Crutch

A crutch is a mobility aid that transfers weight from the legs to the upper body. It is often used by people who cannot use their legs to support their weight, for reasons ranging from short-term injuries to lifelong disabilities.

In 1917, Emile Schlick patented the first commercially produced crutch; the design consisted of a walking stick with an upper arm support. Later, A.R. Lofstrand, Jr. developed the first crutches with a height-adjustable feature making the crutches customizable. Through time, the design of crutches haven't changed much such that the classic design still is most commonly used.
