Which tissue type has the lowest blood supply and therefore the slowest healing rate after ergonomic injury?
Answer: Tendon
Tendons are avascular tissues with poor blood supply, resulting in very slow healing rates compared to muscle or bone.
The NIOSH Lifting Equation uses a Recommended Weight Limit (RWL). What is the load constant (LC) used in the equation?
Answer: 23 kg
The NIOSH Lifting Equation uses a load constant of 23 kg (51 lbs), which is the maximum weight recommended under ideal conditions.
Which biomechanical model calculates compressive forces on the L5/S1 disc by treating the spine as a simple lever?
Answer: Static biomechanical model
The static biomechanical model uses lever mechanics to estimate compressive and shear forces at the L5/S1 intervertebral disc.
Carpal tunnel syndrome results from compression of which nerve?
Answer: Median nerve
Carpal tunnel syndrome is caused by compression of the median nerve as it passes through the carpal tunnel in the wrist.
What is the NIOSH Action Limit (AL) for back compressive force at L5/S1?
Answer: 3,400 N
NIOSH sets the action limit at 3,400 N of compressive force at L5/S1, above which musculoskeletal injury risk increases significantly.
Which of the following is a primary risk factor for work-related upper extremity musculoskeletal disorders (WRUEMSDs)?
Answer: Repetitive motion combined with forceful exertion
The combination of repetitive motion and forceful exertion is a leading biomechanical risk factor for WRUEMSDs such as tendinitis and CTS.
