Abstract |
Working posture and electromyographic activities of the neck and shoulder muscles were determined in ten video display terminal operators performing a mouse-driven interactive task at screen height settings of 80, 100 and 120cm. Changes in body positions were measured by video image and frame analysis. At greater screen heights, the neck became significantly more erect, and subjects assumed a more backward leaning trunk position. A more upright position of the neck may result in decreased load on the neck extensor muscles, as indicated by the strong correlation between neck flexion and neck extensor muscle activity. |
