摘要: In spite of the rapid increase computer use in our everyday life, not much effort is undertaken to take measures prevent Musculoskeletal Disorders(MSDs). this paper, we suggest a movable armrest which would lower exposure MSDs, especially on vicinity arm. The aim study determine whether there are differences wrist angle variations, forearm muscular loads, comfort and normal performance between invented conventional when using mouse. Eight experienced VDU workers performed standardized simple task set consists 15 detailed tasks with each armrest. variations right arm were registered by electrogoniometer muscle activities shoulder, deltoid two extensors also electromyograph. subjects rated perceived while performing Working armrest, compared general, gave significantly decreased at most both biaxial movements. Moreover, as distance targets increased, difference different situations trend be increasing. At same time, work more they showed performances 8 mainly caused macro moving time.
