Final answer:
The primary factors affecting the development of Cumulative Trauma Disorder include the intensity of force applied, repetitiveness of task, and lack of proper rest period, but not the age of the worker.
Step-by-step explanation:
The primary factors that affect the development of Cumulative Trauma Disorder (CTD) include factors such as the intensity of force applied, repetitiveness of task, and lack of a proper rest period. However, when looking at the options provided (A) Age of the worker, (B) Intensity of force applied, (C) Repetitiveness of task, and (D) Lack of a proper rest period, we can determine that the age of the worker is not a primary factor affecting the development of CTD but rather an associated risk factor. This is because CTDs are more related to the conditions of the task being performed than the intrinsic factors of the worker themselves, like age.
To elaborate with examples, the padding of a strained muscle is part of the typical treatment to reduce inflammation and provide support to the affected area. If someone repeatedly uses a jackhammer, they are most likely to develop Carpal tunnel syndrome, which is a type of CTD caused by the repetitive strain on the wrist. On the subject of occupational health, factors like job strain and workstation ergonomics (such as the height of a chair in an office) are critical in preventing job burnout and musculoskeletal disorders respectively.
