Clinical Kinesiology

Question 1

Define kinesiology

Answer 1

study of human movement

Question 2

Define kinematics

Answer 2

motion/how a body moves

Question 3

Define kinetics

Answer 3

the forces associated with the motion of bodies in a frame of reference

Question 4

Directions of rotation

Answer 4

Flexion
Extension
Abduction
Adduction
Lateral flexion
Internal rotation
External rotation

Question 5

Directions of linear motion

Answer 5

Compression
Distraction
Translation
- anterior/posterior
- medial/lateral
- superior/inferior

Question 6

What direction is roll and slide moving in a convex-on-concave

Answer 6

roll and slide are opposite

Question 7

What direction is roll and slide moving in a concave-on-convex

Answer 7

roll and slide move in the same or similar direction

Question 8

What is close-packed position

Answer 8

the position of max congruence b/w articular surfaces and frequently a joint’s end of ROM

Question 9

What is loose (open)-packed position

Answer 9

any position that is not close-packed and relatively slack

Question 10

Define force

Answer 10

it causes a change in motion and induces deformation of the body it’s acting on

Question 11

Define property elasticity

Answer 11

if a load is exerted on an object then released the object will go back to its original position

Question 12

Define concentric contraction

Answer 12

muscle shortening (dominant internal torque)

Question 13

Define eccentric contraction

Answer 13

muscle lengthening (dominant external torque)

Question 14

Define isometric contraction

Answer 14

no length change (torques cancel)

Question 15

Define agonist

Answer 15

the primary muscle performing the action

Question 16

Define antagonist

Answer 16

the muscle that contradicts the primary muscle action

Question 17

Define stabilizer

Answer 17

a muscle that stabilizes the joint being displaced

Question 18

Define synergist

Answer 18

a muscle that assists the primary muscle in performing the action

Question 19

Define torque

Answer 19

rotational equivalent of force

Question 20

What is the most common lever class in the musculoskeletal system

Answer 20

3rd class levers

Question 21

Define mechanical disadvantage

Answer 21

muscle must produce greater relative forces

Question 22

Benefit of a mechanical disadvantage

Answer 22

less contraction distance required to produce joint displacement

Question 23

What is the relationship between load and velocity

Answer 23

higher the load the lower the velocity
