Classification of Injuries
![Page 2: 1 Classification of Injuries. Sign: a finding that is observed or that can be objectively measured (swelling, discoloration, deformity, crepitus) Sign.](https://reader033.fdocuments.us/reader033/viewer/2022051401/56649ec55503460f94bcfb96/html5/thumbnails/2.jpg)
Sign: a finding that is observed or that can be objectively measured (swelling, discoloration, deformity, crepitus)
Sign Versus SymptomSign Versus Symptom
Symptom: subjective complaint or an abnormal sensation that the patient describes but cannot be directly observed (pain, nausea, fatigue, altered sensation)
![Page 3: 1 Classification of Injuries. Sign: a finding that is observed or that can be objectively measured (swelling, discoloration, deformity, crepitus) Sign.](https://reader033.fdocuments.us/reader033/viewer/2022051401/56649ec55503460f94bcfb96/html5/thumbnails/3.jpg)
Acute: sudden onset and of short duration (one-time traumatic event or mechanism)
Acute Versus ChronicAcute Versus Chronic
Chronic: gradual onset and of prolonged duration (accumulation of minor insults or repetitive stress)
