like the design of working regimes for long distance truck drivers.
