General assesment

Question 1

3 things in an anatomical lever

Answer 1

• fulcrum
• levers
• forces

Question 2

what is the muscle force arm

Answer 2

Distance from muscle insertion to joint

Question 3

1st class levers

Answer 3

applied force and resistance are on opposite sides of the fulcrum

Question 4

2nd class lever

Answer 4

resistance lies between the applied force and fulcrum

Question 5

3rd class levers

Answer 5

the force is applied between the resistance and the fulcrum

Question 6

Ex of 3rd class lever

Answer 6

biceps brachii - most in the body

Question 7

as kin what do we need to know in movement testing

Answer 7

1. aRom
2. pROM
3. manual m testing
4. joints above and below
5. refer on

Question 8

isometric contractions test what

Answer 8

contractile tissue

Question 9

passive movements test what

Answer 9

inert and contractile structures

Question 10

when inert tissue is injured where will pain be perceived

Answer 10

active and passive movements in same direction

Question 11

if injured this movement should give inert tissue a pain free sensation

Answer 11

isometric restricted movements

Question 12

what affects range of motion

Answer 12

• age
• gender
• pregnant

Question 13

pRom is done before aRROM

Answer 13

false

Question 14

pROM provides info regarding

Answer 14

• end-feels
• structure integrity
• capsular patterns

Question 15

join ROM that is greater then normal is —

Answer 15

hyper mobility

Question 16

joint ROM that is lesser then normal is —

Answer 16

hypomobility

Question 17

what is a capsular pattern

Answer 17

• joint specific
• indicate irritation of the whole capsule
• typically due to degenerate disease, immobilization or inflammation

Question 18

you’d feel a capsular pattern when assessing what

Answer 18

pROM

Question 19

what is passive insufficiency

Answer 19

Occurs with 2 joint muscles and refers to the fact that these muscles cannot stretch maximally across both joints at the same time

Question 20

what is active insufficiency

Answer 20

2+ joint muscles cannot contract maximally across both joints at the same time

Question 21

what is an isometric contraction

Answer 21

muscle is activated, no movement

Question 22

what is a concentric movement

Answer 22

activated muscle and shortens

Question 23

eccentric movement

Answer 23

muscle is activated and legnthens

Question 24

Isokinetic movement

Answer 24

rate of moment is constant

Question 25

isotonic movement

Answer 25

Resistance is constant

Question 26

what are agonists and antagonists

Answer 26

agonist - prime mover - produces concentric and eccentric movement antagonist - opposite motion of agonist - passively elongates/shortens

Question 27

fiber organization- length or fibres in series provide a muscle with what

Answer 27

more mobility - impacts speed of motion

Question 28

fibers in parallel are associated with what

Answer 28

greater force production - shorter = stability

Question 29

load velocity relation - with increase velocity of shortening ...

Answer 29

force decliens

Question 30

load velocity relation - with increase velocity of lengthening....

Answer 30

force increases

Question 31

Where in a joints’ range of motion is the potential torque production the greatest?

Answer 31

the mid range

Question 32

what does tension depend on?

Answer 32

filament overlap and sarcomere length

Question 33

if contractile tissue is strong but painful this indicates what..

Answer 33

contractile lesion grade 1 muscle strain

Question 34

if contractile tissue is weak and painful this indicates what..

Answer 34

grade 2 muscle strain

Question 35

a grade 3 contractile structure rupture would show as what when testing the muscle

Answer 35

contractile tissue is weak and painfree

Question 36

an upper motor neuron lesion we would see this response from a reflex..

Answer 36

reflex is intact but is exaggerated

Question 37

an lower motor neuron lesion we would see this response from a reflex..

Answer 37

absent or under exaggerated

Question 38

Give an example of active insuffisiency

Answer 38

when you make a fist in neutral vs making a fuss with your wrist flexed - finger flexors cannot shorten any more.

Question 39

give an example of passive insufficiency

Answer 39

when you attempt hip flexion with legs extended, hamstrings passively effect this because they can't be stretched any more.
