The effects of Ergorest arm supports on wrist angles and musculoskeletal strain in the neck-shoulder-arm region and electrical activity in the shoulder and arm muscles were studied during typing or the use of the mouse in work with a visual display unit (VDU). Twenty-one women were randomized into 3 groups (1 arm support, 2 arm supports, and control). Measurements were carried out before and after the 6-week intervention. The wrist extension of the mouse hand, the muscle activity of the trapezius muscle, and the subjective discomfort ratings indicated that 2 arm supports were better than 1 in work with a mouse. The Ergorest arm support alleviates muscle and joint strain in VDU work when used for both arms.
在使用视觉显示单元（VDU）进行打字或使用鼠标工作期间，研究了Ergorest手臂支撑对颈部 - 肩部 - 手臂区域手腕角度、肌肉骨骼应变以及肩部和手臂肌肉电活动的影响。21名女性被随机分为3组（1个手臂支撑组、2个手臂支撑组和对照组）。在为期6周的干预前后进行了测量。使用鼠标工作时，鼠标手的手腕伸展、斜方肌的肌肉活动以及主观不适评分表明，2个手臂支撑比1个手臂支撑效果更好。当双臂都使用时，Ergorest手臂支撑可减轻VDU工作中的肌肉和关节劳损。
