Question 12

How many degrees of freedom does the hip have and why?

Answer 12

3 because it is a triaxial joint

Question 13

How many degrees of freedom does the knee have and why?

Answer 13

2, it’s a biaxial joint (flex/ext and tibial rotation)

Question 14

How many degrees of freedom do the interphalangeal joints of fingers have and why?

Answer 14

1, it’s a uniaxial joint (flex/ext)

Question 15

Describing the kinetic chain of a movement describes what concept of Kinematics?

Answer 15

Osteokinematics

Question 16

A back squat is an example of a closed or open kinetic chain? Why?

Answer 16

Closed

Distal segment is fixed, proximal is moving

Question 17

Bicep curl is an example of a closed or open kinetic chain? Why?

Answer 17

Open

Distal segment is moving proximal segment is fixed

Question 18

Describing the motion occurring between joint surfaces is describing the …..

Answer 18

Arthrokinematics

Question 19

Benefits of a convex-concave relationship include…

Answer 19

Improve joint congruency
Increases surface area for dissipating contact forces
Helps guide motion between bones

Question 20

Roll, spin, and glide describe

Answer 20

Arthrokinematics

Question 21

What is joint play and why is it assessed

Answer 21

Accessory motion, determines health of the joint

Question 22

Roll without glide in the shoulder results in ___ _____ of the humeral head. This can cause ___

Answer 22

Superior migration

Impingement

Question 23

Describe the Arthrokinematics of pronation

Answer 23

Concave radius spins on convex capitulum of humerus

Question 24

What is determined by the convex-concave rule? Describe the rule

Answer 24

Glide (Roll and spin are usually the same as the Osteokinematics)

Convex-concave= glide is in opposite direction
Concave-convex= glide is in the same direction

Question 25

Loose vs closed packed is descriptor of kinetics or Kinematics

Answer 25

Kinematics

Question 26

The position where a joint has max congruence and min accessory movement is called what? Where is it usually found?

Answer 26

Closed packed | Toward end range whee ligaments and capsule are taunt and the joint is stable

Question 27

The position where the joint is least congruent and accessory motion is maximal is called what? Where can it be found

Answer 27

Loose-packed | Near midrange where ligaments and capsule are on slack

Question 28

Why do we need to know closed and loose packed positions?

Answer 28

To show the vulnerability of a joint and assess accessory motion

Question 29

How does joint position influence manual therapy techniques?

Answer 29

Performing manipulation in a loose packed position by allowing more space for movement

Question 30

A push or pull that produces, arrests or modifies movement describes

Answer 30

Force

Question 31

Why might a muscle not be able to resist force?

Answer 31

Weakness caused by: Trauma Disease Prolonged disuse

Question 32

Types of force/load applied to the MSK system

Answer 32

``` Tension Compression Bending Shear Torsion Combined loading ```

Question 33

The toe region in the stress-strain curve shows us what?

Answer 33

That an area must be drawn taut before tension can be measured

Question 34

When slack is taken off of a tissue, stress and strain have what relationship?

Answer 34

Linear

Question 35

What is the difference between the elastic and plastic regions of the stress-strain curve?

Answer 35

When in the elastic region, tissue will return to original length after being stretched. When in the plastic region, tissue undergo physiological changes in response to being stretched.

Question 36

Tissues with high velocity have

Answer 36
