CPE CPE Biomechanics & Musculoskeletal Disorders Questions and Answers 2

Question 1

Tendinitis is best characterized as inflammation of which structure?

Accepted Answer

Tendon sheath or tendon itself

Answer

Tendinitis refers to inflammation of the tendon or its surrounding sheath, commonly caused by repetitive overuse movements.

Question 2

In the context of manual material handling, what does the Lifting Index (LI) represent?

Accepted Answer

The ratio of actual load to the RWL

Answer

The Lifting Index is calculated by dividing the actual load lifted by the Recommended Weight Limit, indicating relative injury risk.

Question 3

Which joint posture places the greatest compressive force on the intervertebral discs?

Accepted Answer

Trunk flexion greater than 45 degrees

Answer

Trunk flexion greater than 45 degrees dramatically increases disc compressive and shear forces, especially at L5/S1.

Question 4

De Quervain's tenosynovitis specifically affects which tendons?

Accepted Answer

Abductor pollicis longus and extensor pollicis brevis

Answer

De Quervain's tenosynovitis is inflammation of the abductor pollicis longus and extensor pollicis brevis tendons at the wrist's radial side.

Question 5

What does the term 'cumulative trauma disorder' (CTD) imply about the cause of injury?

Accepted Answer

Gradual tissue damage from repeated low-level exposures over time

Answer

CTDs develop from repetitive micro-traumas that accumulate over time when tissue damage occurs faster than the body can repair.
