丹麥的研究人員發現，人們越多使用鼠標，他們的手、手腕、脖子和肩越容易有疼痛、發麻及其他問題。學者們認為，引起這種不適的原因不在鼠標而在于使用鼠標時不斷重復的動作造成的。目前來講，最好的解決辦法是時常改變鼠標及鍵盤的使用模式。

    The more you click using your computer's mouse, the greater the chance of suffering from pain, swelling, numbness and other problems in the hand, wrist, neck and shoulder, two teams of Danish researchers reported at a meeting here this week.

    "The problem is not only the mouse, but performing repetitive tasks," Jensen from the National Institute of Occupational Health in Copenhagen told Reuters Health.

    Jensen said that a variable pattern of mouse and keyboard use can be considered the best combination from an occupational health perspective. Other measures have uncertain effects.
