hypo mobility Flashcards
hypo mobility
decreased mobility
mm shortening
factors contributing hypomobility
immobilization extrinsic / int factors posture habits aging
contracture
shortening of mm unit around joint (loss ROM)
5 types of contracture
myostatic pseudomyostatic arthrogenic periartricular fibrotic
myostatic contracture
mm unit short
pseudomyostatic
constant contraction (CNS lesion)
arthrogenic
intra articular pathology
periarticular
due to tissue crossing / attaching to joint
fibrotic
adhesions / scar tissue
flexibility
determines ROM without injury
relative flexibility
stiffness in one mm group makes others compensate
what happens to mm post immbolization
dec mm fibres cross sectional area, dec myofibrils, dec motor unit recruitment, mm weakness
length tension relationship for shortening and lengthened position
short LEFT
length RIGHT
effects of shortened position in immobilization
dec sarcomere,
mm shortens,
inc atrophy
effects position of immobilization lengthened position
increased sarcomere
dec atrophy
stretch weakness
weakness from mm in elongated position
where is weakness in stretch weakness
mid and inner ROM
adaptive shortening
tightness from mm in short position
where is strength in adaptive shortening
inner ROM
Impact of post immboization
mm tendon lig articular car bone
what happens to tendon lig cart bone post immobilziation
tendon - dec strength
lig - dec strength, stiff
cart - dec lube, soften
bon - dec mass
effects of flexibility on aging
less tensile strength
less elastic
more adhesion
acute effects stretch
mechanical and sensory theories
mechanical theories of acute effect of stretch
mm length change due to elastic properties
sensory theory of acute effect of stretch
increase stretch tolerance
chronic effects of streching
elongation
must use length
connective tissue deformation
any particular stretch method that works
nope
is stretch tolerance inc only mech
no
5 indications to stretch
limited ROM restricted ROM mm weakenss pre hab performance
contraindications for stretch
bony end feel inflammation recent bony union instability surgeries
precautions of stretching
recent steroid injection
osteporosis
frail
recently immmobilzed (careful)
things to consider when prescribing stretch
alignment stabilziaation intensity duration/ frequency speed of stretch mode of stretch
T/f slow applied stretch more likely to active stretch reflex
false - less
reasonable guideline to prescribe person
slow, low intensity 3-60 s . 2-4 reps
atlas 1 daily, most days of week
modes of stretching
active , passive
active modes of stretching
dynamic, PNF, eccentric
passive modes of stretching
static, partner, manual
whats mechanical stretching
low load long duration , machine
