Cumulative trauma disorders result from:

Cumulative trauma disorders (CTDs) arise from the accumulation of repetitive stress or minor injuries over time, leading to damage of muscles, tendons, nerves, and joints. These disorders typically develop gradually rather than from a single incident and can be caused by repetitive motions, awkward postures, or sustained pressure on specific body parts.

The nature of CTDs means they are often associated with jobs or activities that require the repetition of specific movements, such as typing, assembly line work, or similar tasks that put strain on certain areas of the body. The cumulative effect of these repeated minor injuries is what distinguishes CTDs from acute injuries, which occur from sudden overexertion or trauma. Understanding this distinction is crucial for recognizing risk factors, implementing proper ergonomic practices, and preventing such disorders in the workplace.
