内容提要：Sales of laptop computers passed desktops in the U.S. for the first time ever this fall, according to market-research firm IDC.

人体工学专家多年来一直在提醒笔记本电脑的问题，但是往往是徒劳无功。人们继续丢掉笨重的台式电脑，转向更加轻薄的笔记本电脑。而且无线上网技术还让我们可以在任何地方使用笔记本电脑──床上、地板上──姿势也可以千奇百怪。
People think, How can a mouse or a keyboard hurt you?'' says Thomas Caffrey, founder of Myofactors LLC, which does ergonomic consultations for factories and offices (including The Wall Street Journal). But poor technique can significantly overload the anatomy over time."
Myofactors LLC的创始人托马斯·凯弗雷(Thomas Caffrey)说，人们会想，一个鼠标或键盘怎么会使你受到伤害呢？但是随着时间的推移，糟糕的姿势可能会对人体带来明显的重负。该公司为工厂和办公室提供人体工学咨询服务。
A wrong position can cause pain and stiffness in the neck, shoulders, back and arms, as well as headaches, pains in the temporomandibular joint (TMJ) and carpal tunnel syndrome, in which pressure on wrist nerves causes tingling and numbness in the hands.
错误的姿势不但可以造成颈、肩、背和手臂的疼痛和僵硬，而且还会导致头痛、颞下颌关节疼痛和腕管综合症。腕管综合症患者的腕部神经受到压迫，导致手上产生刺痛或是麻木的感觉。
