摘要: The aim of this study was to compare the postural load during VDU work in following postures: (1) Supporting and not supporting forearms on table top, (2) Sitting standing positions, (3) Sightline centre screen at an angle 15 degrees 30 below horizontal. muscle from upper part musculus trapezius lumbar erector spinae (L3 level) measured by electromyography (EMG). Postural angles head, arm back were inclinometers. m. when using keyboard significantly less sitting with supported compared without forearm support. Further, time number periods 1% MVC greater support versus no right lumbalis also longer a position In addition, mouse reduced static sitting. results document clearly importance giving operator possibility top.
