Q

stretch weakness

A

weakness from mm in elongated position

17
Q

where is weakness in stretch weakness

A

mid and inner ROM

18
Q

adaptive shortening

A

tightness from mm in short position

19
Q

where is strength in adaptive shortening

A

inner ROM

20
Q

Impact of post immboization

A
mm
tendon
lig
articular car
bone
21
Q
what happens to 
tendon 
lig
cart
bone
post immobilziation
A

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

22
Q

effects of flexibility on aging

A

less tensile strength
less elastic
more adhesion

23
Q

acute effects stretch

A

mechanical and sensory theories

24
Q

mechanical theories of acute effect of stretch

A

mm length change due to elastic properties

25
Q

sensory theory of acute effect of stretch

A

increase stretch tolerance

26
Q

chronic effects of streching

A

elongation
must use length
connective tissue deformation

27
Q

any particular stretch method that works

A

nope

28
Q

is stretch tolerance inc only mech

A

no

29
Q

5 indications to stretch

A
limited ROM
restricted ROM
mm weakenss
pre hab
performance
30
Q

contraindications for stretch

A
bony end feel
inflammation
recent bony union
instability 
surgeries
31
Q

precautions of stretching

A

recent steroid injection
osteporosis
frail
recently immmobilzed (careful)

32
Q

things to consider when prescribing stretch

A
alignment
stabilziaation 
intensity 
duration/ frequency 
speed of stretch
mode of stretch
33
Q

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

A

false - less

34
Q

reasonable guideline to prescribe person

A

slow, low intensity 3-60 s . 2-4 reps

atlas 1 daily, most days of week

35

modes of stretching

A

active , passive

36
Q

active modes of stretching

A

dynamic, PNF, eccentric

37
Q

passive modes of stretching

A

static, partner, manual

38
Q

whats mechanical stretching

A

low load long duration , machine
