A chronic injury is defined as:

A chronic injury is defined as:

• A. An injury caused by low-intensity, long-duration forces (e.g., tendinitis or bursitis) or a recurring acute injury.
• B. An injury from a single high-impact event.
• C. An injury that resolves within 24 hours.
• D. An injury with no inflammatory component.

Answer: (A)

Chronic injuries arise from repetitive or cumulative stress on tissues, or from recurring injuries, causing symptoms that persist and heal more slowly than with an acute event. The idea is that low-load, long-duration forces wear tissues down over time, or repeated episodes prevent complete restoration between episodes. That’s why describing a chronic injury as one caused by low-intensity, long-duration forces (such as tendinopathy or bursitis) or as a recurring acute injury best captures the persistent, overuse pattern and extended healing timeline that define chronic conditions. In contrast, a single high-impact event produces an acute injury with a clear onset; an injury that resolves within a day is typical of minor acute injuries; and saying there’s no inflammatory component oversimplifies chronic injuries, which are defined by duration and pattern of loading rather than a blanket inflammatory status.
