Flashcards in Posture Deck (41):
1

What does normal standing posture entail?

Economical, requiring little muscular effort
Minimal stress on supporting structures, joints and ligaments
optimal room for chest and abdominal cavities

2

What planes do you perform a postural exam?

Sagittal and anterior/posterior views from head to toe systematically.

3

What do you record in a postural exam?

Deviations

4

What is a plumb line used for?

In reference to line of gravity

5

What does ideal posture look like from the side?

Head centered
Cervical lordosis
Thoracic kyphosis
Lumbar lordosis
ASIS close to level with PSIS

6

Where does the ideal line of gravity fall

Behind hip axis
anterior to knee axis
anterior anterior to ankle axis (lateral malleolus)

This promotes extension @ hip and knee and neutral position @ ankle to promote comfortable standing

7

How do you name scolosis?

By the convexity. If convexity is on right it is right spinal scolosis

8

Where does the pelvic center of rotation fall in sway-back posture?

Very far posterior to the pelvis. See significant
Recervatum- hyper extenstion

9

What happens to the pelvis in Hyper lordosis?

anteriorly tilted pelvis

10

What happens to the knees in Hyper lordosis?

may be flexed

11

What happens to the ankles in Hyper lordosis?

slightly flexed

12

What muscles are tight in Hyper lordosis?

lumbar spinal extensors, hip flexors

13

What muscles are lengthened in Hyper lordosis?

Abdominals

14

What happens to the scapulae with excessive thoracic kyphosis?

protracted

15

What happens to the head with excessive thoracic kyphosis?

forward with c spine extension

16

What happens to the thoracic spine curve with excessive thoracic kyphosis?

Increased curve in thoracic spine

17

What happens to the hips and knees with excessive thoracic kyphosis?

hips slightly flexed; knees hyperextended

18

What muscles are tight with excessive kyphosis?

neck extensors, hip flexors, pec maj and minor, serratus anteroir

19

What muscles are lengthened with excessive kyphosis?

mid and lower trapezius, rhomboids, thoracic erector spinae

20

What happens to the head with swayback?

head is forward of the shoulders

21

What happens to the neck with swayback?

neck is slightly extended

22

What happens to the thoracic spine with swayback?

uppe rback has an increased curve, convex backwards. Upper back is displaced backwards in regards to the lower back

23

What happens to the lumbar spine with swayback?

Lower back has a decreased (flattened) curve

24

What happens to the Hip joints with swayback?

Both hips are generally hyperextended with hips forward of ankles and knees

25

What happens to the knee joints with swayback?

both knees are hyperextended

26

What happens to the ankle joints with swayback?

the ankles are in a neutral position i.e. let is at right angles to the sole of the foot

27

What muscles are tight with a sway back posture?

Hip extensors, hamstrings

28

What muscles are lengthened in sway back posture?

one joint hip flexors, lower abdominals

29

What happens with a flat back posture?

posterior pelvic tilt
extended hips
hyperextended knees

30

What is the cause of scoliosis?

Idiopathic adolescent (most common)- not really known
some neuromuscular weakness
some vertebral malformation

31

What is scoliosis?

Lateral curvature of the spine

32

What other motion is also associated with scoliosis?

The lateral curve is usually associated with a rotation

33

On what side of the scoliosis will the ribs protrude?

on the convex side of the curve

34

How will the arm, scapulae and belvis present with scoliosis?

They will have asymmetries

35

What are the two types of leg length discrepancy?

True length differences (measure)- birth or injury
Functional (apparent length differences) -2deg scoliosis, ilial torsions, knee/ankle dysfunction

36

What is tibial torsion?

Rotation of tibia, may be associated with flat foot

37

What is Genu Recurvatum?

Knee hyper extension seen in the sagittal plane

38

What is Genu Varus?

"bowlegged". knee joint angled medially
Often see in OA

39

Flat feet tend to be more?

flexible

40

High arches tend to be more?

rigid

41

What is Genu Valgus?

"knock-kneed"
Common in RA, other malalignment
