The word ''crutch'' can also refer to anything used by a person for psychological or emotional support, or to something used as an excuse not to engage in normal life activities. ==Medical crutches== ===Types=== There are several different types of medical crutches: ; Forearm : Forearm crutches are the type most commonly used in [[Europe]], but in the [[United States]] are almost exclusively used by people with permanent [[disabilities]]. However, American orthopaedic surgeons are now beginning to prescribe forearm crutches for patients with shorter-term needs. Forearm crutches are used by slipping the arm into a cuff and holding the grip. The cuff, typically made of plastic or metal, can be a half-circle or a full circle with a V-type opening in the front allowing the forearm to slip out in case of a fall. [[Emile Schlick]], a French mechanical engineer, patented a walking stick (US patent number 1244249, filed Oct. 23, 1917) that provided an oblique support at the upper end for resting the forearm. This invention was first patented in France on May 7, 1915. [[Philipp Cederstom]] patented a similar-looking cane crutch (US Patent 2192766). Finally, the invention of [[A. R. Lofstrand, Jr.]], who filed a patent in 1945, consists of an adjustable-length crutch. In the US, forearm crutches are also sometimes referred to as ''Lofstrands'',<ref>Kluttz, Sherri L. 1998.

These are used by placing the pads against the rib cage beneath the armpits and holding the grip, which is below and parallel to the pad. These are sometimes known as ''axillary crutches''. ; Strutters : These are a variation on under-arm crutches, incorporating large soles which remain flat on the floor or ground while the user walks. They allow for an improved walking gait, and distribute body weight to reduce the risk of nerve damage caused by underarm crutches. ; Platform : These are less common and used by those with poor hand grip due to [[arthritis]], [[cerebral palsy]], or other condition. The arm rests on a horizontal platform and is strapped in place. The hand rests on a grip which, if properly designed, can be angled appropriately depending on the user's physical handicap. ; Knee Support : These crutches are useful for patients whose injury or disability is below the knee. They allow the knee of the injured leg to be placed on a support, so the injured leg now points backward behind the patient. This style of crutch affords the patient the ability to have one or both hands free to carry objects. Upper thigh [[atrophy]] is also reduced because lhalf the patients weight is now supported by each thigh rather than one thigh and the arms. ===Information on use === Several different [[human gait|gait]] patterns are possible, and the user chooses which one to use depending on the reason the crutches are needed. For example, a person with a [[leg]] injury generally performs a "swing-to" gait: lifting the injured leg, the patient places both crutches in front of himself, and then swings his uninjured leg to meet the crutches. Other gaits are used when both legs are equally affected by some disability, or when the injured leg is partially [[weight bearing]].<ref name="walkeasy-gaits">[http://www.walkeasy.com/interact/crutch_gait2.asp Walk Easy > Interact > Crutch Gait].
