ch8: assessment of body alignment, posture and gait Flashcards
(31 cards)
somatotyping layers
3 germ layers of embryonic dev
-endoderm: dev into digestive tract
- mesoderm: muscle, heart, bld vesssels
- ectoderm: skin and nervous system
somatotypes
ectomorph: small delicate frame, fat chest, thin, small sh, lean m, mass, hard to gain weight, fast metablism
- mesomorph: athletic, gen hard body, well-defined m., rectangular body shape, strong, gain m. easily, gain fat more easily then ectomorph
- endomorph: soft and round body, gain m. and fat easily, generaly short, stocky build, round physique, slow metabolism
3 main purpose of posture control
- antigravity func: maintaining an erect posture and keeping eyes level
- maintenance of equilibrium and balance
- providing mechanical support of motion
3 different assessments of posture
- examination of alignment in standing
- tests for flexibility and m. length
- tests for muscle strength
ant view assessment
- forehead,
- nose
- manubrium
- umbilicus
- even spacing btw feet
post view assessment
- occiput
- spine
- sacrum
- equal distance of feet
laeral view
- ear
- greater tubercle
- l3
- asis
- kn lat condyle
- med malleolus
upper cross syndrome
- tight upper trap and lev scap
- tght pecs
- weak deep cervical flex
- weak rhomboids, serratus ant, MFT, LFT
jnt dysfunction with UCS
atlanto occipital
C4-C5
ccervicothoracic jnt
GH jnt
- T4-T5
Lower cross syndrome
- tight thoracolumbar extensors
- tight iliopsoas and rec fem
- weak deep abd
- weak glu max and medius
jnt dysfunction w/ lower cross syndrome
- L4-L5,
- L5-S1
- SI
- hip jnt
normal deg of pronation during gait
6-8deg
forces sustained by the lower leg
- tension, compression, bending, torsion
weight distribution when walking
- 50% subtalar jnt to calcareous
- 50%: transvers tarsal jnts to the forefoot
plantar foot distribution depends on:
- gender
- shoe type,
- support surface
- fatigue
- foot conformation
- gait characteristics
which compartmet of the kn sustaines more presssure in stance phase
medial
body weight on kne during
- stance
- stair climbing
-
stance
- 3x
stairs
- 3-6x
knee motion during midstance of normal gait
- 20deg flex
- 5deg int rot
- slight abd
knee motion during swing phase
70deg flex
15 deg int rot
- 5deg add
swayback
- dec ant lumbar curve, inc post thoracic curve
- head and sup aspect of femur to shift ant to compensate for post position
- ## inc lordosis and kyphosis
forces at the hip during standing
1/2 weight on each hip
forces at the hip during gait
- compression same as BW during swing phase - inc 3-6 fold BW during stance phase
basic gait cycle phases/components
stance phase
- initial contact
- loading response
- midstance
- terminal stance
- preswing phase
SWING phase
- initial swing
- mid swing
- terminal swing
components when assessing gait and normal values
Width of normal base: 2-4 inc, heel to heel (15inc)
Center of Gravity: 2 inc in front of sacral vertebrae
Knee remain flex: except initial contact
Pelvis and truck shift laterally 1 inch to the weight bearing side
length of step: 15 inch
cadence: 90-120 STEPS/MIN
swing phase: pelvis rotates 40deg,
