PURPOSE: To study how objectively recorded @entity19 and keyboard activity affects @entity158 among computer workers. METHODS: Computer activities were recorded among 2,146 computer workers. For 52 weeks @entity19 and keyboard time, sustained activity, speed and micropauses were recorded with a software program installed on the @entity1 ' computers. @entity1 reported weekly @entity158 scores via the software program for elbow, forearm and wrist/hand as well as in a questionnaire at baseline and 1-year follow up. Associations between @entity158 development and computer work were examined for three @entity158 outcomes: acute, prolonged and @entity1118 . RESULTS: @entity19 time, even at low levels, was associated with acute @entity158 in a similar way for all the examined regions. There were no exposure-response threshold patterns. Keyboard time had no effect. @entity19 and keyboard sustained activity, speed and micropauses were not risk factors for acute @entity158 , nor did they modify the effects of @entity19 or keyboard time. Computer usage parameters were not associated with prolonged or @entity1118 . A major limitation of the study was low keyboard times. CONCLUSION: Computer work was not related to the development of prolonged or @entity1118 . @entity19 time was associated with @entity12761 , but the impact was quite small.
