Tendinitis is best characterized as inflammation of which structure?
Answer: Tendon sheath or tendon itself
Tendinitis refers to inflammation of the tendon or its surrounding sheath, commonly caused by repetitive overuse movements.
In the context of manual material handling, what does the Lifting Index (LI) represent?
Answer: The ratio of actual load to the RWL
The Lifting Index is calculated by dividing the actual load lifted by the Recommended Weight Limit, indicating relative injury risk.
Which joint posture places the greatest compressive force on the intervertebral discs?
Answer: Trunk flexion greater than 45 degrees
Trunk flexion greater than 45 degrees dramatically increases disc compressive and shear forces, especially at L5/S1.
De Quervain's tenosynovitis specifically affects which tendons?
Answer: Abductor pollicis longus and extensor pollicis brevis
De Quervain's tenosynovitis is inflammation of the abductor pollicis longus and extensor pollicis brevis tendons at the wrist's radial side.
What does the term 'cumulative trauma disorder' (CTD) imply about the cause of injury?
Answer: Gradual tissue damage from repeated low-level exposures over time
CTDs develop from repetitive micro-traumas that accumulate over time when tissue damage occurs faster than the body can repair.
Which factor does NOT directly increase the biomechanical stress of a manual lift?
Answer: Eye color of the worker
Eye color is a personal characteristic unrelated to biomechanical stress; horizontal distance, frequency, and twisting all amplify spinal loading.
