Thoracic outlet syndrome (TOS) involves compression of neurovascular structures in which anatomical area?
Answer: Space between the clavicle and first rib
TOS occurs when nerves, arteries, or veins are compressed in the thoracic outlet between the clavicle and first rib.
Which muscle group is primarily responsible for stabilizing the lumbar spine during lifting tasks?
Answer: Erector spinae and multifidus
The erector spinae and multifidus muscles work synergistically to stabilize and extend the lumbar spine during lifting.
What is 'contact stress' in ergonomics?
Answer: Localized mechanical pressure on soft tissue from hard surfaces or edges
Contact stress occurs when a hard surface or edge concentrates mechanical pressure on a small area of soft tissue, impairing circulation and nerve function.
Epicondylitis (tennis or golfer's elbow) involves inflammation at which anatomical site?
Answer: Medial or lateral epicondyle of the humerus
Epicondylitis affects the tendons attached to the medial (golfer's) or lateral (tennis) epicondyle of the humerus at the elbow.
Which posture assessment tool specifically accounts for both upper and lower body posture including load and activity type?
Answer: REBA
REBA (Rapid Entire Body Assessment) evaluates whole-body posture including upper and lower extremities, load handled, and activity level.
What is the primary purpose of the Strain Index (SI) in ergonomics?
Answer: Quantify risk of distal upper extremity disorders from job tasks
The Strain Index quantifies risk for distal upper extremity MSDs by rating six task variables including intensity of exertion and hand posture.
