Lecture 1: Posture Flashcards
Benefits of optimal posture
less energy
reduce stress on structure
What does a brief visual check include
head entered shoulder line iliac crest line spinal curves thorax over pelvis feet hip width weight bearing
Name 3 structures plumb line goes through
external auditory meatus, spine, greater trochanter,
What is equilibrium
line of gravity through joint axis
T/F torque can be generated by passive and active tissues
True
LOG Ankle
LOG Knee
LOG Hip
Ankle: Anterior
Knee: Anterior
Hip: Posterior
LOG to T spine specifically
anterior
C/L Spine is right through
Where is moment greatest on each curve
Apex (C4/5, T6, L3)
4 static stabilizers
ligs, fascia, bones, joints
dynamic stabilizers
tissue, posture mm
3 ways we maintain body alignment
static, dynamic stabilizers, neural control
how does neuro control help body alignment
coordinates, anticipates , stiffens
Postural fault
deviates from norm, no structural limitation
results of postural fault
more energy, more stress structures
postural pain syndrome
pain from mechanical stress, bad position long time
postural dysfunction
tissue adapts and gets weak because bad habits / position after surgery
where does pain come from
structures and nerve endings
Common postural faults
genu recurvatum, exaggerated lumbar lordosis, exaggerated thoracic kyphosis sway back, flat back, head forward posture, p es caves/planus, hallux valgus, scoliosis
causes gene recurvatum
stretched posteriors (hamstrings)
causes exaggerated lumbar lordosis
posture habits / pregs
weak abs, short hip flexors, narrow IVF
causes sway back
hip joint dysfunction (lumbar lordosis, and thoracic kyphosis)
causes flat back
ergonomics, short abs / hip extensors
causes exaggerated thoracic kyphosis
disease, ergonomics, tight pecs
causes head forward posture
posture, short SCM
functional scoliosis
due to extra spinal source, resoloves
leg length
structural scoliosis
idiopathic
COG on kids
T12
T?F greater lumbar lordosis kids
yes
Varus or valgus first for kids
varus
is pes planusnormal kids
yes
posture on older adults
less strength, delayed balance, spinal degeneration (alignment changes) thoracic kyphosis (hunch)
posture on pregs
more lumbar lordosis, thoracic kyphosis, foot pronation
