OMT Kinesiology & Biomechanics 3

Question 1

In orthopedic massage, understanding the closed-packed position of a joint is important because in this position the joint is:

Accepted Answer

Most congruent with maximum ligamentous tension

Answer

Most accessible for joint mobilization

Answer

Least painful for the patient

Answer

Most relaxed with slack capsule

Question 2

Which kinematic concept describes the motion of one joint surface rolling and sliding on the opposing surface simultaneously?

Accepted Answer

Arthrokinematics

Answer

Osteokinematics

Answer

Synarthrodial motion

Answer

Triplanar motion

Question 3

According to the convex-concave rule in joint mobilization, when a convex surface moves on a fixed concave surface, the roll and slide occur in which directions?

Accepted Answer

Opposite directions

Answer

Same direction

Answer

Roll only, no slide

Answer

Slide only, no roll

Question 4

A therapist assesses 'length-tension relationship' when evaluating a muscle. What does this term describe?

Accepted Answer

The relationship between muscle resting length and its force-generating capacity

Answer

The maximum tensile force a muscle can withstand before tearing

Answer

The time required for a muscle to generate peak tension

Answer

The ratio of agonist to antagonist force production

Question 5

Which biomechanical principle explains why the lumbar spine is at greatest risk for injury during combined flexion, lateral flexion, and rotation?

Accepted Answer

Coupling motion and triaxial loading

Answer

Wolff's Law

Answer

Davis's Law

Answer

Bernoulli's principle

Question 6

Which concept in kinesiology refers to the muscle's ability to maintain a contraction at a constant length without joint movement?

Accepted Answer

Isometric contraction

Answer

Isotonic contraction

Answer

Isokinetic contraction

Answer

Auxotonic contraction

Question 7

During functional assessment of gait, excessive anterior pelvic tilt is most commonly associated with weakness or tightness in which muscle group combination?

Accepted Answer

Weak abdominals and hip extensors with tight hip flexors and lumbar extensors

Answer

Weak hip flexors and tight hip extensors

Answer

Weak hip abductors and tight adductors

Answer

Weak quadriceps and tight hamstrings
