Abstract. [Purpose] This study evaluated the efficacy of a newly designed chair, equipped with a Posture Sensing Composite Display Device (PSCD), for correcting poor trunk posture while performing computer work.[Subjects] We recruited 10 male workers who regularly used a computer for at least 8h per day.[Methods] Subjects performed computer work while sitting on the newly designed chair with or without the PSCD. Lumbopelvic kinematic data were recorded for 60 s following 10, 20, and 30 min of computer work using a three-dimensional motion analysis system.[Results] The newly designed chair equipped with the PSCD significantly reduced lumbar flexion, lateral bending, and rotation during computer work.[Conclusion] The PSCD may prevent work-related musculoskeletal disorders by enabling a worker to maintain an upright posture during computer work.

“…They can lead to a variety of problems, such as physical discomfort (dry eyes or rising heart rates) [2], psychological discomfort (anxiety or frustration), and financial losses cause by increased error rates [3][4][5]. Methods such as analyzing EEG, eye signals, or ECG, could be used to evaluate user fatigue, but these methods are not effective for daily testing [6,7].…”

Abstract. In this paper, participants operated visual display terminals (VDT); the authors analyzed their pulse wave signals to develop objective indices for diagnosing and assessing VDT-induced. The experiment used 30 healthy undergraduates test subjects; each subject operated static PC for 4 hours. The pulse waves of local blood volumes in the test subjects' finger-tips were measured every 30 minutes for 2 minutes. After the experiment, the pulse wave parameters were analyzed. All test subjects exhibited signs of visual fatigue according to the fatigue scale results. There were significant differences of heart rate (HR), which clearly declined before and after the experiment (P<0.01). The indexes RMSSD, SDNN, P3, P4, P5, P6, and TP had significant differences (P<0.01) and all rose. The positions of the main and dicrotic waves advanced (P<0.01). The experiment parameters prompted significant changes; pulse wave forms changed during VDT work. Based on these results, pulse wave analysis holds promise as an effective, noninvasive technique for measuring VDT fatigue.

“…* Partly presented at the 5 th Croatian Congress on Occupational Health with International Participation "Healt, Work, and Community", Hvar, Croatia, 28 September to 2 October 2011 Research shows that workers at video display terminals (VDT) mostly suffer from neck problems and upper and lower back pain but ergonomic interventions can reduce these difficulties (1,2). Improper display height leads to faster and more pronounced trapezius muscle strain (3).…”

Frequency of Musculoskeletal and Eye Symptoms among Computer Users at WorkComputer users most often complain of the eye and locomotor system disorders. The goal of this paper was to find out the frequency and relation between musculoskeletal and eye symptoms among computer workers.The data on musculoskeletal and eye symptoms were provided by two questionnaires. Forty-nine workers were included in the study. Their mean age was 41 years and average length of service 16 years. The average amount of time they spent in front of computers was 6.73 hours per day. Women spent more time working at a computer per day than men (P=0.025). The most frequent complaint in the past year referred to the upper back pain (30.6 % of the workers). Every fourth worker, i.e. 24.5 % of them experienced neck pain in the past year; women more often than men (P=0.024). A health problem which reduced the range of motion and prompted the workers to ask for sick leave was lower back pain. The relation between eye symptoms and the upper back pain experienced in the past year (P=0.004), and in the last week (P=0.031) was statistically significant.Proper exercises for stretching musculoskeletal system, ergonomic computer equipment, and artificial tears could decrease muscular and eye problems, which in turn could enhance productivity and reduce sick leaves.
