The aim of this study was to investigate whether different work methods with computer mouse had an effect on musculoskeletal load and to study whether there were any gender differences in performance and/or musculoskeletal load. Thirty experienced computer mouse users (15 men and 15 women) performed a text-editing task using two different work methods to operate the mouse. Women worked with higher muscular activity in the forearm, applied higher relative forces to the sides and button of the mouse and worked with more extreme postures in the wrist than men. Differences were also found between the two different work methods used to operate the mouse.
