丹麦的研究人员发现，人们越多使用鼠标，他们的手、手腕、脖子和肩越容易有疼痛、发麻及其他问题。学者们认为，引起这种不适的原因不在鼠标而在于使用鼠标时不断重复的动作造成的。目前来讲，最好的解决办法是时常改变鼠标及键盘的使用模式。

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.
