The term 'immobilised' can be defined as being DISABLED or PARALYSED. It is a condition in which a person or animal is unable to move or control their body due to an injury, illness, or other physical impairment. This can be caused by a variety of factors, including trauma, nerve damage, and muscle weakness. Immobilisation can also be used as a form of medical treatment, such as when a patient is placed in a cast or splint to help heal a broken bone. In some cases, immobilisation can be permanent, while in others it can be temporary.
