Giving VDU operators the possibility to support of the forearms on the table top in front of the them and operating the mouse with a more neutral position of the forearm, reduced significantly the load on the extensor digitorum conununis, extensor carpi ulnaris and musculus trapezius with a corresponding reduction of pain in the upper part of the body.The static load seem to be predictor for the development of musculoskeletal illness in the upper part of the body.
