Immobilization refers to the process of stopping something or someone from moving. It can be achieved through mechanical means, such as braces or casts, or by strict bed rest. Immobilization can also refer to the restraint of an animal by keeping it or parts of it in a comfortable but safe hold by hand or by means of a physical device. In medicine, immobilization can be used as a treatment for certain diseases, such as tuberculosis, by prescribing quiet rest in bed for a prolonged period. Immobilization can also refer to the act of preventing the use, activity, or movement of something or someone.
