==History== Crutches were used in ancient Egypt. 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. Over time, the design of crutches has not changed much, and the classic design continues to be the most commonly used.
