Title Effects of Ergorest arm supports on muscle strain and wrist positions during the use of the mouse and keyboard in work with visual display units: A work site intervention
Bibliographic information 2001, Vol.7, No.1, p.103-116. Illus. 23 ref.
Abstract 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). 21 women were divided into three groups (one arm support, two arm supports, and control). Measurements were carried out before and after the six-week intervention. The wrist extension of the mouse hand, the muscle activity of the trapezius muscle, and the subjective discomfort ratings indicated that two arm supports were better than one during work with a mouse. The Ergorest arm support alleviates muscle and joint strain in VDU work when used for both arms.
