摘要

This study examined the working situations of 48 laptop computer (LC) users. The most notable disadvantage reported was that of musculoskeletal discomfort, mainly in the neck. Ten subjects who used their LC both on a desk and on their laps were observed, photographed, and their postural angles measured. Sign tests demonstrated significantly greater neck, shoulder, and viewing angles when work was performed with the LC set up on the lap. Viewing distances were also significantly shorter when LCs were used on laps. Discomfort-time plots were compared for 6 subjects who completed two ninety-minute work periods, with the LC used on a desk and with the LC used on the lap. The most frequently reported areas of discomfort were the neck and thoracic spine. Regression analysis indicated that LC work on the lap is indeed less comfortable than LC work on a desk.
