hypo mobility

Question 1

hypo mobility

Answer 1

decreased mobility

mm shortening

Question 2

factors contributing hypomobility

Answer 2

immobilization 
extrinsic / int factors
posture
habits
aging

Question 3

contracture

Answer 3

shortening of mm unit around joint (loss ROM)

Question 4

5 types of contracture

Answer 4

myostatic
pseudomyostatic
arthrogenic
periartricular
fibrotic

Question 5

myostatic contracture

Answer 5

mm unit short

Question 6

pseudomyostatic

Answer 6

constant contraction (CNS lesion)

Question 7

arthrogenic

Answer 7

intra articular pathology

Question 8

periarticular

Answer 8

due to tissue crossing / attaching to joint

Question 9

fibrotic

Answer 9

adhesions / scar tissue

Question 10

flexibility

Answer 10

determines ROM without injury

Question 11

relative flexibility

Answer 11

stiffness in one mm group makes others compensate

Question 12

what happens to mm post immbolization

Answer 12

dec mm fibres cross sectional area, dec myofibrils, dec motor unit recruitment, mm weakness

Question 13

length tension relationship for shortening and lengthened position

Answer 13

short LEFT

length RIGHT

Question 14

effects of shortened position in immobilization

Answer 14

dec sarcomere,
mm shortens,
inc atrophy

Question 15

effects position of immobilization lengthened position

Answer 15

increased sarcomere

dec atrophy

Question 16

stretch weakness

Answer 16

weakness from mm in elongated position

Question 17

where is weakness in stretch weakness

Answer 17

mid and inner ROM

Question 18

adaptive shortening

Answer 18

tightness from mm in short position

Question 19

where is strength in adaptive shortening

Answer 19

inner ROM

Question 20

Impact of post immboization

Answer 20

mm
tendon
lig
articular car
bone

Question 21

what happens to 
tendon 
lig
cart
bone
post immobilziation

Answer 21

tendon - dec strength
lig - dec strength, stiff
cart - dec lube, soften
bon - dec mass

Question 22

effects of flexibility on aging

Answer 22

less tensile strength
less elastic
more adhesion

Question 23

acute effects stretch

Answer 23

mechanical and sensory theories

Question 24

mechanical theories of acute effect of stretch

Answer 24

mm length change due to elastic properties

Question 25

sensory theory of acute effect of stretch

Answer 25

increase stretch tolerance

Question 26

chronic effects of streching

Answer 26

elongation must use length connective tissue deformation

Question 27

any particular stretch method that works

Answer 27

nope

Question 28

is stretch tolerance inc only mech

Answer 28

no

Question 29

5 indications to stretch

Answer 29

``` limited ROM restricted ROM mm weakenss pre hab performance ```

Question 30

contraindications for stretch

Answer 30

``` bony end feel inflammation recent bony union instability surgeries ```

Question 31

precautions of stretching

Answer 31

recent steroid injection osteporosis frail recently immmobilzed (careful)

Question 32

things to consider when prescribing stretch

Answer 32

``` alignment stabilziaation intensity duration/ frequency speed of stretch mode of stretch ```

Question 33

T/f slow applied stretch more likely to active stretch reflex

Answer 33

false - less

Question 34

reasonable guideline to prescribe person

Answer 34

slow, low intensity 3-60 s . 2-4 reps | atlas 1 daily, most days of week
