Which kind of trauma is classified as microtrauma?

• A. Acute injuries
• B. Chronic injuries
• C. Sudden injuries
• D. Organic injuries

Answer: (B)

Microtrauma occurs when small, repetitive stresses build up in a tissue faster than it can repair, so the damage accumulates over time. When this process continues, the resulting injury tends to present as a chronic overuse condition rather than a single, isolated event. That’s why the best answer is chronic injuries: they reflect the long-standing, gradual onset that comes from repeated loading and insufficient recovery, rather than a one-time incident. Acute injuries arise from a single, sudden force and show immediate onset of pain and dysfunction, which is not how microtrauma behaves. Organic injuries imply a clear, identifiable structural pathology from a specific event; microtrauma is about the cumulative effect of repetitive stress, which often lacks a single defining event and manifests gradually as a chronic issue.
