走路看手機，吃飯看手機，坐車還看手機，低頭族已經成為普遍現象，而這樣無休止的低頭看手機姿勢卻導致上背部脊柱彎曲，甚至可能造成永久性損傷。

An epidemic is affecting students worldwide; the painful result of our generation being the first to grow up with an endless availability of smart phones, laptops, iPads and gaming consoles. It is the “iHunch”, the forward curve of the upper back caused by constantly looking down at a smartphone or similar device. The iHunch can result in permanent curvature of the spine and is the underlying problem of most neck and back issues and up to 50 percent of headaches.
全世界的學生們都正在受一種通行病癥的困擾，而這個病癥是我們這一代伴隨著智能手機、手提電腦、平板電腦以及游戲機長大的人面臨的痛苦結局。這個病癥就是“i弓背”，因長期連續(xù)低頭查看智能手機等電子設備而導致的上背部彎曲。這種弓背癥狀可能會導致脊柱永久性彎曲，同時也是大部分頸部和背部問題以及五成頭疼問題的誘因。

之所以用iHunch這個說法，大概是因為蘋果公司的iPhone和iPad系列已經成為智能手機和平板系列產品的代表了吧。

The screens of the electronic devices we are consistently using cannot be separated from the keyboard, so students are forced to bend over at the upper back in order to use them, unlike desktop computers which can be set up to be reasonably ergonomically safe.
我們經常使用的電子設備屏幕和鍵盤是一體的，因此，學生們使用時難免弓著背。智能電子設備不像臺式電腦那樣能夠按照人體工程學的安全要求設置屏幕和鍵盤的高度。
