Two experiments were conducted to examine how time-ontask (i.e., practice and fatigue) influences eye movements during visual search. In Experiment 1, we examined how practice influences eye movements during an extended visual search task. Results replicate the findings that over the course of a visual search task, performance improves and fixation duration increases. Yet changes in fixation du...

BACKGROUND AND AIMS There are no available effective therapies for fatigue associated with chronic hepatitis C (CHC). The serotonin antagonist ondansetron has been shown to be effective in the chronic fatigue syndrome. In this randomised, placebo controlled, double blind trial, we investigated the effect of orally administered ondansetron on fatigue in CHC. METHODS Thirty six patients with CH...

The study described in this article was designed to evaluate visual fatigue induced during video display terminal (VDT) tasks. Newly developed equipment was used that can simultaneously measure pupillary change, focal accommodation, and eye movement. The changes in these 3 physiological measures, taken during a VDT task, were used to propose an index for evaluating visual fatigue. Through multi...

[Purpose] The purpose of this study was to determine the effects of visual fatigue caused by smartphone use on balance function. [Subjects and Methods] The participants consisted of 22 healthy male and female adults. Their postural stability, limit of stability, and limit of stability running time were evaluated using a computerized posturography apparatus before and after inducing visual fatig...

Approximately 30% of the general population suffers from insomnia. Given that insomnia causes many problems, amelioration of the symptoms is crucial. Recently, we found that a non-essential amino acid, glycine subjectively and objectively improves sleep quality in humans who have difficulty sleeping. We evaluated the effects of glycine on daytime sleepiness, fatigue, and performances in sleep-r...

lthough fatigue is the most common complaints reported by patients in primary care [1], last decades of research have been hampered by the lack of an objective measurement of the subjective experience of fatigue. The Fatigue Impact Scale (FIS) questionnaire was developed in 1994 by Fisk and colleagues to quantify the specific impact of fatigue on quality of life [2]. In Hepatogastroenterology, ...
