Which term describes illnesses that develop gradually over time from repeated mechanical stresses?

• A. Tendonitis
• B. Work Related Musculoskeletal Disorders
• C. Epicondylitis
• D. De Quervain's Tenosynovitis

Answer: (B)

Work Related Musculoskeletal Disorders describe illnesses that develop gradually over time from repeated mechanical stresses in the workplace, such as repetitive motions, awkward postures, or sustained forces. This umbrella term captures how small, cumulative strains accumulate and lead to symptoms like pain, weakness, or reduced motion, rather than a single acute injury. The other terms refer to specific conditions: tendonitis is inflammation of a tendon, often from overuse but not the broad category; epicondylitis is a particular tendon problem at the elbow; and De Quervain's tenosynovitis is a specific tenosynovitis at the thumb/wrist. So the best descriptor for illnesses that arise gradually from repeated mechanical stresses is Work Related Musculoskeletal Disorders.
