What is the defining characteristic of a 'cumulative trauma disorder'?
Explanation
A cumulative trauma disorder (CTD) develops gradually as repeated microtrauma from force, repetition, and awkward postures accumulates faster than tissues can recover - distinct from an acute injury caused by a single event. It is not caused by one sudden impact, is not chemical, and is not limited to older workers. Gradual accumulation of microtrauma defines a CTD.
