Lofstrand Crutches
Crutches, in general, are medical devices that assist people ambulate from one place to another when they are unable to walk due to an illness or injury. They act as an assistive device by helping support the person's body weight in hopes the patient can be more mobile. Lofstrand crutches, more commonly known as forearm crutches, consist of bands that encompass the forearms along with having handles for the patient to hold and rest his/her hands; the bands and hand rests act together to help support the patient's body weight. The forearm band has a quick release making it easy to take off the crutches when wanted or to relieve the forearms from damage if a fall occurs.
Forearm crutches are the preferred design of crutches in Europe, along with much of the rest of the world, while axillary (underarm) crutches are still more commonly used in the United States. One reason behind the lack of usage of forearm crutches in the United States could stem from the permanent connotation associated with forearm crutches in comparison to the indicated temporary usage of axillary crutches. Indeed, forearm crutches are a better solution for long-term usage patients. Several studies have shown that forearm crutches are less harmful to one's body.
== History ==
"Evidence from an Egyptian carving dating back to 2830 BC suggests that crutches have been used at least since the pharaohs ruled Egypt 5,000 years ago." 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. However, some modern inventor's have worked to develop innovative designs of this ancient assistive device in hopes to better address different types of patients.
In 1997, forearm crutches got a boost when President Bill Clinton started wearing them after tearing his right quadriceps tendon. He called the forearm crutches his "Stealth" crutches. In a news conference, Clinton said, "I think they were developed as an offshoot of B-2 technology... I like them quite a lot."〔
