Recently I had a student on a course talk about a fourth way to identify a victim of a stroke. I had never come across this before so i was intrigued. During an emergency phone call the ambulance service asked the caller to ask the stroke victim to stick their tongue out for the family which fell to the left. Although in this instance it helped the family to identify the stroke it is not a universal method of identifying a stroke. I have attached the recognised UK NHS advice with the Internet link. In first aid we are expected to follow set procedures, however little tricks like this used at the same time as the recognised procedures can sometimes help in your diagnosis.
