What is a 'sign' in the context of injury assessment?

In the context of injury assessment, a 'sign' refers to observable and measurable evidence of injury or illness. This can include physical findings that can be seen, felt, or quantified by a healthcare professional during a clinical evaluation. Examples of signs might include swelling, bruising, abnormal range of motion, or specific medical test results that indicate the presence of an injury.

The emphasis on objective data is crucial; signs are distinct from symptoms, which are subjective experiences conveyed by the patient, such as pain or fatigue. Understanding that signs are factual measurements or observations helps professionals in diagnosing and determining the best course of treatment. The ability to assess and document these signs accurately is critical in sports medicine, particularly in creating effective rehabilitation plans and monitoring recovery progress.
