Section 1: Advanced Joint Mechanics and Arthrokinematics
Question 1
A patient with adhesive capsulitis demonstrates a capsular pattern of restriction at the glenohumeral
joint. Which arthrokinematic motion is MOST significantly impaired, and what is the mechanical
consequence?
A) Inferior glide of the humeral head; limited overhead reaching and rotation
B) Superior glide of the humeral head; increased subacromial space
C) Anterior glide of the humeral head; enhanced joint stability
D) Posterior glide of the humeral head; reduced joint congruency
Correct Answer: A
Rationale: Adhesive capsulitis ("frozen shoulder") primarily restricts inferior glide of the humeral head on
the glenoid fossa. This limitation impairs the arthrokinematic motion necessary for full elevation and
rotation, resulting in the characteristic capsular pattern of restriction where external rotation is most
limited, followed by abduction and internal rotation .
Question 2
During a rapid throwing motion, the humeral head must slide inferiorly on the glenoid to prevent
impingement. Which muscle group is primarily responsible for providing this dynamic stability?
A) Rotator cuff muscles (especially supraspinatus and infraspinatus)
B) Deltoid and pectoralis major
C) Latissimus dorsi and teres major
D) Biceps brachii and coracobrachialis
Correct Answer: A
Rationale: The rotator cuff muscles, particularly the supraspinatus and infraspinatus, work synergistically
to provide dynamic stabilization of the glenohumeral joint. During overhead activities, they help
maintain the humeral head centered in the glenoid fossa and control inferior glide to prevent
impingement of subacromial structures .
,Question 3
Which of the following BEST describes the concave-convex rule as applied to the tibiofemoral joint
during open-chain knee extension?
A) Convex tibial condyles roll anteriorly and glide posteriorly on concave femoral condyles
B) Convex femoral condyles roll anteriorly and glide posteriorly on concave tibial condyles
C) Convex tibial condyles roll posteriorly and glide anteriorly on concave femoral condyles
D) Convex femoral condyles roll posteriorly and glide anteriorly on concave tibial condyles
Correct Answer: B
Rationale: According to the concave-convex rule, when a convex surface (femoral condyles) moves on a
concave surface (tibial condyles), the roll and glide occur in the same direction. During open-chain knee
extension, the femoral condyles roll anteriorly and glide anteriorly on the tibial plateau .
Question 4
Which of the following arthrokinematic motions BEST describes the movement occurring at the
radiocarpal joint during wrist flexion?
A) Proximal row of carpal bones rolls and glides anteriorly
B) Proximal row of carpal bones rolls anteriorly and glides posteriorly
C) Distal row of carpal bones rolls and glides anteriorly
D) Radius rolls and glides anteriorly on the carpal bones
Correct Answer: B
Rationale: During wrist flexion, the proximal row of carpal bones (scaphoid, lunate, triquetrum) rolls
anteriorly and glides posteriorly on the radius. This arthrokinematic motion follows the concave-convex
rule and is essential for full wrist range of motion .
Question 5
Which of the following structures provides the primary restraint against anterior translation of the tibia
relative to the femur at 30 degrees of knee flexion?
A) Anterior cruciate ligament (ACL)
B) Posterior cruciate ligament (PCL)
C) Medial collateral ligament (MCL)
D) Iliotibial band
Correct Answer: A
Rationale: The anterior cruciate ligament (ACL) is the primary restraint against anterior tibial translation
at 30 degrees of knee flexion, providing approximately 85% of the restraining force. The ACL also
contributes to rotational stability and proprioception .
Question 6
A patient with chronic ankle instability demonstrates excessive inversion during gait. Which ligament is
,MOST likely injured, and what arthrokinematic alteration would result?
A) Anterior talofibular ligament; excessive anterior glide of the talus
B) Calcaneofibular ligament; excessive medial glide of the calcaneus
C) Posterior talofibular ligament; excessive posterior glide of the talus
D) Deltoid ligament; excessive lateral glide of the talus
Correct Answer: A
Rationale: The anterior talofibular ligament (ATFL) is the most commonly injured ligament during
inversion ankle sprains. Injury to this ligament leads to excessive anterior glide of the talus, contributing
to chronic instability and impaired ankle mechanics .
Question 7
Which of the following BEST describes the functional significance of the menisci during knee loading?
A) They increase joint congruity and distribute compressive loads over a larger surface area
B) They provide primary ligamentous stability to the knee
C) They generate synovial fluid for joint lubrication
D) They limit knee extension through mechanical blockage
Correct Answer: A
Rationale: The menisci increase joint congruity by deepening the tibial plateau and distributing
compressive loads over a larger surface area. They also provide shock absorption, joint lubrication, and
proprioception, significantly reducing contact stresses on articular cartilage .
Question 8
Which of the following arthrokinematic motions occurs at the facet joints of the lumbar spine during
forward flexion?
A) Superior articular facets glide inferiorly and posteriorly
B) Superior articular facets glide superiorly and anteriorly
C) Inferior articular facets glide inferiorly and anteriorly
D) Inferior articular facets glide superiorly and posteriorly
Correct Answer: D
Rationale: During forward flexion of the lumbar spine, the inferior articular facets of the superior vertebra
glide superiorly and posteriorly on the superior articular facets of the inferior vertebra. This
arthrokinematic motion allows for controlled flexion while maintaining facet joint integrity .
Question 9
Which of the following BEST describes the closed-packed position of the knee joint?
A) Full extension with lateral rotation of the tibia
B) 90 degrees of flexion with medial rotation of the tibia
, C) Full extension with medial rotation of the tibia
D) 30 degrees of flexion with neutral rotation
Correct Answer: A
Rationale: The closed-packed position of the knee is full extension with lateral (external) rotation of the
tibia. In this position, the joint surfaces are maximally congruent, and the ligaments are taut, providing
maximum stability. This is the position of the screw-home mechanism .
Question 10
Which of the following articular surfaces is classified as an ovoid joint, and what type of motion does it
permit?
A) Glenohumeral joint; multiaxial ball-and-socket motion
B) Tibiofemoral joint; uniaxial hinge motion
C) Radiocarpal joint; biaxial condyloid motion
D) First carpometacarpal joint; biaxial saddle motion
Correct Answer: C
Rationale: The radiocarpal (wrist) joint is an ovoid condyloid joint that permits biaxial motion
(flexion/extension and radial/ulnar deviation). Ovoid joints have one convex and one concave articular
surface, allowing movement in two planes with limited rotation .
Section 2: Muscle Architecture and Force Production
Question 11
A sprinter performs a 100-meter dash. Which muscle fiber type is predominantly recruited, and what
metabolic pathway is primarily utilized?
A) Type I slow-twitch fibers; oxidative phosphorylation
B) Type IIa fast-twitch oxidative fibers; both oxidative and glycolytic pathways
C) Type IIx fast-twitch glycolytic fibers; anaerobic glycolysis
D) Type I and Type IIa fibers equally; aerobic metabolism
Correct Answer: C
Rationale: Type IIx (fast-twitch glycolytic) fibers are predominantly recruited during maximal sprinting
due to their rapid force production and reliance on anaerobic glycolysis. These fibers have high ATPase
activity and large cross-sectional area but fatigue quickly due to limited oxidative capacity .
Question 12
Which of the following BEST describes the concept of pennation angle in skeletal muscle, and how
does it affect force production?
A) Pennation angle increases as muscle contracts, reducing force production
