Phone neck refers to neck pain caused by holding a telephone between one's shoulder and ear for extended periods. It is one of the modern white-collar ailments¹.

电话脖（phone neck）指把电话夹在肩膀和耳朵之间很长时间引起的颈部疼痛，是现代白领病的一种。

A variation on the theme is cellular² phone neck, implausibly caused by a driver jamming a phone between his ear and shoulder so that he can keep both hands on the wheel.

这个词还有个衍生说法是“手机脖”（cellular phone neck），是驾驶员为了保证双手都在方向盘上，所以将手机夹在肩膀和耳朵之间引起的不适反应。

由此，我们可以类推出，“鼠标手”就是mouse hand，“电脑背”则是computer spine³。
