An elastic bandage applied circumferentially to the upper or lower limb, specifically the region extending from the shoulder to the wrist, serves to provide graduated external pressure. This type of medical device is commonly used to manage swelling, provide support, and improve circulation in the applied limb. Examples include applying it after an injury, such as a sprain or strain, to reduce edema formation.
The practice of applying external pressure to limbs for therapeutic purposes dates back centuries. Modern applications leverage advancements in materials science to provide consistent and controlled pressure. This modality aids in lymphatic drainage, reduces the risk of blood clot formation (deep vein thrombosis), and supports muscle function, particularly during physical activity. Furthermore, the support offered can help prevent re-injury by limiting excessive movement.
