Principles of Biomechanics, Osteo/Arthrokinematics

Question 1

What is biomechanics?

Answer 1

The study of the mechanisms of anatomical movement

Question 2

What is kinesiology?

Answer 2

The study of human movement

Question 3

What is osteokinematics?

Answer 3

Motion you see, observable movements of the bones, shown by a change in the joint angle.

Question 4

What is arthrokinematics?

Answer 4

Motion you feel, unobservable accessory motion between adjacent joint spaces.

Question 5

What is arthrokinematics necessary for?

Answer 5

full, pain free range of motion

Question 6

When does arthrokinematics happen?

Answer 6

during all active and passive motion

Question 7

True or Fasle: Arthrokinematic motion can occur independently or voluntarily

Answer 7

False

Question 8

True or False: Arhtrokinematic motion if restricted, can limit physiological movement.

Answer 8

True

Question 9

What is joint play?

Answer 9

Passive joint movement that can’t be achieved by active contraction

Question 10

What is component movement?

Answer 10

Involuntary obligatory joint motion occurring outside the joint that accompanies active motion

Question 11

What is adhesive capsulitis (AC)?

Answer 11

Painful and progressively restricted active and passive glenohumeral joint range of motion. Loss of more than 25% shoulder ROM in at least two directions, usuallyabduction and external rotation.

Question 12

What is another name for adhesive capsulitis (AC)?

Answer 12

Frozen shoulder

Question 13

What is an arthrokinematic roll?

Answer 13

When new points on one joint surface come into contact with new points on the other surface (wheel)

Question 14

Rolling occurs when the two articulating surfaces are ______________.

Answer 14

incongruent

Question 15

What is an arthrokinematic glide?

Answer 15

When one constant point on one surface is contacting new points or a series of points on the other surface (braking)

Question 16

When does gliding occur?

Answer 16

When the two surfaces are congruent

Question 17

What is an arthrokinematic spin?

Answer 17

rotation around a stationary longitudinal axis (loss of traction)

Question 18

True or False: All motions require rolling and gliding to occur simultaneously.

Answer 18

True

Question 19

The more congruent the more ____________

The more incongruent the more ___________

Answer 19

gliding; rolling

Question 20

What are the 4 types of joint surfaces?

Answer 20

convex; concave; sellar; ovoid

Question 21

What is an ovoid joint shape?

Answer 21

A joint with concave and convex articulating shapes

Question 22

What is a sellar joint shape?

Answer 22

A saddle shape with each articular surface having a concave and convex component in a specific direction

Question 23

Where do convex surfaces have more cartilage?

Answer 23

The center

Question 24

Where do concave surfaces have more cartilage?

Answer 24

the periphery

Question 25

When the concave surface is stationary and convex surface moves. Osteo and arthokinematic motion is in the ____________ direction.

Answer 25

opposite

Question 26

When Convex surface is stationary and concave surface moves Osteo and Arthrokinematic motion is _______ direction. In the Arthrokinematic mobilization Glide and Roll are in the _______ direction

Answer 26

same

Question 27

Arthrokinematic ________ always occurs in the same direction as bone movement.

Answer 27

Roll

Question 28

What is open (loose) packed position of a joint and what is it used for?

Answer 28

Position with least amount of joint surface congruency, mobilization/manipulation.

Question 29

In open packed position joint play is _____________ and capsule and support ligaments are_________.

Answer 29

maximized; lax

Question 30

What is closed packed position and what is it used for?

Answer 30

Position with the most amount of joint congruency; special tests

Question 31

In closed packed position joint play is _____________ and capsule and support ligaments are_________.

Answer 31

minimized(non-existent); Maximally tight

Question 32

What is a capsular pattern of restriction?

Answer 32

What is a capsular pattern of restriction?

Question 33

What is a noncapsular pattern of restriction?

Answer 33

A limitation in any pattern other than capsular.
