Exam Questions
Biomechanics of Human Movement
1. What is the primary function of the musculoskeletal system in
biomechanics?
A. Nutrient absorption
B. Force generation and transmission
C. Blood circulation
D. Nerve impulse conduction
Rationale: The musculoskeletal system generates and transmits forces for movement,
stability, and posture, foundational to biomechanics.
2. Which principle states that force equals mass times acceleration?
A. Hooke's Law
B. Newton's Second Law
C. Pascal's Principle
D. Archimedes' Principle
Rationale: Newton's Second Law (F = ma) is fundamental to understanding linear
, motion and force application in the body.
3. What is the role of the moment arm in torque production?
A. Reduces torque
B. Increases torque with greater perpendicular distance
C. Irrelevant to torque
D. Only applies to linear force
Rationale: Torque = force × moment arm (perpendicular distance from pivot), so
longer arms amplify rotational force.
4. What type of joint movement is flexion?
A. Rotation
B. Decreasing angle between two bones
C. Sliding
D. Spinning
Rationale: Flexion decreases the angle between bones (e.g., bending elbow), essential
for joint kinematics.
5. What is the primary purpose of joint ligaments?**
A. Muscle contraction
B. Limit excessive joint movement
C. Bone growth
D. Nerve protection
Rationale: Ligaments connect bones, providing stability and limiting hypermobility to
prevent injury.
Musculoskeletal Pathologies
6. What is the hallmark feature of osteoarthritis?
A. Systemic inflammation
B. Degenerative joint changes
C. Autoimmune destruction
D. Infectious etiology
Rationale: Osteoarthritis involves cartilage degeneration and osteophyte formation,
unlike inflammatory arthritides.
7. What is a common cause of rotator cuff tears?
A. Trauma
B. Chronic repetitive overhead motions
C. Genetic mutations
D. Nutritional deficiency
Rationale: Repetitive overhead activities (e.g., throwing) lead to degenerative tears in
the rotator cuff.
, 8. What is the primary pathology in rheumatoid arthritis?
A. Bone erosion only
B. Synovial inflammation and pannus formation
C. Muscle weakness
D. Tendon degeneration
Rationale: Rheumatoid arthritis is autoimmune, causing synovial inflammation and
pannus that erodes joint structures.
9. What is a common sequela of untreated scoliosis?
A. No complications
B. Rib hump and pulmonary restriction
C. Improved posture
D. Increased height
Rationale: Severe scoliosis causes rib deformity and reduced lung expansion, leading to
respiratory compromise.
10.What is the pathophysiological mechanism of tendinopathy?
A. Acute inflammation
B. Tendon degeneration and failed healing
C. Bone overgrowth
D. Muscle hypertrophy
Rationale: Tendinopathy involves collagen degeneration and eccentric loading, not
acute inflammation.
Gait Analysis
11.What is the stance phase of gait?
A. Swing leg forward
B. Foot in contact with ground
C. Initial heel strike
D. Toe-off only
Rationale: Stance phase (60% of gait cycle) is when the foot supports body weight.
12.What gait abnormality shows Trendelenburg sign?
A. Normal gait
B. Hip drop due to weak abductors
C. Shortened step length
D. Increased knee flexion
Rationale: Trendelenburg gait indicates gluteus medius weakness, causing
contralateral pelvic drop.
13.What is a common cause of antalgic gait?
A. Normal biomechanics
B. Pain avoidance
, C. Muscle weakness only
D. Nerve compression
Rationale: Antalgic gait shortens stance on the painful limb to minimize pain.
14.What phase of gait involves initial contact?
A. Mid-stance
B. Initial swing
C. Heel strike
D. Terminal stance
Rationale: Initial contact (heel strike) is the start of stance phase, absorbing impact.
15.What indicates a steppage gait?
A. Normal toe clearance
B. High step to compensate for foot drop
C. Prolonged stance
D. Reduced arm swing
Rationale: Steppage gait uses exaggerated hip flexion to clear a dropped foot due to
weakness or nerve damage.
Kinetic & Kinematic Assessments
16.What is kinematics?
A. Forces causing movement
B. Description of motion without forces
C. Muscle activation
D. Energy expenditure
Rationale: Kinematics studies motion (position, velocity, acceleration) without
considering causes (forces).
17.What is kinetics?
A. Motion patterns
B. Forces causing motion
C. Joint angles
D. Velocity only
Rationale: Kinetics examines forces (e.g., muscle tension, ground reaction) producing
motion.
18.What is Newton's Third Law in biomechanics?
A. Inertia
B. Equal and opposite reactions
C. Acceleration proportional to force
D. Action equals reaction
Rationale: For every action, there is an equal and opposite reaction, e.g., ground pushes
