A crutch is a mobility aid that transfers weight from the legs to the upper body. Often used by people who are not able to use their legs to support their weight, for reasons ranging from short-term to life-long disabilities. A lot of athletes tend to be in crutches do to injuries they encounter in everyday sports. The length of time they are required to use them depends on how sever their injury is or their rehabilitation time as well. When trying to figure out what is wrong with a patient an EMG analysis may be ran to measure the EMG odine. With an EMG measurement you are able to see what relevant for documentation of the response for the rehab programs, effects of physiotherapy and analyzing the muscle balance and activity (Airaksinen, 1998, p.1)
There are four types of crutches: Forearm, underarm, platform and leg support. The forearm crutch is used by inserting the arm into a cuff and holding the grip. The cuff, which is typically made of plastic or metal, can be a half-circle or a full circle with a V-type of opening in the front allowing the forearm to slip out in case of a fall. The underarm, which is also referred to as an axilla crutch, is used by placing the pad against the ribcage beneath the armpit and holding the grip, which is below and parallel to the pad. The platform is not used often by patients due to arthritis, cerebral palsy and other conditions. The arm rests on a grip, which, if properly designed, can be angled appropriately depending on the user’s disability. The leg support is commonly used when the user has an injury affecting one lower leg only. This device functions by strapping the affected leg into a support frame that simultaneously holds the lower leg clear of the ground while transferring the load from the group to the user’s knee or thigh. (Damm, 2012, p. 532) One of the pros of using this device is that the upper thigh atrophy is also reduced because the affected leg remains in use. When you have a pelvic, hip or thigh injury you are not able to use this product. A special designed crutch was made called the spring-load, where it provides forward velocity that correlates with the underarm crutch (Seeley, 2011, p.198). A lot of patients depend on ambulatory devices to be mobile in their daily living tasks and things they have to do. People have done many research studies where compare a spring-load crutch design and see if it provides better forward velocity. Several different gait patterns are possible, and the user chooses which one to use depending on the reason the crutches are needed (Matsuura, 2014, p.5). Patients typically load their affected leg while their using crutches rather than without (Damm, 2012, p.534). If a patient broke their ankle, they will have be in plaster and also on crutches for 6 weeks. Also gymnast who the length of time you keep using crutches depends on the severity of the injury.
