Which condition represents a cumulative musculoskeletal disorder from repeated mechanical stress?

• A. Psychological Risk Factors
• B. Ganglion
• C. Shoulder Tendonitis
• D. Work Related Musculoskeletal Disorders

Answer: (D)

Repeated mechanical stress at work can lead to work-related musculoskeletal disorders, which describe cumulative injuries to muscles, tendons, nerves, and joints over time. These conditions arise from ongoing exposures such as repetitive motions, forceful exertions, awkward postures, or vibration, and they gradually develop as microtrauma accumulates, leading to pain, weakness, or functional limitations.

A psychological risk factor is unrelated to physical tissue damage, a ganglion is a cyst, and shoulder tendonitis is a specific inflammation that can result from overuse but does not itself denote the broader category of cumulative work-related musculoskeletal disorders.
